Valar Peptides
Selected for unusually broad public product-level COA coverage and clear batch documentation.
U.S. manufacturing claimed; legal entity and facility location not disclosed on reviewed pages
- Documentation
- Public product-level COAs found on 30 of 36 catalog pages checked
- Audience
- Research and development customers
- RUO language
- The site states that all products are for research and development use only, not for human consumption, and that Valar Peptides is not a 503A/503B compounding or outsourcing facility.
- Testing claims
- Public product-page COAs reviewed include a batch or lot number, analysis date, HPLC identity and purity results, measured peptide quantity, endotoxin result, instrument listing, and QC authorization. The supplier separately claims mass-spectrometry confirmation and third-party verification.
Profile status: Editor's Choice — official public batch documents reviewed
The requested valarresearch.com domain did not resolve and had no .com registry record when checked; the operating site found was valarpeptides.com. On July 10, 2026, 30 of the 36 products linked from its catalog had working public COA PDFs; AOD-9604, Hexarelin, NAD+, Oxytocin, Pinealon capsules, and Tirzepatide stated that no COA was available yet. The reviewed COAs name a Valar QC authorizer but not an independent laboratory, so they substantiate public batch documentation without independently verifying the site's third-party-testing claim. 'GMP comparable' is not evidence of GMP certification; the terms select UAE law while the site claims U.S. manufacturing.
