Phiogen sets the bar for transparent peptide retail in the United States. Every SKU page lists chemical identity, CAS number, vial weight, reconstitution guidance, and a third-party HPLC purity certificate from the current production batch. Pricing is straightforward (no anchor-and-discount tactics) and shipping is consistent.

- US fulfillment with consistent 2-5 day delivery

Cons
