I heard a guy on the radio this morning who had run a gym since 1980 and had been involved quite heavily in sport sciences. He said that without the HGH or steroids, Peptides are useless. Used alone, they are like putting a turbo on a car with no engine. However used with HGH or Steroids, they do have a true turbo effect. He went on to say that sports scientists are more like salesman than doctors and as HGH and steroids are detectable, they cannot use them, so to justify their existence, they push the peptides in the hope that they will have some sort of placebo effect at best.
