===================== VISIT OUR ONLINE STORE: https://t.co/XPoUmVhnz3 ===================== Test 400 is a blend of a few testosterone types. There are different types of it, but typically it includes a blend of three of the following: Testosterone Propionate, Testosterone Cypionate (Test C), and Testosterone Enanthate (Test E), Testosterone Isocaproate, Testosterone Phenylpropionate, and sometimes Testosterone Deconoate. For a beginner 400 mg of testosterone should be about a weeks dose. Since it's a blend, it contains Testosterone Propionate, which is a short-acting ester, so it should be injected 2x/week, e.g. half of the vial (200 mg) on Monday and the other half on Thursday.
