Roxies Test E250mg/ml and Tren E 200mg/ml. The Test I can vouch for. Currently running it along side with Balkan Sustamed, which I am using for the first four weeks in current cycle(the sustamed) due to the fast acting esters, then will continue the rest of the cycle with Roxies Test. The Test is smooth and no problems using 23gauge 1.5" pin in glutes, no PIP, and is extremely clear. Would definatly order again. The Tren I let a buddy use 5mls of one of the bottles till his tren got in. Loves it, wishes he would have ordered Roxies Tren from the get-go. Thanks for an amazing Product!!
