Evidence summary
OptPeptides COAs and evidence
OptPeptides scores 6.5/10. Two named-client Janoshik reports support exact 10 mg products; broader certificate coverage, an identified legal operator and independent fulfillment history remain limited.
01
COA coverage and testing
Two complete reports match specific Janoshik Analytical records and identify OptPeptides as client and OptPeptides Global / OptPeptides.com as manufacturer. Each includes compound identification, numerical purity and measured content plus an attached sample photograph. Analysis was conducted January 9, 2026. The full public archive covers GLP-3R 10 mg and GLP-2T 10 mg; the other 11 current strengths have no posted exact report. No endotoxin, metals or sterility result appears in these two reports.
02
Purity and content results
GLP-3R 10 mg, batch OP-RET-0125, reports 10.30 mg content and 99.114% purity. GLP-2T 10 mg, batch OP-TIR-0125, reports 12.99 mg content and 99.768% purity. The nominal strength remains 10 mg in each record. The storefront posts the 10 mg certificates on product pages with larger options; those reports do not verify the 20 mg or 30 mg options. Both complete documents and official records are available in the COA library.
03
Customer history
The domain was registered September 16, 2025. Searches on October 11, 2026 found no attributable independent customer-review corpus on Trustpilot, Reddit or the signed-in Peptide Critic community. Third-party comparison listings establish catalog visibility, not customer fulfillment experience. The site’s claims of worldwide institutional reach and a PhD team do not identify customer accounts or named scientists.
04
Payments, shipping and returns
U.S. checkout offered credit/debit cards, Apple Pay and Link through Stripe. Standard delivery was stated as 1–3 business days at $14.99, with an additional $20 customs/import fee. The storefront advertises free shipping over $250 and international service. Terms target processing within 24–48 hours of payment. Change-of-mind returns are final; damaged items must be reported within 48 hours, with refund or replacement support for substantiated purity failures. The hosted checkout uses the merchant label Bloxie. Its first-order referral offer is separate from the current single-vial prices and cannot combine with bundle deals.
05
Business identity
The site identifies the brand as OptPeptide / OptPeptides and says it launched publicly in 2026. Its contact page says it is relocating and gives no physical office address. The reports name OptPeptides Global / OptPeptides.com as manufacturer. No registered operating entity, named owner or named scientist was established. Authoritative RDAP records September 16, 2025 registration, before the December 2025 testing orders and January 2026 analyses. The merchant’s stated 2022 research beginnings have not been independently established.
