GLOW

A three-component repair blend whose evidence is inherited from its individual ingredients, not the combined vial.

Composition
57.27 mg GHK-Cu · 12.54 mg BPC-157 · 10.45 mg TB-500
Common context
Marketed as a combined tissue, skin, and recovery blend.
Mechanism, evidence, and sources

Mechanism: Combines copper-peptide signaling with two research compounds discussed around tissue-repair pathways; a combined mechanism has not been established clinically.

Evidence: The named blend has no established clinical evidence as a formulation. Evidence must be assessed component by component, and the injectable claims are generally weaker than topical GHK-Cu research.

The calculator composition is the identity layer for this named vial. The label does not create evidence for the blend as a whole.

  • Local Pep-Pedia-derived dataset — Identity and named-blend context only; old dose, cycle, storage, and outcome strings were excluded.
  • Andrew Huberman — Notes that BPC-157 lacks randomized human trials.
  • Andrew Huberman — Independent identity and purity testing context for peptide products.

KLOW

A four-component blend commonly framed around skin, tissue, and inflammatory signaling.

Composition
15 mg GHK-Cu · 5 mg TB-500 · 5 mg BPC-157 · 2 mg KPV
Common context
Sold as a broad repair-oriented blend with skin and inflammatory-signaling language.
Mechanism, evidence, and sources

Mechanism: Pairs copper-peptide signaling with three research peptides discussed around tissue and inflammatory pathways; the combination itself has not been clinically characterized.

Evidence: Evidence is extrapolated from four separate components. The named combination has no established human evidence, and several components remain primarily preclinical research topics.

The component list is useful for catalog and calculator identity. It should not be read as proof that the ingredients work better together.

  • Local Pep-Pedia-derived dataset — Identity and blend composition provenance only.
  • Andrew Huberman — Broad peptide-category framing rather than evidence for this proprietary blend.
  • Andrew Huberman — Independent product-testing context.

Wolverine

A two-component repair blend built from two research compounds with limited or absent controlled human evidence.

Composition
5 mg TB-500 · 5 mg BPC-157
Common context
Commonly marketed for injury recovery and connective-tissue support.
Mechanism, evidence, and sources

Mechanism: Combines two compounds discussed around angiogenesis, cell migration, and tissue-repair signaling; a clinically validated combined mechanism is not established.

Evidence: The blend has no established clinical evidence. BPC-157 lacks randomized human trials, while TB-500 product identity should not be conflated with full-length thymosin beta-4 research.

The memorable name is marketing language. Each component needs to be judged independently.

  • Local Pep-Pedia-derived dataset — Named blend and composition provenance only.
  • Andrew Huberman — Explicitly distinguishes BPC-157 discussion from randomized human-trial evidence.

Healing

A repair-oriented three-component vial whose name should not be mistaken for a demonstrated outcome.

Composition
5 mg TB-500 · 2.5 mg BPC-157 · 2 mg KPV
Common context
Marketed around tissue recovery and inflammatory signaling.
Mechanism, evidence, and sources

Mechanism: Groups research compounds associated with tissue and inflammatory pathways; no validated mechanism exists for the fixed blend.

Evidence: The formulation does not have established clinical evidence. Its name is promotional, and the evidence base is limited to separate component research.

“Healing” is the product name, not an evidence claim.

  • Local Pep-Pedia-derived dataset — Blend identity and calculator composition provenance only.
  • Andrew Huberman — Independent product-testing context is especially relevant to compounded blends.

CJC-1295 / Ipamorelin

A paired growth-hormone-axis blend combining GHRH- and ghrelin-receptor signaling.

Composition
2 mg CJC-1295 without DAC · 5 mg Ipamorelin
Common context
Discussed as a paired growth-hormone secretagogue formulation.
Mechanism, evidence, and sources

Mechanism: CJC-1295 without DAC is a short-acting GHRH analog; ipamorelin is a ghrelin-receptor agonist. Both can signal toward pulsatile growth-hormone release.

Evidence: The physiological rationale comes from the two signaling pathways, but the fixed commercial blend has limited direct human evidence and should not inherit claims made for other GH-axis drugs.

The “without DAC” distinction matters because it separates this entry from the longer-acting CJC-1295 with DAC record.

  • Local Pep-Pedia-derived dataset — Paired-protocol identity and calculator composition provenance only.
  • Andrew Huberman — Places GH secretagogues within a broader peptide-category framework.

Beauty

“Beauty” is not a stable formula; the vial label and vendor documentation have to define the ingredients.

Composition
Vendor-specific composition; verify the vial label
Common context
Usually marketed with skin, hair, or cosmetic-recovery language.
Mechanism, evidence, and sources

Mechanism: No blend-level mechanism can be assigned until the actual components are known.

