Verified peptide sources, COAs, vendors, labs, batches, and prices.
What's actually on file: 3,284 independent COAs linked to peptide, lab, batch, and date. We catalog the evidence. You decide.
Pick where to start
Each peptide class has its own evidence pattern — which labs cover it, how recent the COAs are, where the data runs thin.
GLP-1 / Metabolic
GLP-1 receptor agonists and related metabolic / weight-management peptides.
Growth Hormone Secretagogues
GHRH analogues and GHS-R agonists (CJC-1295, Ipamorelin, MK-677, etc.).
Healing & Recovery
Peptides studied for tissue repair, wound healing, and recovery from injury.
Immune Modulator
Thymic and immune-modulating peptides.
Melanocortin
Melanocortin receptor agonists (Melanotan II, PT-141, etc.).
Nootropic / Cognitive
Peptides studied for neuroprotection, cognition, and CNS effects.
Recently verified COAs
Independent third-party tests as they land — counted and refreshed daily, not a frozen snapshot.

AI-assisted Subtyping-directed Precision Treatment in Acute Aortic Dissection
Aortic dissection has acute onset and high mortality, with immunoinflammatory response driving lesion progression. Current perioperative anti-inflammatory therapies are mostly empirical and poorly targeted, and AI-assisted typing lacks a complete clinical translation pathway.

Product Transference Study of Testagen™ TDS®-Testosterone
This study will assess the potential of Testagen® TDS-Testosterone to enable transfer of Testosterone to females coming in contact with skin to which Testagen® TDS-Testosterone has been applied and the potential of product to raise serum androgen levels in those women.

vCA1 SST neurons represent avoidance states that guide anxiety-related behavioral choices
In uncertain, threatening environments, rapid and flexible behavioral decisions are essential for survival. The ventral CA1 region of the hippocampus encodes threatening contexts and can regulate avoidance-related behaviors.
