1. tested a sample that had already been tested by another lab - came back purity of 99% vs other lab 99.9% purity. asked for test to be confirmed as 49 other tests over 8 months lowest purity was 99.6%. crickets. 2. 14 days after they received my samples on a different test. Crickets. That's way, way too long. Very VERY disappointed with this lab.

I have ordered PEPTIDES for going on four years. I have used multiple labs. And I have to say with 100% assurity, this is one of the best labs I have you’ve ever used. Not only do they give me purity, they give me true volume, and they verify if what is in the vial is what I was told it was. I just sent in RETA 60 mg, and they saved me by letting me know that none of it was RETA at all. Not even a smidgen. It was all filler. I will always be grateful to BT Labs for their hard work
