With this product i had amazing results.In the end i ended up gaining 12 lbs of lean muscle. After PCT i kept 10 lbs which i found astonishing. Not only did I get muscle mass with this product but my strength skyrocketed ( for example my bench press went from 205 to 245). Something that i really like about this product was also that i experienced no side effect not even dome acne. So overall i was really satisfied with this product and i will definetly use it again in the future. i recommend it to anyone who wants to gain lean muscle mass with no sides effects. On a side note if you use this product make sure you plan out a proper PCT.