Evidence: There is no single Beauty formulation to evaluate. Any evidence review must start with the exact ingredients and amounts on the specific product label.

This entry intentionally has no calculator ID. A formula should not be guessed from the product name.

  • Local Pep-Pedia-derived dataset — Used only to preserve the common vendor name; no standard formula was inferred.
  • Andrew Huberman — Independent identity and purity testing is relevant when a marketing name does not define a standard formula.

BPC-157

Popular in injury-recovery conversations, but randomized human trials are absent.

Identity
Body Protection Compound 157
Common context
Experimental tendon, ligament, muscle, and gastrointestinal repair discussions.
Mechanism, evidence, and sources

Mechanism: Preclinical work explores angiogenesis, nitric-oxide signaling, cell migration, and tissue-repair pathways; a therapeutic human mechanism is not established.

Evidence: Mechanistic and animal findings do not establish human benefit. Andrew Huberman explicitly notes the lack of randomized human trials.

The gap between widespread community use and controlled human evidence is the central fact to keep visible.

  • Local Pep-Pedia-derived dataset — Identity and community context only; dosing and outcome claims were excluded.
  • Andrew Huberman — States that BPC-157 lacks randomized human trials.

TB-500

Discussed around tissue repair and cell migration, but it is not interchangeable with full-length thymosin beta-4.

Identity
Thymosin beta-4 fragment product
Common context
Experimental soft-tissue recovery, wound repair, and mobility discussions.
Mechanism, evidence, and sources

Mechanism: Thymosin beta-4 biology includes actin binding, cell migration, and wound-repair signaling; the identity and equivalence of TB-500 products require care.

Evidence: Some human research exists for full-length or formulated thymosin beta-4, but that evidence cannot automatically be assigned to products sold as TB-500.

The key reading rule is simple: evidence on thymosin beta-4 is not automatically evidence on every TB-500 vial.

  • Local Pep-Pedia-derived dataset — Identity and community context only; kept distinct from full-length thymosin beta-4.
  • Andrew Huberman — Independent identity and purity testing context.

GHK-Cu

The topical skin evidence is more mature than claims made for injectable GHK-Cu.

Identity
Copper tripeptide-1
Common context
Topical skin-care and hair products; also appears in injectable community blends.
Mechanism, evidence, and sources

Mechanism: Binds copper and is studied in extracellular-matrix, wound-remodeling, and gene-signaling contexts.

Evidence: Human cosmetic research is largely topical. It should not be used as direct support for injectable dosing, systemic outcomes, or proprietary blends.

Route matters here. Topical data should stay labeled as topical rather than silently migrating into injectable claims.

  • Local Pep-Pedia-derived dataset — Topical protocols and injectable calculator identity were kept separate during curation.
  • Andrew Huberman — Independent testing context for nonstandard injectable products.

CJC-1295 without DAC

The short-acting “without DAC” version is distinct from long-acting CJC-1295 with DAC.

Identity
Modified GRF 1-29
Common context
Growth-hormone-axis research and paired CJC/ipamorelin formulations.
Mechanism, evidence, and sources

Mechanism: Mimics growth-hormone-releasing hormone signaling at the pituitary, with a shorter exposure profile than the DAC-bound analog.

Evidence: Human evidence for this short-acting formulation and common compounded protocols is limited. Findings from CJC-1295 with DAC should not be silently transferred to it.

The label needs the “without DAC” qualifier because the two CJC entries have materially different pharmacologic intent.

  • Local Pep-Pedia-derived dataset — Identity and “without DAC” distinction only.
  • Andrew Huberman — Growth-hormone secretagogue category context.

CJC-1295 with DAC

Human studies show prolonged GH/IGF-1 signaling, but that is not the same as proven long-term health benefit.

Identity
CJC-1295 DAC
Common context
Long-acting growth-hormone-axis research.
Mechanism, evidence, and sources

Mechanism: The DAC design binds circulating albumin and extends GHRH-receptor stimulation compared with short-acting analogs.

Evidence: Early human trials characterize hormone responses and pharmacokinetics. They do not establish broad anti-aging, body-composition, or performance outcomes.

Hormone elevation is an intermediate measurement, not proof of a desired clinical outcome.

Ipamorelin

Often paired with a GHRH analog, but direct outcome evidence for community protocols is limited.

Identity
Single compound
Common context
Growth-hormone-axis and paired CJC/ipamorelin discussions.
Mechanism, evidence, and sources

Mechanism: Activates the ghrelin receptor to stimulate growth-hormone release, with selectivity that differentiates it from some earlier secretagogues.

Evidence: Pharmacology and small studies do not establish the recovery, sleep, body-composition, or longevity claims commonly attached to compounded use.

The pairing rationale is physiological; it is not equivalent to clinical validation of a fixed blend.

