Pacific Research Labs

Ordered Semax and KPV together. Semax arrived fine but KPV vial had a small crack in the rubber stopper. Contacted them and they shipped a replacement but it took 8 days total to resolve. The actual peptides tested well once I got usable vials. Wish their QC caught the defect before shipping.

This is my third order of BPC-157 from Pacific Research Labs and they've been consistent every time. The COA shows 98.7% purity which is what I need for my protocols. They include bacteriostatic water which is convenient. Shipping took 5 days but that's reasonable. Only gripe is their website checkout process is a bit clunky - had to re-enter payment info twice. Product quality makes up for the minor inconvenience though. Their batch testing documentation is thorough and they clearly take quality control seriously.

Bought CJC-1295 and GHK-Cu as a bundle during their holiday sale. Both products came with individual COAs dated within the last month. The GHK-Cu had a beautiful blue tint which indicates proper copper binding. CJC reconstituted smoothly with no particulates. Their packaging uses pharmaceutical-grade vials with crisp labels. Customer service answered my dosing calculation question within a few hours. Prices are middle-of-the-road but quality seems worth it. Tracking was accurate and delivery was on schedule.
