We have a sample submitted by muscletek labs for their sustanon 400. This was not a raw sample, this was a finished product and we found that it was, indeed, 400mg/ml. Sustanon is a blend of 4 different types of Testosterone all with different half lives. And they include Test P, Test Ph, Test I, and Test Deca. Typically when we test a sustanon product we only tell people that the substances are present. The reason for this is because if you have 3 different purity numbers.....say 10, 20, and 30 then what is the purity of the product? They can't be averaged, they can't be added together. So the only true way to know is to run each one independently. Well that is cost prohibitive. That is 4 different runs on the Q-TOF machine. But Quadfather paid to have each one analyzed. Which is why we have an 11 page lab test result. He wanted to know exactly what his compounds were made of. Here is what we found:

Test P: 8% and 62mg/ml
Test PH: 17% and 95mg/ml
Test I: 17% and 95mg/ml
Test D: 39% and 150mg/ml

The lab has it at 87% purity overall. So when you look at each one individually the purity signifies low, but it has to be taken in context with the rest of the product. These purity values are dependent on one another whereas normally we are only looking at one purity value which is independent of anything else. Bottom line is this is a very high quality product.
