Mechanism
Each peptide in the catalog targets a distinct pharmacological pathway: GLP-1 / GIP / glucagon receptor agonism (Retatrutide, Tirzepatide), VEGFR2 and gut-mucosa pathways (BPC-157), actin polymerization and angiogenesis (TB-500), copper-binding fibroblast modulation (GHK-Cu), mitochondrial NAD+ availability (NAD+, MOTS-c), and NNMT inhibition (5-Amino-1MQ). Browse the full catalog at /research-peptides for individual mechanism summaries.
Research summary
Across our blog you will find 2026-current research summaries for every peptide in the catalog — including the GLP-1 dementia real-world evidence review, the SURPASS-CVOT cardiovascular outcomes summary, the Retatrutide TRANSCEND-T2D-1 Phase 3 readout, and the multi-peptide wound-healing review.
Research dosing reference
Reconstitution, storage, and dosing references for every peptide are published at /peptide-info.
Research stacks
Common research stacks include Wolverine (BPC-157 + TB-500), Glow (GHK-Cu + BPC-157 + TB-500), and Metabolic (Retatrutide + AOD-9604 + 5-Amino-1MQ).
Purity and COA verification
Every batch of every peptide we sell we ship is independently verified by an ISO 17025 third-party laboratory. Identity is confirmed by mass spectrometry, purity is measured by reversed-phase HPLC, and endotoxin and bioburden testing protect the integrity of your research samples. We never accept stock without a fresh, batch-specific Certificate of Analysis on file, and the COA travels with the vial — printed on the box label and emailed with your order. Vials are filled in a Class 7 cleanroom, lyophilized to a stable cake, sealed under vacuum, and shipped in temperature-controlled packaging so the compound that arrives at your bench matches the certificate down to the decimal point.
Shipping and support
Orders placed before 2:00 PM ET ship the same business day from our USA facility. Standard delivery lands in 2–4 business days; expedited and priority options are available at checkout. Every order over $300 ships free, and we use insulated packaging with a cold pack for temperature-sensitive compounds. If anything arrives damaged or off-spec we replace it — no restocking fees, no upsell. Customer support is human-staffed and replies to research and order emails in under one hour during business days.
