is it possible that nolvadex, by it self, at 20mg/day might be able to raise natural testosternoe production? Or just helps us to get rid of some water?
"Nolvadex and Muscle Definition
Within 24 to 48 hours, Nolvadex is able to greatly increase muscular definition. As a result, bodybuilders assume Nolvadex will help them reduce their bodyfat level. But this rapid cutting action of Nolvadex is due to an anti-estrogenic action on water retention. Estrogens will make you hold water. Nolvadex will produce the opposite effect. But it says nothing about the impact of Tamoxifen on bodyfat. Depending upon your own production of estrogens and your estrogen receptor density on adipocytes, Nolvadex can act as an antagonist (which would help you lose fat) or an agonist. In that case, Nolvadex will make you fatter especially in the lower body area.
Conclusion: if the introduction of Nolvadex 25 years ago was a brilliant idea, times have changed. Very effective anti-aromatase drugs (such as Letrozole or Anastrazole) have been introduced. They will fight gynecomastia, help prevent the anti-anabolic actions of estrogens, fight fat and water retention. They will also boost natural testosterone production far more effectively than Nolvadex. So, it is up to you to decide whether you wish impair your rate of progression with an outdated drug or move on to the 21st century."
