A report cited a 24-year-old bodybuilder who allegedly gained 5 lbs in the first week of adding Follistatin 344 to an existing cycle of Test, NPP, Mast, IGF-1 LR3, and Peg-MGF. The user reportedly gained a total of 35 lbs over the full cycle, with over half of those gains attributed to the 8 weeks they were using Follistatin.
