It's possible! This could have more to do with your diet than with the GH though. Sounds like your metabolism is racing. I've had times that I turn a fan directly on me while eating because I just pour sweet. Whatever the case, I bet that feeling hot and sweating is a good sign. If you really want to ramp your program up, you should really add some anabolics. GH alone will not produce great muscel gains, but when combined with steroids, growth gets much better
