Topic summary
Separate a measured hormone change from claims about muscle, fat loss, recovery, and longer life.
What these peptides have in common
Peptides sold as growth hormone alternatives act before the body releases growth hormone. They do not replace growth hormone. Of the five reviewed here, only tesamorelin has an FDA-approved product. Its approval covers one narrow use. Sermorelin, CJC-1295, and GHRP-6 have human hormone-response data, not proven health outcomes. Ipamorelin remains investigational, and the reviewed records list no approved product.
That pattern is the reason this family is confusing. A peptide can reliably raise a hormone level in people and still have no evidence that anyone builds muscle, loses fat, or recovers faster because of it. Each brief separates the hormone measurement from the promoted benefit, and records the current anti-doping position where one exists.

Important questions remain about benefit, safety, who it helps, or how long the effects last. This is not an approval or recommendation.
CJC-1295
Short studies in healthy adults found that CJC-1295 raised growth hormone (GH) and insulin-like growth factor 1 (IGF-1). These hormone measurements do not prove better recovery, muscle gain, or fat loss.

Ipamorelin
A short human study measured growth-hormone release, but it did not prove health benefits. A different phase 2 study did not show benefit on its main or other measured outcomes.

That evidence applies only to the product, people, and use we reviewed. It does not mean the product is safe or effective for everyone.
Tesamorelin
An approved medicine for one specific HIV-related body-composition outcome. It is not a general weight-loss or anti-aging medicine.

Sermorelin
Studies in people show a growth-hormone response. They do not prove broad anti-aging or muscle-building benefits. Former Geref products are no longer sold.

GHRP-6
A six-amino-acid research peptide. Small human studies show short-term growth-hormone changes, not proven muscle, fat-loss, or other lasting health benefits.