  • Local Pep-Pedia-derived dataset — Identity and paired-protocol context only.
  • Andrew Huberman — Growth-hormone secretagogue category context.

Sermorelin

Better tied to human use than many research peptides, but wellness and longevity outcomes remain uncertain.

Identity
GRF 1-29
Common context
Growth-hormone evaluation and off-label secretagogue discussions.
Mechanism, evidence, and sources

Mechanism: Stimulates pituitary GHRH receptors and endogenous growth-hormone release.

Evidence: Historical human use supports its GHRH activity, not broad claims about sleep, recovery, body composition, or aging. Andrew Huberman’s PSA/sleep post is a personal anecdote, not a trial.

The public personal report is useful as a question generator, not as evidence that others should expect the same result.

  • Local Pep-Pedia-derived dataset — Identity and community context only.
  • Andrew Huberman — Personal PSA and sleep anecdote; explicitly not clinical outcome evidence.

Tesamorelin

Has real human trial and clinical-use evidence, but only for defined indications—not general fat loss or longevity.

Identity
Single compound
Common context
HIV-associated lipodystrophy and off-label metabolic discussions.
Mechanism, evidence, and sources

Mechanism: Stimulates endogenous growth-hormone release through GHRH receptors, influencing IGF-1 and visceral-fat metabolism.

Evidence: Condition-specific approval and trials make this evidence base more mature than most entries here. That does not generalize to routine body recomposition or anti-aging use.

This is the clearest example on the page of why “has human evidence” still needs an indication attached.

  • Local Pep-Pedia-derived dataset — Identity and community context only; condition-specific evidence remains the important distinction.
  • Andrew Huberman — Places tesamorelin within the GH-axis peptide category.

AOD-9604

Reached human obesity trials, but the existence of trials does not mean the weight-loss hypothesis was confirmed.

Identity
HGH fragment 176-191 analog
Common context
Experimental fat-loss and metabolic research.
Mechanism, evidence, and sources

Mechanism: Designed around a region of growth hormone associated with lipolytic signaling while attempting to avoid full GH growth effects.

Evidence: Human development included obesity studies, yet efficacy was not established as hoped. Community positioning should not erase that negative or inconclusive history.

This entry is a reminder that a plausible mechanism and human testing can still lead to an unconvincing outcome.

Semaglutide

Strong outcome evidence in defined populations; benefits, tradeoffs, and appropriateness remain individual.

Identity
Single compound
Common context
Type 2 diabetes, obesity treatment, and cardiometabolic-risk discussions.
Mechanism, evidence, and sources

Mechanism: Activates GLP-1 receptors, affecting appetite, gastric emptying, insulin signaling, and glucagon regulation.

Evidence: This has far more mature evidence than most entries here. Layne Norton emphasizes reduced energy intake as a major mechanism and questions universal use; that framing does not replace individualized medical assessment.

The evidence is strong enough that the useful questions move from “does it do anything?” to indication, tradeoffs, adherence, lean-mass protection, and long-term planning.

  • Local Pep-Pedia-derived dataset — Identity and catalog provenance only.
  • Layne Norton — Frames reduced energy intake as central to GLP-1-associated weight loss.
  • Layne Norton — Raises the question of whether use should be universal rather than assuming it is.

Tirzepatide

A mature incretin therapy whose average trial results still do not answer every individual-use question.

Identity
Single compound
Common context
Type 2 diabetes, obesity treatment, and cardiometabolic-risk discussions.
Mechanism, evidence, and sources

Mechanism: Activates GIP and GLP-1 receptors, influencing appetite, glucose regulation, insulin signaling, and gastric function.

Evidence: Evidence supports substantial metabolic effects in studied populations. Layne Norton’s energy-intake framing and non-universal-use question keep the mechanism and decision context grounded.

As with semaglutide, treatment evidence and a personal decision are related but separate layers.

  • Local Pep-Pedia-derived dataset — Identity and catalog provenance only.
  • Layne Norton — Energy-intake framing for incretin-associated weight loss.
  • Layne Norton — Questions the idea of universal GLP-1 use.

Retatrutide

Promising human trial results, but it remains an emerging therapy rather than an established finished story.

Identity
Single compound
Common context
Obesity, metabolic disease, and next-generation incretin research.
Mechanism, evidence, and sources

Mechanism: Combines GIP and GLP-1 receptor agonism with glucagon-receptor activity to affect appetite, glucose regulation, and energy expenditure.

Evidence: Human trials support meaningful metabolic effects, while longer-term outcomes and broader claims remain under study. Attia’s geroprotection/cognition comments and Patrick’s genetics context are emerging hypotheses, not settled indications.

The triple-receptor design is the headline, but trial phase, duration, tolerability, and final indications still matter more than novelty.

