These are sourced notes, not a record of what I use. Evidence labels describe the underlying research, not a recommendation.
10
Three ingredients in one vial. Nothing has been studied about the combination itself.
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 composition here exists so the calculator can do the math. Putting three compounds in one vial and naming it does not create evidence for the mixture, and the injectable GHK-Cu claims are considerably weaker than the topical research they borrow from.
20
A four-way repair blend, sold on skin and inflammation language.
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 here for identification and dose math. Four ingredients means four separate evidence questions, and several of them are answered mostly by animal studies.
30
Two research compounds, neither with controlled human evidence behind the claims.
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 name is marketing. Judge the two ingredients separately: BPC-157 has no randomized human trials, and TB-500 is not the same thing as the full-length thymosin beta-4 its research is borrowed from.
40
A three-part repair blend named after the outcome it has not demonstrated.
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.
Worth stating plainly: “Healing” is what the vendor called it. No study attaches to this combination.
50
Two compounds pushing growth-hormone release through different receptors.
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 pairing has a real physiological rationale: the two compounds act on different receptors that both feed GH release. That is a reason to expect something, not evidence that this fixed ratio does what is claimed. Note the “without DAC” - the long-acting version is a different drug.
60
No standard composition exists. Read the actual label.
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 deliberately has no calculator link, because there is no formula to compute against. Anyone selling you “Beauty” has to tell you what is in it before the question of evidence can even be asked.
110
Enormous popularity, animal-and-lab evidence only.
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 is the whole story. BPC-157 is everywhere in injury-recovery discussion, and Huberman is direct that the randomized human trials do not exist. The animal work is genuinely interesting, which is not the same as knowing what it does in people.
120
The research is on thymosin beta-4. The product usually is not.
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.
One rule covers this entry: evidence about thymosin beta-4 is not evidence about whatever is in a vial labelled TB-500. The names get used interchangeably in marketing copy and they should not be.
130
Decent evidence on skin. Much thinner evidence in a syringe.
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 is the entire question. GHK-Cu has a legitimate cosmetic research base, and all of it is topical. That data quietly migrates into marketing for injectable blends where it does not apply.
210
Short-acting. Not the DAC version, despite the shared name.
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 qualifier matters. This one clears quickly and is meant to mimic natural GH pulses; the DAC version sticks around for days. Findings about one do not transfer to the other, and vendors are careless about which they are selling.
220
Human studies show it raises GH and IGF-1. What that buys you is a separate question.
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.
Raising a hormone is a measurement, not an outcome. The trials establish that GH and IGF-1 go up and stay up; they do not establish that this makes anyone healthier, and sustained elevation is a different physiological state from the natural pulses.
230
Clean pharmacology, thin outcome evidence for how it is actually used.
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.
Its selectivity is the selling point - it triggers GH release without much of the cortisol and prolactin effect older secretagogues had. Real pharmacology. It still does not demonstrate the recovery, sleep, or body-composition results attached to it.
240
More established than most of this library. The wellness claims are still not the studied use.
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.
Its clinical history is real, and it is a history of diagnostics and deficiency, not of healthy adults chasing recovery. Huberman’s public post about his own PSA and sleep is one person’s report — useful for raising the question, worthless for predicting your result.
250
Genuine approval and trial evidence, attached to one specific condition.
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.
The best illustration on this page of why “has human evidence” is an incomplete sentence. Tesamorelin has the strongest regulatory footing of any GH-axis entry here, for reducing visceral fat in HIV-associated lipodystrophy. That is not evidence for using it to lean out.
310
It was properly tested for fat loss. That is the problem - it was tested and disappointed.
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.
Usually the complaint about these compounds is untested. Here the opposite: it was tested in humans for obesity and the results did not support the hypothesis. Still sold on the original mechanism story, with the trial history left out.
320
Strong outcome data in the studied populations. Whether it suits you is a medical conversation.
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.
330
Mature evidence. Trial averages still do not tell you your own answer.
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.
340
Promising and unfinished. Long-term safety is not yet in.
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.
350
Real endogenous biology, early evidence for the injectable version.
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.
Three separate steps get collapsed in the marketing: the body makes it, higher natural levels correlate with better metabolic health, and therefore injecting it helps. The first two are established. The third does not follow from them.
140
Interesting inflammatory research, essentially all preclinical.
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.
Early research, not a therapy. Appearing as an ingredient in several sold blends says something about marketing, not about evidence.
430
Real clinical evidence, tied to particular diseases and places.
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.
Modulation, not boosting. The distinction is not pedantry: the trials are in people with specific conditions - hepatitis, sepsis, some cancers - and what helps a compromised immune system is not a general upgrade for a working one.
510
Afamelanotide is a regulated implant. A research vial is not that.
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.
Afamelanotide is approved for a rare light-sensitivity disorder, delivered as a controlled implant under supervision. Sharing a molecule name with a grey-market vial does not transfer any of the manufacturing, dosing, or oversight that evidence depended on.
520
No approved version. Sold for tanning through research-product channels.
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 lack of selectivity is the point and the problem: the same broad receptor activity that drives pigmentation also drives nausea, appetite suppression, and arousal effects. Sold entirely through unregulated channels, so identity and purity are open questions on top of that.
530
Approved as bremelanotide for one indication. A research vial is a different proposition.
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.
Bremelanotide is approved for hypoactive sexual desire disorder in premenopausal women, which is a narrow indication and not how PT-141 is generally discussed. The trial evidence describes a manufactured, dosed drug; it says nothing about the contents of an unregulated vial.
410
The name is a hypothesis from decades ago, not a finding.
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.
The studies are old, small, and inconsistent, and researchers still disagree about what it does naturally. If you want something for sleep, the boring options have far better evidence.
420
Big claims, thin and largely unreplicated evidence.
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.
Most of the cited research traces to a small number of older studies from one research group, much of it difficult to access or independently verify. That is a reason for caution regardless of how appealing the telomerase story sounds.
