GHRP by itself will not compare to real hgh. Combining GHRP with something like cjc, or imaporelin, then you will have a synergistic effect which will increase the effectiveness exponentially. You see, one of them will cause your body to produce more growth hormone during a pulse. The other will increase the amount of pulses you have throughout the day. I've seen blood work on these peptides showing hgh levels above the normal range, but it was in the low teens whereas typical hgh levels you'd like to see above 20.
