Tesamorelin + Ipamorelin

No COA and ignores emails requesting COA

This was my first peptide purchase, and it ended up being a real learning experience. On April 29, 2026, I ordered five vials of their 2X Blend (Tesamorelin 10mg / Ipamorelin 5mg) Research Blend.

The vendor lists COAs on their website, and I made the mistake of assuming the most recent one matched my order. It didn’t. Their latest published COA for this blend is from July 2025, while the vial I received was from lot 2X12A013026, which has no COA on file at all.

Separately, I also had a shipping address issue. I emailed support about that and they responded immediately and fixed it without any hassle. But when I followed up about the missing COA, I got nothing… no reply at all.

Given the total lack of response on a basic quality/testing question, I can’t recommend this vendor.
