WHY THE FUCK NOT? IM NOT LOOKING TO BE A LITTLE PUSSY OUT HERE. I WANNA LOOK ROUND & FULL.
ALL WOMAN WANNA BE WITH ME, ALL GUYS WANNA BE LIKE ME. GH IS THE LEAST HARMFUL OF THESE PEDS, ITS JUST EXPENSIVE...VERY.
because you natural gh levels are adequate right now, if your only using 4iu, that isn't going to help you that much at 20 yrs of age. I would wait till your 23 - 25 to start it, and use it at 5 - 15 iu as you can handle. Whatever works for you, but 4iu isn't going to get you a pro card.
Also please don't use insulin. I don't think anyone wants to remember the current generation of bodybuilders we have now that are built on slin and gh.
