Need your tips and advice when it comes to using tren. I've currently used masteron along with primo and I'm not getting the type of results I've been asking for. I would like to switch out the masteron and add in tren instead. Do you think 500 mg of primo and 400 mg of tren would be a good stack together for a recomposition? I'm currently 47 years old, 5 ft 10, and around 105 kg.
