Mate the customer service is awesome. I had a problem with one of my deliveries so they send me double for the same price. Will definitely be back

Ordered over a £120 worth of peptides when they had a deal on and never received anything

Purchased a one-month supply of peptides for $300, which was delivered with absolutely no instructions. The email and website both refer to a support line, but nobody responds to texts or emails. The website looks good at first glance; however, none of the links to the videos explaining how to mix, administer or store the peptides actually work. Overall, I would not recommend this company to anyone. The customer service is atrocious, and the whole experience has been an absolute waste of $299.

Ive been on peptides for over a year and recently lost my supplier and tried peak because they promised authentic peptides but they are weak and trash... I would never order from this place ! Youre pretty much just doing BAC water... find a place that sells quality peptides
