FAQ
Questions buyers ask when switching supplier.
What happened to Peptide Sciences and Science.bio?
Science.bio closed in January 2026 and Peptide Sciences closed in March 2026. Amino Asylum was raided in 2025. Many other vendors pulled their GLP-1 lines under compliance pressure after FDA closed the regulated-pharmacy GLP-1 grace period in 2025. The B2B supply field consolidated quickly; the surviving suppliers are the place to re-source.
How is Pepti different from the typical research-peptide vendor?
Pepti is a B2B peptide manufacturer and private-label OEM facility for research organizations, brand owners, qualified B2B research buyers and research labs — not a consumer storefront. COA + HPLC + MS for the production lot; sample lots from a few vials before pilot or repeat orders. See quality & documentation.
Do you supply the GLP-1 family (semaglutide, tirzepatide, retatrutide)?
Yes — supplied worldwide as research peptides for qualified B2B and research buyers, and for private-label brand evaluation. Buyers confirm local regulatory compliance. CAS-traceable, COA + HPLC + MS for the production lot. See the GLP-1 2026 update.
