COA
Every item on this page is a single compound in a single vial: BPC-157, TB-500, GHK-Cu, MOTS-C, SS-31, PT-141, MT1, MT2, kisspeptin-10, selank, semax, sermorelin, tesamorelin, IGF-1 LR3, cagrilintide, glutathione, NAD+, and the receptor-agonist compounds semaglutide, tirzepatide and GLP3-RT (retatrutide). Co-formulated multi-peptide vials are listed under Blends, and the diluent used to reconstitute any of them is under BAC Water.
A strength is a mass of lyophilized powder, not a concentration. Reconstitution does not change that mass — it changes the volume it occupies — so the concentration you end up with is set entirely by how much diluent you add. A 10mg vial taken up in 1mL is 10mg/mL; the same vial in 5mL is 2mg/mL. Eight compounds here are stocked at more than one strength: BPC-157, semax and selank at 5mg and 10mg, GHK-Cu at 50mg and 100mg, semaglutide and tirzepatide at 10mg and 20mg, glutathione at 600mg and 750mg, and GLP3-RT at 10, 20, 30 and 60mg. Each strength is stocked and documented separately, and each product page shows cost per mg so sizes compare directly.
Where identity could be verified against a public chemical record, the product page carries the CAS number, molecular formula, molecular weight and PubChem ID — and the molarity figures in that page's reconstitution table are calculated from that molecular weight. Where it could not be verified, the fields are left blank rather than filled with a plausible-looking value. GLP3-RT and IGF-1 LR3 are the two compounds here with no identity block; GHK-Cu carries a CAS number and formula but no PubChem link, because no PubChem record matches the neutral copper complex supplied.
A certificate reports identity, purity and composition for one batch: the lot it was issued against and no other, with the detail varying by compound and batch. That is what lot by lot means — a certificate is issued against material that was actually assayed, not against a product name. Where the certificate records a batch identifier it is on the document; several do not carry one. Each card in the grid above either links to the certificate for its current batch or is marked "COA pending publication." Not every compound in this catalog has one published. Where none is published, a certificate is available on request, as is a certificate covering a specific order or an older batch.
