I'm taking GHRH 400mcg, GHRP-6 100mcg and GHRP2500mcg. It is taken as an injection at night. The product is made from a compounding pharmacy. I started this about two months ago, initially gained about 6-8 pounds, then lost the weight. I am 64 inches and now about 158lbs. I am also very lean with good muscle density from years of weight training. I have maintained my calorie intake the same. I am noticing that the combination is leading to joint aches and I do not feel the same "pump" that I felt when I first started this regiment. Anyone with any thoughts???
