Mechanism, regulatory status, published research and registered trials for each compound — counted from the source registries, not estimated.
A long-acting GLP-1 receptor agonist given once weekly. It slows gastric emptying and acts on hypothalamic appetite signalling, and it carries th…
A dual agonist hitting both the GIP and GLP-1 receptors. Head-to-head trials show greater average weight reduction than single-agonist GLP-1s, at…
A stabilised growth-hormone-releasing hormone analog and the only approved GH secretagogue. Approved specifically to reduce excess visceral fat i…
The only human cathelicidin antimicrobial peptide, part of innate immune defence. Extensively characterised in immunology research; therapeutic u…
The naturally occurring 43-amino-acid parent protein that TB-500 is derived from. It has been evaluated in registered trials for corneal and derm…
A 28-amino-acid immune-modulating peptide that promotes T-cell maturation. Used clinically in a number of countries as an adjunct in hepatitis B…
A melanocortin receptor agonist acting on central pathways rather than on blood flow. Approved as bremelanotide for hypoactive sexual desire diso…
A nonapeptide first isolated from rabbit cerebral venous blood during induced sleep. Named for its proposed effect on slow-wave sleep, though fin…
A mitochondrial-derived peptide that activates AMPK and is described in the literature as an exercise mimetic. Research is almost entirely precli…
An investigational triple agonist adding glucagon-receptor activity to the GIP/GLP-1 mechanism. Trial results to date report the largest average…
A naturally occurring copper-binding tripeptide with a long record in skin research, where it is linked to collagen synthesis and wound remodelli…
A pentapeptide GH secretagogue selective for the ghrelin receptor, so it raises growth hormone without the cortisol and prolactin rise seen with…
A synthetic pentadecapeptide derived from a sequence found in gastric juice. The preclinical record for tendon, ligament and gut-lining repair is…
A synthetic ACTH fragment analog without corticotropic activity, studied for neuroprotection and cognition. As with Selank, the evidence base is…
A synthetic tetrapeptide studied largely by a single research group for telomerase activation and circadian regulation. Independent replication i…
The C-terminal tripeptide of α-melanocyte-stimulating hormone, studied for anti-inflammatory activity in gut models without the pigmentation effe…
A synthetic analog of the immunomodulatory peptide tuftsin, developed in Russia as an anxiolytic. Most of the published work originates from Russ…
A GHRH analog that extends and amplifies natural growth-hormone pulses. The DAC version binds albumin for a much longer half-life. Commonly paire…
A synthetic fragment corresponding to the actin-binding region of Thymosin β4. Marketed for systemic repair and often stacked with BPC-157. Most…
A fragment of human growth hormone investigated as a fat-loss agent. Registered obesity trials did not show weight loss superior to placebo, and…
The grade is not a hand-assigned opinion. It is derived from the retrieved counts by a fixed rule, so it can be recomputed and checked:
Publication and trial counts retrieved 2026-07-23 from PubMed and ClinicalTrials.gov. Trial counts include only studies listing the compound as an intervention. Each peptide page links the exact query used, so any figure here can be re-run at source.
Counts measure how much a compound has been studied — not whether it works, and not whether it is safe or legal to use.
Our mission is to make peptide research clear, credible, and usable for people who refuse to rely on hype.
