Growth hormone-related peptide therapies are frequently marketed for body composition, recovery, sleep, anti-aging and performance. These claims can blur important differences between FDA-approved drugs, historically approved products, investigational peptides and compounded preparations. This guide explains the categories in plain language.
GHRH analogs mimic signaling from growth hormone-releasing hormone, while growth hormone secretagogues stimulate growth hormone release through other receptor pathways. Tesamorelin and sermorelin are examples of GHRH-related agents; ipamorelin is commonly described as a growth hormone secretagogue. CJC-1295 is a synthetic GHRH analog that has been evaluated in limited human research but does not have an FDA-approved therapeutic indication.
Not every substance promoted as a peptide therapy has the same evidence, manufacturing standards, labeling or safety information. Tesamorelin has an FDA-approved product for a specific HIV-associated lipodystrophy indication. Other peptides frequently marketed for wellness or body composition may be investigational, unapproved, or available only through pathways that require careful regulatory and clinical consideration.
A physician should evaluate symptoms, diagnoses, medications, metabolic risk, endocrine history, sleep, nutrition, body composition goals, contraindications and relevant laboratory testing when clinically appropriate. The goal is not to select a peptide first and justify it later; it is to determine whether any treatment is medically appropriate and whether an evidence-based alternative is preferable.

No. They act through signaling pathways that may influence endogenous growth hormone release rather than simply being recombinant human growth hormone.
Broad anti-aging claims are not established for many of the peptides marketed in this category. Evidence and approved indications vary substantially by molecule.
