HGH or mk677 is not USELESS for muscle growth HOWEVER when people make it out to be something that will gain large amounts of mass, that is absolutely false.. i cannot tell you how many people see a pro or competitor and say, "hes huge, he must be on hgh" and i fkng cringe... it can add a bit of lean muscle, yes, but if one is expecting to gain something like 10 lbs, they are extremely mistaken with a clear lack of understanding on it.. its a LONG TERM ped... people do not seem to grasp that.. there are studies back to the 90's on mk677 that anyone can go back and lookup about it... the size comes when its stacked with other compounds but it has a ton of benefits, especially long term.. the fat burning aspect especially is longer term but works extremely well.. there is just a clear and utter lack of the actual use and functioning of it.. it really goes in stages as its used on what one could expect over time etc.. ive covered this many times in posts and videos over the years
