I find that human growth hormone works better overall. It produces a bigger and more prolonged pulse of growth hormone, helps release fat stores more efficiently, and makes it simpler to trigger extra cell development. Also, shots are needed much less often. When growth hormone is injected under the skin from an outside source, the levels stay up for around six hours, mainly from how slowly the liquid absorbs through the fat tissue. In my own case, after using a mix of two peptides for some period, where one is notably more powerful than the other, my IGF-1 went up fifty percent from one hundred ten to one hundred sixty, and my z-score moved from negative point zero five to point five times the upper limit. Reports from others indicate some respond very strongly, reaching two or three times their normal amounts. Daily use of four international units of growth hormone gets my IGF-1 to about four hundred with one point seven five times the upper normal. Research into a different peptide with a longer duration showed it could boost growth hormone by two to ten times and IGF-1 by one and a half to three times over nine to eleven days in healthy people.
