Peptide library

What are you looking to improve.

Browse by what you want, not by molecule names. Each peptide on Panya is tagged with the effects it produces (recovery, sleep, cognition, muscle growth, longevity, more) so you can land at the right entry without already knowing the chemical name.

Each page covers mechanism, typical practice, regulatory status by region, risks, citations, and vendor names worth your own diligence. We cover what users search for, regardless of evidence strength or risk band; missing pages are bugs, not features.

For prescription peptides like Mounjaro, Wegovy, and Ozempic, Panya does match you to licensed clinicians. See /vendor or the quiz for that path.

Sermorelin
peptidemedium risk
growth hormone secretagogue
Muscle growthLongevity
aka GHRH 1-29 · Sermorelin Acetate

Sermorelin is the first 29 amino acids of human growth-hormone-releasing hormone (GHRH). FDA-approved for pediatric GHD until 2008; since then sold compounded for off-label adult anti-aging and recovery use. Less popular...

Ipamorelin and CJC-1295
peptidemedium risk
growth hormone stack, dual-axis
Muscle growthRecovery + healing
aka Ipamorelin · CJC-1295 · CJC-1295 DAC · GHRP-Ipamorelin · Ipa-CJC stack

The most commonly stacked GH-axis pair in current peptide community use. Ipamorelin is a selective ghrelin-receptor agonist that triggers GH release without the appetite or cortisol bumps of older GHRPs. CJC-1295 is a lo...

MK-677
small moleculemedium risk
oral GH-secretagogue, sleep + appetite
Muscle growthSleep
aka Ibutamoren · Ibutamoren Mesylate · MK-0677

MK-677 is an orally-active ghrelin receptor agonist developed by Merck in the 1990s. Stimulates GH and IGF-1 release through the same axis ipamorelin uses, but in pill form. Trial data is robust, including a long-term Al...

Tesamorelin
peptidemedium risk
visceral fat reduction (FDA-approved for HIV lipodystrophy)
Metabolic + weightMuscle growth
aka Egrifta · TH9507

Tesamorelin is an FDA-approved GHRH analog (Egrifta) for HIV-associated visceral lipodystrophy. Real prescription-routable peptide with multi-trial data showing 15-18% visceral adipose tissue reduction at 2 mg / 26 weeks...

Hexarelin
peptidemedium risk
GH-secretagogue, body composition, contested cardiac signal
Muscle growthCardiac
aka HEX · Examorelin · MF-6003

Hexarelin is a synthetic hexapeptide that stimulates growth hormone release through the ghrelin receptor. Stronger GH pulse than Ipamorelin; also higher cortisol and prolactin spike, and faster tachyphylaxis with chronic...

IGF-1 LR3
peptidemedium risk
muscle growth, recovery, metabolic recomposition (off-label)
Muscle growth
aka Long-Arg3 IGF-1 · Receptor-grade IGF-1 LR3 · rhIGF-1 LR3

IGF-1 LR3 is a synthetic 83-amino-acid analogue of insulin-like growth factor 1 with the N-terminal extended by 13 residues and Glu3 substituted with Arg3. The modifications extend serum half-life from 10-20 minutes (nat...

Follistatin

muscle growth via myostatin inhibition (off-label)
Muscle growth
aka FST · FST-288 · FST-315 · FST-344 (research naming)

Follistatin is an endogenous 288-residue glycoprotein that binds and neutralises members of the TGF-beta superfamily including activin, BMPs, and myostatin (GDF-8). Inhibiting myostatin removes a primary brake on muscle ...
