Thank you for the useful information. Tell me, if the buildup of muscle mass happened thanks to supplements, can the indicators of muscle mass be calculated according to the same scheme? I was excessively thin for a long time, even though I trained at the gym regularly and monitored my diet. But it was not possible to build muscle mass. Then my friend from the gym told me he knew the best place to buy sarms online, and I decided to try it. I have the best body shape I've ever had, but I'm worried about whether such muscle buildup is the norm. By the way, I have no side effects or deterioration in my health.
