I reckon i've educated myself enough to not take the risk of stuffing around with my endocrine system at the time of my life when it is most vital with the risk it may not fully recover, risking closing my growth plates leaving me stuck with my current frame, the fact my test is already high at my age and will get higher...
Im progressing fine natural and if I wasn't i'd be going back to diet, routine etc.
It's an interesting topic to research for me too.
