As far as how much to run really varies on the quality. Pharm HGH is typically more potent and pure than most UGL or generics. If you find the right source for UGL or generic that’s not ghrp or laced with another non gh product, your in the money and saving a ton of money! Ask me how I know. 2iu’s can be very beneficial pending what you are trying to accomplish. Like anything else if you overdo it, sides can take over and be dangerous over time. GH is a slow race and doesn’t work miracles over night. The best about gh is that it’s enhances the gear you are currently running, very good stuff for sure! Total body goodness from well being to aiding in fat loss, muscle building and repair etc...
