Body changes, not proven benefits
Studies in people measured how the substance changed the body. This did not establish a health benefit on its own.EmergingSome studies in people exist. 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.

Studies measured health results in people. The substance is still being studied and is not approved for that use. Important questions remain.EmergingSome studies in people exist. Important questions remain about benefit, safety, who it helps, or how long the effects last. This is not an approval or recommendation.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.

Approved products have evidence from studies in people that measured health results for specific uses. This does not show that every product, person, or use has the same result.EstablishedAn official agency review or strong, repeated studies in people support one clear use. That evidence applies only to the product, people, and use in the reviewed sources. 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.

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.

More about this topic
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, for a specific use. Studies of sermorelin, CJC-1295, and GHRP-6 measured hormone changes in people, not proven health benefits. Ipamorelin is still being studied; the reviewed records list no approved product.
This family is confusing because a peptide can raise a hormone level in people without showing that anyone builds muscle, loses fat, or recovers faster. Each page separates the hormone measurement from the claimed benefit and records current sport rules where available.
