Yes, I been studying genes for a while. In reality, Myostatin is just a muscle regulator or a gene regulator; it prohibits muscles from getting to big. In relation to muscle building, Myostatin is synonymous with homeostasis.
People who have a mutation in both copies of the MSTN gene have rather large muscle whether they train or not. Through my studies thus far, I would say that the majority of pro bodybuilders have a mutation in both copies of the MTSN gene, that's why they excel fast in the sport, or get over that hurdle that is so hard to leap to become a pro. And of course, their muscle receptors are more responsive to drugs than the average persons'.
With Myostatin eliminated, there will indeed be a rapid increase and an enhancement of hypertrophy, which is ideal for building muscle. Akt, which is a kinase that causes muscle hypertrophy in conjunction with protein synthesis will not be hindered, which is ideal to making new tissue. Also, cycles will not crash within 8 weeks, which means LBM gains will continue past week 8, but I don't know how long LBM gains would continue (I'm still researching).
There are a few things I found that "might" work to block myostatin but I'm not quite certain about them yet, so I won't disclose any info at the moment, but I will get in touch with you as soon as I'm sure about it..
For now, I would suggest for people who just cycle and don't blast and cruise to save their more anabolic roids for like weeks 7 or 8; especially tren becuase that will smash myostatin and extend the cycle for 3 or 4 more weeks.
