Peptide Research Library
One canonical, referenced page per compound. Each entry sets out identifiers, the proposed mechanism separated by study type, a table of published studies, the limitations of that evidence, and links to primary sources.
These pages summarise published scientific literature for laboratory professionals. They are not medical advice and do not describe human or veterinary use. All materials supplied by Peptide Pilots are for controlled laboratory research only.
Semaglutide
What does published research show about how semaglutide interacts with the GLP-1 receptor, and how strong is that evidence?
Read the overviewTirzepatide
What is the published evidence that dual GIP and GLP-1 receptor activation behaves differently from GLP-1 receptor activation alone?
Read the overviewRetatrutide
What is currently established about retatrutide's receptor pharmacology, and how mature is the published evidence?
Read the overviewMOTS-c
What has been published about MOTS-c's mechanism and metabolic effects, and how far does the evidence extend into humans?
Read the overviewAOD-9604
What was AOD-9604 designed to do, and what did its published mechanistic and clinical studies find?
Read the overviewBPC-157
What does the published literature actually establish about BPC-157, and is there any human evidence?
Read the overviewTB-500 (thymosin β4 fragment)
How does TB-500 relate to thymosin β4, and which repair-related findings come from the fragment rather than the full protein?
Read the overviewKPV
What is the evidence that the tripeptide KPV has anti-inflammatory activity, and where does that evidence come from?
Read the overviewThymosin alpha-1
What is thymosin alpha-1's proposed immunological mechanism, and what does its clinical trial and regulatory record actually show?
Read the overviewGHK-Cu
What is the published basis for GHK-Cu's activity, and how much of it comes from controlled human studies?
Read the overviewNAD+ (nicotinamide adenine dinucleotide)
What does published research establish about NAD+ biology, and what do human precursor trials actually show?
Read the overviewSS-31 (Elamipretide)
What has SS-31 (elamipretide) actually shown in human trials, and where has it fallen short of its endpoints?
Read the overviewEpithalon
What is the evidentiary basis for Epithalon's reputation as a longevity-related peptide, and how independent is that literature?
Read the overviewIpamorelin
What made ipamorelin scientifically distinct among growth hormone secretagogues, and what happened to its clinical development?
Read the overviewCJC-1295 (no DAC)
How does CJC-1295 without DAC differ from the original long-acting CJC-1295, and what does the published pharmacology show?
Read the overviewTesamorelin
What is the strongest published evidence for tesamorelin, and which endpoints does it actually cover?
Read the overviewSermorelin
What is sermorelin's mechanism, and what does its clinical trial and regulatory history actually establish?
Read the overviewIGF-1 LR3
What is the published evidence behind IGF-1 LR3, and how does it differ from native IGF-1?
Read the overviewKisspeptin-10
What has controlled human research established about Kisspeptin-10's effect on the reproductive hormone axis?
Read the overviewPT-141 (Bremelanotide)
What is the controlled human evidence behind PT-141, and what were the safety findings that shaped its approved use?
Read the overviewGonadorelin
What does the published literature establish about gonadorelin's effects, and why does dosing pattern matter so much for interpreting it?
Read the overviewOxytocin
What does published research establish about oxytocin's central and peripheral actions, and how reliable is the human intranasal literature?
Read the overviewMelanotan II
What does published research establish about Melanotan II's melanocortin receptor activity, and what do regulators say about its unsupervised use?
Read the overviewSemax
What does published research establish about Semax's mechanism and clinical evidence, and how geographically limited is that evidence?
Read the overviewSelank
What does published research establish about Selank's mechanism and clinical evidence, and how geographically limited is that evidence?
Read the overviewDelta Sleep-Inducing Peptide (DSIP)
What does published research establish about DSIP's mechanism, and how consistent is the human evidence that it promotes sleep?
