I ran this product at 50 mg per day for 40 days. I was running this along with 600 mg of test e. I leaned out considerably as the bloat from the test slowly disappeared. Due to that fact that after about week 6 of being on the test e I stopped gaining weight even though my diet was pretty heavy. I used the product from week 4-10 of a 12 week cycle. No noticeable increase in strength but that doesn't happen usually with Winstrol for me however my cardiovascular endurance did improved and I noticed I was able to push through reps a little bit better.
