not as good as human grade but i have gotten good results from it in the past. i would recommend using more of it ex. 1.5 ml instead of 1 ml, even though it says it is overdosed on the site. also if you are going to use any form of the test make sure you mix it with an equal amount of either eq or deca (or whatever else you are shooting it with) or else you will have an extremely painful injection.
all that being said i will not be ordering any more any time soon.
