Hardly a day goes by without more research being announced into peptides and their usage. In the following pages you will find everything you need to know about Peptides and what they are being used for. Please remember this site is not Medical advice, please consult with your medical professional before making any deisions on your own health.
Use this chart to compare the main research areas linked to popular peptides and related compounds. A green tick means the compound has been researched, studied, or commonly discussed in connection with that area. This does not mean the compound is approved, safe, effective, or recommended for use.
Important note: This chart is for educational and research-information purposes only. A tick means the peptide or compound has been researched, studied, or commonly discussed in connection with that area. It does not mean the compound is approved, safe, effective, or recommended for use.
| Group | Peptides | Why they’re associated |
|---|---|---|
| GLP-1 / incretin / weight-management peptides | Semaglutide, Tirzepatide, Retatrutide | Closely related metabolic drugs. Semaglutide is a GLP-1 receptor agonist; tirzepatide targets GIP + GLP-1; retatrutide targets GIP + GLP-1 + glucagon. (FDA Access Data) |
| Fat metabolism / metabolic-energy peptides | AOD-9604, MOTS-c, NAD+ | AOD-9604 is a human growth-hormone fragment associated with lipolysis research; MOTS-c is a mitochondrial-derived peptide linked to glucose/metabolic regulation; NAD+ is not a peptide, but is often grouped with metabolic/mitochondrial protocols. (PubMed) |
| Growth hormone secretagogues / GH–IGF axis | CJC-1295 with DAC, Sermorelin, Tesamorelin, Ipamorelin, GHRP-6, Hexarelin | These are associated because they stimulate or mimic upstream signals for growth hormone release. Sermorelin/CJC-1295/Tesamorelin are GHRH/GHRF-type; Ipamorelin, GHRP-6 and Hexarelin are GHRP/ghrelin-receptor-type secretagogues. (PMC) |
| IGF / muscle-repair / anabolic signalling | IGF-1 LR3, PEG-MGF, Follistatin-344 | These are often grouped around muscle growth, repair, hypertrophy or anabolic signalling. IGF-1 LR3 and PEG-MGF relate to the IGF/mechano-growth-factor family; Follistatin-344 is usually associated with myostatin/activin inhibition rather than GH release. |
| Tissue repair / wound healing / collagen / injury-recovery cluster | BPC-157, TB-500 / Thymosin Beta-4, GHK-Cu, KPV, LL-37 | Commonly grouped around tissue repair, wound healing, angiogenesis, inflammation control, collagen or antimicrobial defence. Thymosin beta-4 has wound-healing literature; reviews also discuss BPC-157, TB-500 and GHK-Cu together in tissue-repair contexts. (PubMed) |
| Immune / antimicrobial / anti-inflammatory peptides | Thymosin Alpha-1, LL-37, KPV, TB-500 / Thymosin Beta-4, BPC-157 | These are associated with immune modulation, inflammation or host-defence pathways. LL-37 is especially antimicrobial/host-defence; KPV is usually discussed as anti-inflammatory; Thymosin Alpha-1 is usually grouped as immune-modulating. |
| Neuro / mood / cognition / sleep peptides | Selank, Semax, DSIP, Epitalon | These are often grouped as neuropeptides or CNS-associated peptides. Selank and Semax are commonly paired; DSIP is sleep-associated; Epitalon is usually placed in longevity/circadian/telomere-adjacent discussions rather than classic cognition. Selank has literature showing effects on neurotransmission-related gene expression. (PubMed) |
| Sexual function / melanocortin pathway | PT-141 / Bremelanotide, Melanotan II | Strongly associated through the melanocortin receptor family. Bremelanotide/PT-141 is a melanocortin receptor agonist; Melanotan II is also melanocortin-related and commonly associated with tanning/sexual-function discussions. (FDA Access Data) |
| Reproductive hormone axis | Kisspeptin-10 | Best grouped separately. Kisspeptin acts upstream of GnRH and stimulates gonadotropin/LH release, so it belongs to the reproductive endocrine axis rather than GH or GLP-1 families. (PMC) |
