Pharma Tech Labs’ Testosterone 400 is a blend of 3 different Testosterones. This blend is consistent of 150mg of Testosterone Enanthate, 150mg of Testosterone Cypionate and 100mg of Testosterone Decanoate. This is a perfect product for bulking and especially for those that tend to be using higher doses of Testosterone. The blend only contains long esters, so frequent injections are not warranted at all for this product. Products that contain a high amount of hormones in a single millimeter can cause post-injection discomfort to varying degrees for some users. Some users may experience no discomfort at all, while others may be sore for a day or two. This compound is mainly used by intermediate to experienced users.
