First off, forget the toremifene. This is a drug which i would not recommend outside of short term use for PCT or gyno.
By itself, androstenetrione will lower estrogen and raise testosterone levels. With DHEA, the testosterone boosting effects androstenetrione may be synergisticly increased. Yet, this estrogen depleted state is not healthy for long periods of time. Cycles of 4-6 weeks is as long as i would go if you decide to use an AI to raise testosterone.
Try some natural testosterone promoting supplements first. ZMA is were i would begin. Fenugreek is an inexpensive and fairly effective consideration. Alpha Drive is on sale at nutraplanet for like 10 bucks too. Ohh, I have heard nothing but positive feedback about Drive by rpn. So that may be a good option for you as well.:thumbsup:
