It's frowned upon by the mainstream medical community which this area/forum supports. Rightfully so in most cases since GH is abused but, you hear guys talk about "blasting" on here too so that's in the same category IMO.
In any case, GH q's are best for the GH forum fyi. You can get good advice and hear the results of others.
Since you are TRT too we are in the same boat.
