MOTS-C and Reta
The MOTS-C kicks ass. Once my Reta from elsewhere runs out I’ve. Got some from here to test and based off the MOTS-C it’ll probably be great.

Mr.
Appreciative of the quality of the products(bpc 157, tb 500, hgh, reta, and melatanon 2) I am experiencing the hpoed for results of each peptide. Also, want to acknowledge the team at Peak for assistance in ordering and detailed shipping updates. All in all a 10/10 experience and I wholeheartedly recommend.

My legit experience
I’ve ordered a few times from this company and the first two were great. Zero complaints. Would have been 5 stars. However, the last time I ordered and did overnight shipping. UPS screwed something up and it took 5 days to get my order. (3 business days, 5 days in total) I emailed customer service about getting a refund on the shipping, or maybe an overnight credit for my next order since I received my order much later than I paid for…never heard back. Reviews show they have great customer. I’m not saying they don’t. .but wasn’t my experience because I never heard back. I will continue to order from the company as long as this doesn’t become a habit and is a one off thing.

Great experience after initial skepticism
I was skeptical at first (as I am of most of these sites) but I had a really good experience with Peak Labs. I emailed the company with a handful of my questions wanting to understand more about the quality of the product and the owner of the business got in touch with me directly with thorough responses. Placed my first order yesterday and already got a notification that it has been packed, which is also super reassuring.
