SuppVersity - Nutrition and Exercise Science for Everyone: Ecdysterone: Supplemental Non-Starter or Estrogen-...: Estrogens are not for women, only!? If you asked me the above question a day ago, I would have answered "supplemental non-starter
Bottom line: Overall the study at hand is unquestionably the most convincing evidence of the muscle building effects of ecdysterone I've seen. On the other hand, the mere fact that no one reports similar gains on any of the currently or previously available ecdysterone supplements should make you question, whether popping 60-75mg of >90% pure ecydesterone, which would be the human equivalent of the dosage the rodents received in the study at hand, will really make you big and strong. Why? Well because the fiber-size of the soleus increased without increases in soleus weight (control: 0.16g; ecy: 0.15g) -- If you expect internal changes in muscle structure, only, go for it, if you want gains, I stick to what I said before: Avoid ecdysterone supplements.
