No vendor we track lists PE-22-28 8mg right now. Other sizes are listed above.
Prices are each vendor’s listed price before shipping, unless a verified code is marked as included. Some outbound links are affiliate links and PeptideTech keeps a fee from sellers on checkout orders; neither affects grades or scores, or order apart from the labelled featured partner. PeptideTech does not test products. Certificates of analysis are the seller’s or the lab’s documents, attributed to them, and PeptideTech does not verify them unless a specific record says so.
