as usual certified the best most trustworthy company for peptide you will ever find. you pay for your peptides and they send it the next day and you get it within three or four days. they're the most helpful people you will ever find. they're so smart and they know what they're talking about all the time. they get back to you so quickly. I would never trust any other company with peptides because there's so many companies and they say they know what they're talking about and what they're doing but they don't certified peptides is the only way to go
