The child you refer to is now in his 20s and still has the same body without working out. Being new to this forum and any forum I didn't realize my name would come up. Oh well you have it now. The myo blocker has just been released after trials and has no side effects, is therefore better than roids and a lot safer. The dosage is 1ml three times the first week 1ml twice the second week and one ml there after for about ten weeks is recommended, and it's not horrendously expensive. One of the great benefits I've found is there is a reduction in muscular inflammation and ache after workouts. One other thing, I am 56 now and it works fine on me, you don't have to be young.
You are correct, we use it in clinic for clients with chronic disease to prevent muscular atrophy. If you want more info that I can't give you without breaking forum rules look me up. Fair well for now from the lad from down under.
