Counterfeiters are getting better and better at making their own amps and making them look exactly like the genuine product. They are getting so good that often times it is impossible to tell the difference by just looking at them.
So what are we to do? well I'm going to share two brands of test that there are zero counterfeits of right now! this is probably due to the unpopular dosages of the testosterone but if you don't mind injecting a few more ML's per week you can almost guarantee yourself that you have 100% legit human grade test.
Jelfa Test Prolongatum 100mg amps or the 100mg version of Testoviron Depot are both safe bets!
