hmm I have never seen that b4. Did you get it from a local source or oveseas? it sais for lab use only? is this an UG lab? who knows bro. Test though is easy to know if its real or not. Test will always give you woodys and make you feel strong. if you have done test b4 you should be familiar with the effects it has on your body. give it some time maybe some1 else will know
