no real issues
Samantha D. reviewed Research Peptides

Ordered the GHK-Cu, arrived in about a week, vials crimped clean. Cold pack was a little soft on arrival but the order itself was fine.

fourth order, still smooth
Penelope S. reviewed BuyDeus

Been ordering from BuyDeus since late last year and this was my fourth box. TB-500 and a couple of Ipamorelin vials, all carefully wrapped, all filled to the line. Support answered a stock question within a day. EU domestic delivery has been quick every single time. No drama, which is exactly what I want from a vendor.

good pricing
Benjamin V. reviewed US Peptide Labs

Per-mg pricing on their BPC-157 is noticeably better than the two vendors I used before, and it didn't feel like a quality compromise. COA checked out.
