Optimum Formula
Optimum Formula describes itself as Southern California-based and publishes a support email, shipping policy, returns policy, and research-use terms. The public site did not identify an owner, legal entity, or street address during this review. The member FAQ lists credit and debit cards, cryptocurrency, and alternative or manual-invoice options when available. Retail shipping is domestic; the site says international wholesale may be available by inquiry. Affiliate status does not affect the rating.
The public COA page exposed 73 unique report assets during the August 14, 2026 review. PeptidePrices inspected current ILS Labs certificates for BPC-157 10mg batch HX4RRT (COA-2026-9QVTTY), Retatrutide 30mg batch HX3ZU (COA-2026-RA1YLR), Selank 10mg batch HXAC8 (COA-2026-412951), and Tesofensine 500mcg lot 001 (COA-2026-954735). The first three report identity, HPLC purity, measured content, PCR no-growth screening, and endotoxin results. The Tesofensine capsule report has a different scope: identity, purity, measured content, fentanyl screening, and four-sample conformity. ILS describes its PCR screen as a rapid microbial-DNA screen, so PeptidePrices does not present it as a classic 14-day compendial sterility test.
The current independent reputation record is useful but not mature. An exact-domain Reddit thread contains repeat-order, fast-shipping, and responsive-support reports alongside multiple complaints about delayed email responses. Anonymous comments are anecdotal and do not verify product composition. No exact-domain Trustpilot profile was found; the prominent Trustpilot result in review searches belongs to liveoptimum.co, a different business. Automated website-risk scores are also not customer reviews or laboratory evidence.
