I love Penguin Peptides

I love Penguin Peptides. They're a great company and even the free shipping is fantastic and very timely. They consistently over-delivery on what you're getting for your money, though the price is a fantastic deal anyway, and the speed with which they deliver is phenomenal. I never have to worry about there being a break in my research because I didn't get my materials in time. In addition, the customer service is helpful, quick to respond, and pleasant to work with. My research rats also love Penguin, and my rats and I agree that the results of the peptides seem to line up with what the research suggests they should. My rats and I look forward to our continued business with Penguin Peptides to supply our research.

Can’t go wrong with Penguin

Gary is totally Legit. I’ve had to have 2 returns (all my fault) and Gary has been true to his word in refunding me. On top of that, his peptides are also legit!! Thanks so much Gary!!

questioning authenticity

shipped fast, but didn't have any suggested dosing etc. also i bought the GLP3r. and i don't think that its going anything at all. So makes me question the authenticity of the other products. d
