I would just stick with AX stack. If your really serious about using Prime, try stackin that with another usp labs product such as anabolic pump or p-slin. Also, do you have prior experience with prohormones? Make sure you researched what your taking... Granted, hyperdrol and mass fx are nowhere near superdrol or phera for that matter, however they will affect your hormonal balance somewhat and you need to know what your doing.
