Much like its longer estered version, Masteron E, this is a DHT derivative that offers all the same benefits of Masteron E, but in a shorter estered version. The half life is much shorter and can be beneficial for users leading up to competition or looking to get the gear out of their system more quickly at the end of a cycle. A great addition to any cycle!
Mast E is an injectable steroid. The usage of injection should be taken every other day without fail. As a start, 400 mg is enough for a week. Thinking of safety as the primary focus, consider only sterile needle usage.
