Short answer
HGH (somatropin) is growth hormone itself, FDA-approved for diagnosed deficiency and a few other conditions; it raises levels directly and can suppress your own production. Sermorelin is a GHRH analogue that asks your pituitary to release its own hormone in natural pulses, so its effect is smaller and depends on a working pituitary. Using either for anti-aging or bodybuilding is off-label, and HGH distribution for those uses is restricted in the US. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.

Community Q&A
- Is sermorelin as effective as HGH?
- No. It produces a smaller, pulse-based rise and needs a working pituitary; HGH replaces the hormone directly.
- Why do people choose sermorelin over HGH?
- It keeps the body's own feedback loop and is easier to get prescribed than HGH, which is tightly restricted for off-label use.
- Does Peptide Confessions give dosing?
- Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.
- Sermorelin vs HGH — what is the difference?
- HGH (somatropin) is recombinant growth hormone. Sermorelin is a GHRH analogue that signals GH release rather than replacing GH.
- Where are sermorelin reports?
- See the Sermorelin peptide hub and Sermorelin in Canada.
- Does this page give dosing, prices or sourcing?
- No. We never publish dosing, prices or sourcing, and nothing here is medical advice.
