First off, your post is barely legible and filled with factual errors (igf-1 and ghrp-6 are two entirely different substances). From that unintelligble mess, I'm guessing that you are asking which is more effective short term growth hormone releasing peptides usage or long term GH secregoues from the supplement industry. The answer is neither; peptides like grhp-6 are best used over a period of six months or more.
However, judging by your post, IMHO, you should just stick with nutritional supplements atm. Please do A LOT more research before you consider putting anything into your body.
