I just recently finished up a bottle. Results in, definitely some muscle hardening, and I estimate about a pound of lean body mass gain without much weight gain, I wasn't tracking my diet too strictly. Definitely felt a bit more aggressive, a bit more energy as well, I don't have to struggle to get out of bed every morning. Results were not as extreme as I'd hoped, I think my low total Test is moderating any gains I'd get from blocking aromatization. I'll be seeing an endo as soon as I can. Once I get that in order I'll be ordering another bottle, I think I would get much better results next time.
