Here we have a mass spec lab test from Zewi and Mak of Eliteanabolx, and I must say that this product came in at an astounding 95% purity and I am truly impressed. This is one of the highest that we have seen if not the highest purity rating that we've seen from the Primo A. So much of this high dollar compound is counterfeited that many people have steered away from it except for old schoolers. Finding Good Primo is very difficult but it appears that these guys have mastered it. They continue to improve and it doesn't appear they are slowing down. Great work gentlemen letting people pin with confidence that they are getting a good product.
