Featured Peptide Profiles
Semaglutide
An approved GLP-1 receptor agonist with a fatty-acid modification for once-weekly dosing in type 2 diabetes and chronic weight management.
Read profile →02Tirzepatide
An approved dual GIP and GLP-1 receptor agonist peptide for type 2 diabetes and obesity, given by once-weekly injection.
Read profile →03Retatrutide
An investigational single peptide designed as a triple agonist of the GLP-1, GIP, and glucagon receptors for obesity and metabolic disease.
Read profile →04Cagrilintide
Long-acting synthetic amylin analog in clinical development for obesity, often studied with semaglutide as the combination referred to as CagriSema.
Read profile →05BPC-157
Synthetic pentadecapeptide derived from a human gastric-juice protein, studied mainly in rodent models for tissue protection and accelerated healing.
Read profile →06TB-500
The research-market name for synthetic thymosin beta-4, an actin-regulating peptide with broad wound-healing and repair literature.
Read profile →07KLOW (Lys-Pro-Val Complex)
Vendor-defined name used inconsistently for KPV or for multi-peptide blends; no peer-reviewed literature on KLOW itself.
Read profile →08GLOW (GHK-Cu / BPC-157 / TB-500 Blend)
Supplier-formulated three-peptide combination (GHK-Cu, BPC-157, TB-500) with no published studies of the blend itself.
Read profile →09Ipamorelin
Pentapeptide growth hormone secretagogue with high selectivity for GH release; commonly used in GH-axis research protocols.
Read profile →10Tesamorelin
A synthetic GHRH analog approved for HIV-associated lipodystrophy to reduce visceral abdominal fat via restored endogenous GH secretion.
Read profile →11GHK-Cu (Copper Peptide)
Naturally occurring copper-binding tripeptide (glycyl-histidyl-lysine) studied for skin remodeling, wound healing, and tissue-repair signaling.
Read profile →12MOTS-c
16-amino-acid mitochondrial-derived peptide encoded in mitochondrial 12S rRNA; studied for metabolic regulation in rodents.

Ultimate Sourcing Guide
The full pipeline: how to evaluate vendors, what questions to ask, what tests actually matter, and how to protect yourself from the 90% of the market that is trash.
Open guide →COA Analysis & Interpretation
Certificates of analysis are the single most gamed document in this industry. Learn to read the data — not the logo — and spot the difference between a real HPLC trace and a PDF.
Open guide →Vendor Red Flags
The warning signs we catalogued across years of vendor reviews — from fake lab logos to "sterile" claims with zero evidence.
Open guide →BAC Water vs Sterile Water
When bacteriostatic water makes sense, when it doesn't, and why the multi-dose question is a contamination question first.
Open guide →Trusted Source Database
Vendor-grade, independently re-tested sources with batch-level data — verified members only. No shills, no paid placements.
View sources →FDA-Approved Peptides
The short, frequently misunderstood list of peptides with actual regulatory approval — and why "peptide" alone is not a safety signal.
