Peptides do work, but more subtly than steroids or even HGH...meaning you can't run them for 2 months and think you are going to notice lot of difference...over a period of 6 months to a year, yes you will notice some difference, but IMO they should be used once you get to a certain point, not to get to that point.
Plus its become harder to find quality providers since a few professional chemical companies shuttered their peptides division, such as Pepbridge. Sometimes you get real stuff, sometimes you get bunk...
IMO, if you are looking for a GH kick, I would go with a SARM called MK-677. ITs been shown in clinical trials to greatly increase growth hormone release, in the same manner as a lot of peptides do, and its easier to find a quality provider of this. Much less expensive in the long run as well...
