5.00/5 | Reviewed November 16, 2025 Peptide: IGF-1 LR3 I recently ordered from Penguin Peptides because my "usual" vendor was out of the particular item I wanted. I was a bit hesitant at first but im glad I orded from them. They were prompt, my order was correct AND they included some Penguin Peptide swag with my order. Other people seem to really like them as well. I WILL BE ordering from them again for sure. View original review on PeptideCritic Reply below to discuss this review or ask the reviewer questions.

5.00/5 | Reviewed November 14, 2025 Peptide: GLP2-T I purchased 21qty of the 50mg Tirz. I sent one vial out for my own testing and it came back at 53.6mg and 99.95% pure. Really great results. The owner of this company was very responsive to my questions and sent lots of free goodies with my order. However, I will say that there are no batch numbers on the vials. Also, the owner told me that they don't sample test each and every batch due to cost. This is the reason I sent one of my vials out for my own testing, just for piece of mind. I do think this is a great vendor and I would recommend. I just hope they're able to start printing batch numbers on the vials and performing sample tests of each batch in the future.
