Short answer
Both push the pituitary to release growth hormone, through different receptors. Sermorelin mimics GHRH, the hypothalamic "release" signal, and was once FDA-approved for children. Ipamorelin mimics ghrelin at the GH-secretagogue receptor; it reached human trials for post-surgical gut recovery but was never approved. People often pair a GHRH analogue with a ghrelin mimetic because the two signals work together. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.

| Common user claims | Sleep, recovery | Sleep, "HGH without HGH" |
What users report
No confession compares the two head to head yet. Sermorelin appears in one report (#119, sleep); ipamorelin mostly appears with CJC-1295 — see the CJC-1295 + ipamorelin page.

Community Q&A
- What is the difference between ipamorelin and sermorelin?
- Ipamorelin acts on the ghrelin (GH-secretagogue) receptor; sermorelin acts on the GHRH receptor. Both raise your own growth hormone.
- Is either approved?
- Sermorelin was FDA-approved for paediatric GH deficiency until the maker withdrew it in 2008; ipamorelin was never approved.
- Are there head-to-head user reports?
- Not yet. Reports here mention each separately.
- Does Peptide Confessions give dosing?
- Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.
- Ipamorelin vs sermorelin — what is the difference?
- Ipamorelin is a GHRP-class secretagogue; sermorelin is a GHRH analogue. Different molecules often discussed for overlapping goals.
- Where should I read reports?
- See the Ipamorelin and Sermorelin peptide hubs.
- Does this page give dosing, prices or sourcing?
- No. We never publish dosing, prices or sourcing, and nothing here is medical advice.
