A coenzyme and metabolic molecule. It belongs in a separate longevity evidence track, not inside the peptide library.

Signal over sales noise.
What a compound is. What it has actually been studied for. What is licensed, investigational or still preclinical — with the uncomfortable unknowns left in.
Education only. No diagnosis, dosing, reconstitution, injection or purchasing guidance.A regulator has authorised a specific product for a specific indication.
People have been studied, but approval and general use do not follow automatically.
Small or route-specific evidence that needs careful interpretation.
Laboratory and animal signals — useful for hypotheses, not treatment promises.
Current signal wire
Today in the evidence.
Registry titles are pulled from the official ClinicalTrials.gov feed. We show the source record rather than turning every update into a claim.
Compound library
Know the status before the story.
Every profile separates regulated uses from research interest, gaps, safety signals and sport status.
Tesamorelin
A synthetic analogue of growth hormone-releasing factor that increases endogenous growth hormone signalling and IGF-1.
Ipamorelin
A growth hormone secretagogue studied as a ghrelin-receptor agonist, including trials in post-operative gastrointestinal recovery.
BPC-157
An experimental peptide widely promoted online for tissue and gastrointestinal recovery, despite the gap between preclinical research and proven human treatment.
TB-500
Thymosin beta-4 fragment (LKKTETQ)
A short synthetic fragment associated with thymosin beta-4 marketing. Evidence for full thymosin beta-4 should not be treated as evidence for TB-500.
GHK-Cu
Copper tripeptide-1
A naturally occurring copper-binding tripeptide studied in skin biology, extracellular-matrix signalling and cosmetic formulations.
Retatrutide
LY3437943
An investigational triple receptor agonist being studied in phase 3 programmes for obesity and related metabolic conditions.
PT-141 / Bremelanotide
Bremelanotide is a synthetic cyclic peptide and melanocortin-receptor agonist. 'PT-141' material sold online should not be assumed equivalent to a regulated medicine.
Selank
A synthetic peptide related to tuftsin, promoted online for anxiety, stress and cognitive effects despite a limited and hard-to-generalise evidence base.
KPV
Lys-Pro-Val
A three-amino-acid fragment associated with alpha-melanocyte-stimulating hormone research and promoted for inflammatory and wound-healing uses.
Melanotan I / Afamelanotide
Afamelanotide is a synthetic alpha-MSH analogue. The regulated Scenesse implant must not be confused with unlicensed 'Melanotan I' tanning products.
Melanotan II
An unapproved melanocortin analogue promoted online for tanning and sexual effects, often through products with uncertain identity and purity.
Keep the categories straight
NAD+ is not a peptide. TRT is not research supply.
Prescription-only hormone therapy requiring symptoms, appropriately timed blood tests, clinical review and ongoing monitoring.

The library does not contain buy buttons, dosing protocols or human-use instructions for unapproved substances. “Research use only” text does not neutralise a medicinal claim or make an unlicensed consumer product lawful.
