Two Snakeoil salesmen. Milos and Dave.
No single hormone chemical drug allows you to gain 40lbs of quality muscle in one month and especially not Insulin.
Insulin does not build any muscles just like synthol doesnt build any muscles...all fake illusion two worst things to take followed by thyroid.
HGH, test, igf-1, tren, orals, injectables nothing puts 40lbs quality muscle in a month...Nothing!
oh yeah Essential aminos best single supplement....Wrong!