  • Local Pep-Pedia-derived dataset — Identity and catalog provenance only.
  • Peter Attia — Emerging GLP-1 geroprotection and cognition context; speculative beyond established metabolic outcomes.
  • Rhonda Patrick — Emerging GLP-1 receptor genetics context; not direct retatrutide outcome evidence.

MOTS-c

Biologically interesting and associated with human physiology, but therapeutic injection evidence remains early.

Identity
Mitochondrial open reading frame of the 12S rRNA-c
Common context
Mitochondrial function, exercise adaptation, insulin sensitivity, and healthy-aging research.
Mechanism, evidence, and sources

Mechanism: Studied as a mitochondrial stress signal that can influence cellular metabolism, AMPK-related pathways, and adaptation to energetic demand.

Evidence: Human observational and early translational work does not establish the benefits claimed for exogenous MOTS-c products.

Endogenous biology, association studies, and an injectable intervention are three different evidence steps.

KPV

A three-amino-acid peptide with mostly laboratory and animal evidence around inflammatory signaling.

Identity
Lysine-proline-valine
Common context
Experimental gut, skin, and inflammatory-signaling discussions; also included in named blends.
Mechanism, evidence, and sources

Mechanism: Studied for effects on inflammatory transcription and immune signaling, including pathways often described around NF-kappa-B.

Evidence: The research base is predominantly preclinical. Community use and blend inclusion do not establish clinical efficacy.

KPV is best treated as an early research topic rather than a settled anti-inflammatory therapy.

Thymosin alpha-1

More clinically studied than many research peptides, but evidence remains condition- and jurisdiction-specific.

Identity
Thymalfasin
Common context
Immune modulation, infection, and oncology-adjunct research.
Mechanism, evidence, and sources

Mechanism: Modulates innate and adaptive immune signaling, including dendritic-cell and T-cell activity.

Evidence: Human trials and international medical use exist, but results depend on the condition and regimen. That does not support general “immune boosting” claims.

“Immune modulation” is more accurate than “immune boost” because the clinical question changes by disease and immune state.

Melanotan I

Community “Melanotan I” products should not be treated as equivalent to the regulated afamelanotide implant.

Identity
Afamelanotide-related analog
Common context
Experimental tanning and pigmentation discussions.
Mechanism, evidence, and sources

Mechanism: Activates melanocortin-1 receptors and promotes eumelanin production.

Evidence: Afamelanotide has condition-specific human evidence as a controlled implant. That formulation and oversight do not validate unregulated products sold as Melanotan I.

Related molecule names do not make the sourcing, formulation, or evidence interchangeable.

Melanotan II

Human exposure exists, but community tanning use is not an established regulated indication.

Identity
Single compound
Common context
Experimental tanning and sexual-function discussions.
Mechanism, evidence, and sources

Mechanism: Activates multiple melanocortin receptors, affecting pigmentation and central pathways involved in appetite and sexual response.

Evidence: Small human studies and derivative-drug development do not establish the safety or quality of Melanotan II sold through research-product channels.

The broad receptor activity is part of both the interest and the uncertainty around this compound.

PT-141

Branded bremelanotide has condition-specific evidence; a research vial labeled PT-141 is not automatically the same product.

Identity
Bremelanotide-related product
Common context
Sexual-interest and arousal discussions.
Mechanism, evidence, and sources

Mechanism: Acts centrally through melanocortin receptors involved in sexual-response pathways rather than through peripheral vasodilation alone.

Evidence: A regulated bremelanotide product has human trial and clinical-use evidence for a defined indication. That evidence should not be transferred wholesale to compounded or research-market PT-141.

The clinically studied molecule provides useful context, but formulation and product quality remain separate questions.

DSIP

The name promises more clarity than the inconsistent and limited research actually provides.

Identity
Delta sleep-inducing peptide
Common context
Experimental sleep, stress, and pain discussions.
Mechanism, evidence, and sources

Mechanism: Proposed to influence sleep and neuroendocrine regulation, but a consistent therapeutic mechanism has not been established.

Evidence: Small and older studies are heterogeneous, and the peptide’s endogenous role remains debated. It is not an established insomnia treatment.

“Sleep-inducing” is part of the name, not a reliable summary of clinical effect.

Epitalon

Longevity claims run well ahead of the small, difficult-to-verify human evidence base.

Identity
Epithalon
Common context
Experimental healthy-aging, circadian, and telomere discussions.
Mechanism, evidence, and sources

Mechanism: Proposed effects include pineal signaling, oxidative-stress pathways, and telomerase-related activity, with uncertain clinical relevance.

Evidence: Much of the cited work is small, older, or not easily generalized. Telomerase and lifespan narratives should be treated as hypotheses rather than demonstrated human outcomes.

This is an entry where source quality matters as much as the headline finding.
