Tamoximed (Tamoxifen, Nolvadex) is one of the safest anti-estrogen drugs that is currently used by athletes and bodybuilders. It prevents the aromatization of testosterone based steroids and the development of gynecomastia.
For the purpose of estrogenic side effect protection during anabolic steroid use, 10-20mg per day is common. For post cycle therapy standard Nolvadex doses will normally begin at 40mg per day. The dose will normally hold at 40mg per day for a couple weeks, reduce to 20mg per day for a couple weeks and then finish with an optional week or two at 10mg per day. How your cycle ends will determine when you begin your Nolvadex therapy. If HCG is included, this will also affect the timing.
When to use:
Tamoxifen is indispensable during and after a medium to heavy cycle. Make sure you include it as a staple in your anabolic medication. It can be used for a light cycle as well but in that case Clomed is more recommended.
