Great group of owners, local to the Houston area, easy to use website and pay options, super fast delivery (most orders show up in 24 hours) and they run specials and promotions all the time. I have turned so many people on to Peak Force Labs. Thank yall so much.

The product is absolutely amazing. I’ve other numerous times and only had one product issue and it was resolved immediately. I have had another issue of sorts, I had a question regarding points spent so I called and left a message and have yet to receive a call back. Bummer on an otherwise great experience. My issue with the points program is this . I’ve accumulated over 77,000 points but I can only spent 1000 points per order. It may very well be something I’m doing wrong which is why I called. 🤷🏻♂️ I’ll still order as I get short on product and time. This is still my go to US supplier.

Shipping has been very quick! Smooth check out process and my coworker had to send a email for a question and it was replied to within 30-1 hour. We order GLP-T and the fast shipping is helped our research keep up. So far we are seeing excellent results as well. Thank you PFL!!!

It was nice to get a first purchase discount. Shipping took a while and was not able to get it shipped in a insulated container with a cold pack wish that was a option as I live in Arizona where it’s very hot and don’t want the peptides to spoil prior to arrival
