Bros, GHRP-2 and GHRP-6 are very similar but with the two versions you'll end up having more appetite so it really depends on what you're looking for. Either way you want to run them at 125 to 250 mcg once to twice a day.
Bros, you got one of the best legs I've ever seen in my life. Calves and your hamstrings are looking really peeled. You got some BBC genetics I can tell. @Coach R. AP
