Nice, the kid is huge. I'm certainly no expert, but I have looked into myostatin a bit. Apparently levels in the human body are at their peak within 8 weeks on cycle. The thought is that it inhibits our growth so we don't get too massive(*#@*%$#*) LOL. There are a few different thoughts out there to deal with it, one is to just push through, another is to add another compound to force through. I have looked for definitive answers on a few boards and different places but there are always 2 sides to every story. Some say it stops growth, others say even at peak levels there is still growth. We are all different, if I'm on short esters for 8-10 weeks I don't worry, but longer runs on long esters I will add another compound.
Some of my thoughts.
