Xtreme mass (new formulation) is MethylStenbolone which is very similar to Superdrol. Xtreme DMZ is Dymethazine which is also very similar to Superdrol (a little bit weaker).
Staking both is a not a great idea. First, two are methylated so it’s a lot of stress on liver. Second, both are prohormones that CAN produces major side effects. Staking both might give you side effects that will outcome the potential good effects from them.
I think it would be better to do a one good cycle of Xtreme Mass alone or Xtreme DMZ alone.
Epistane (2a,3a-epithio-17a-methyl-5a-androstan-17b-ol ) is a PRO-anabolic antiestrogen which has been scientifically proven to REDUCE PREEXISTING GYNOCAMASTIA. As a PRO-Anabolic compound Epistane promotes increases in strength and lean body mass with an anabolic/androgenic value (Q ratio) of 12. With most powerful androgens there is a high risk of the natural suppression of the gonads. Epistane, unlike other PRO-Anabolic compounds that have recently been released, is relatively mild on the gonads and, due to the anti-estrogenic effects and the fact that Epistane keeps LH levels elevated, post cycle therapy becomes a breeze. All effects combined make Epistane a great compound to produce dry, lean gains in muscle mass with minimal side effects and suppression of the body’s natural androgen production, while lowering the effects of natural estrogen or combating estrogen from endogenous/exogenous sources. This makes it a powerful tool when combined with “wet” compounds in attempt to increase gains and decrease side effects.
