Basically Tamoxifen from Novartis is a drug that was developed to fight against breast cancer by aromatization inhibition. It is usually used as part of aggressive treatment in post-menopausal women, to fight and reverse the spread of breast cancer after other treatments have failed (such as tamoxifen therapy). It is probably the most effective product on the market for this purpose currently, it is very similar in structure and action to its predecessor arimidex.
Tamoxifen is also and above all of particular interest to bodybuilders and athletes. First of all, proven to reduce estrogen levels by 98% or more. This is obviously of huge interest to bodybuilders. In effect, less estrogen in the body eliminates side effects of steroids such as water retention, gynecomastia, and acne. This makes Tamoxifen one of the best anti-estrogens on the market, even for very difficult cycles. Also, if you are doing bodybuilding competitions Tamoxifen helps to have lean, streaky muscle. The effective dose for Tamoxifen is 2.5 to 5mg per day. If you exceed this dose, there may be a risk of loss of libido. Also if you keep your estrogen levels too low for too long you will end up weakening your immune system.
It should be noted that Tamoxifen can also be used in post-cycle therapy to revive.Indeed Tamoxifen increases LH and FSH (which are hormones that trigger your testes to produce more testosterone) Tamoxifen is 2 to 5 times more potent than anastrozole (arimidex), and lasts a long time in the body, but takes a while to cast. You need to take Tamoxifen for 60 days to get your blood plasma levels back in balance. Even more impressive, Tamoxifen can reduce or eliminate an existing gynocomastia back ! In conclusion, Tamoxifen is a complete anti-estrogen that protects during and revives after the cycle, it eliminates the negative effects of steroids while providing an aesthetic advantage on muscle quality.
