Solid combo stack, one hiccup
Willow Kemp

Ordered the CJC/Ipa blend and standalone Ipamorelin for my research protocol. Both came with COAs that checked out when I verified the batch numbers. Shipping took 6 days which was a bit longer than advertised but not terrible. The Ipamorelin vial had a small crack in the rubber stopper when it arrived - still usable but made me nervous. Customer service replaced it no questions asked within 48hrs. Quality seems legit based on reconstitution and clarity. Pricing is middle of the road. Would order again but hoping for better packaging next time.

Mixed feelings about this order
Griffin Stone

Got the CJC-1295/Ipamorelin combo after seeing good things online. The COA looked legitimate and purity numbers were decent at 98.3%. However the customer service experience was frustrating - took 3 days to get a response to a simple question about reconstitution volume. Shipping was actually pretty fast at 4 days. Product itself seems fine, dissolved clear with no particulates. My main gripe is the price point feels high for what you're getting compared to other vendors I've used. Not bad overall but not exceptional either. Probably won't be my go-to vendor moving forward.
