In my opinion, in most cases, I would combine an injectable and an oral before 2 using injectables.
So, for me, it is Primo & Var before Primo & Mast. Why? There are several reasons, but one of the reasons I am selecting Primo & Var over Primo & Mast is because you can add an anti-estrogen to your pre-contest cycle very cheaply. One of the primay ways by which Mast helps the user achieve a dry look is through its anti-estrogenic activity. If you add in an AI, there is no need for Mast's anti-estrogenic effect. On the other hand, Var does a great job of increasing muscle hardness and provides that grainy look without having to rely on anti-estrogenic activity. Remember, Primo also has anti-estrogenic activity...not as pronounced as Mast, but it is still significant. By using Primo & Var, each drug will provide benefits through different mechanisms.
