Why buy Sermorelin Peptide from TrueBond Labs
A certificate for each size
The 5mg and 10mg vials come from separate lots, and an independent third-party lab tested each one. Both certificates confirm identity and report HPLC purity of at least 99%. Start with the current sermorelin certificate, or find either size on our lab reports page by lot code.
5mg or 10mg
Same peptide, two fills. Both sizes are freeze-dried powder in a sealed 3 mL vial with the lot code on the label. Because they're separate lots, look up the code on the size you have.
The parent sequence
Sermorelin is the unmodified GRF (1-29) sequence that CJC-1295 No DAC was built from. Tesamorelin is the longer 44-residue analogue. All three sit together on our research peptides page.
What is Sermorelin Peptide?
Sermorelin is a synthetic 29-amino-acid peptide, also known as GRF (1-29) or GHRH (1-29) amide. Its sequence matches the first 29 residues of growth-hormone-releasing hormone, with an amidated C-terminus. It's the parent sequence that later analogues were built from.
Sermorelin appears in published laboratory research on growth-hormone-axis signaling. Because its sequence is unmodified, it's a common point of comparison for modified analogues, and none of those analogues is interchangeable with it. It's also often listed next to ipamorelin, a much shorter peptide from a different class, and our ipamorelin vs sermorelin comparison covers how the two differ. Check which sequence your work calls for before you order.

Sermorelin Peptide: frequently asked questions
Is sermorelin the same as GRF 1-29?
Yes. Sermorelin is the common name for GRF (1-29) amide. Depending on the catalog, you'll see it written as GRF 1-29 or GHRH (1-29). Mod GRF 1-29 is a different peptide, though. That one is CJC-1295 No DAC, which has four substituted amino acids.
What is the difference between sermorelin and tesamorelin?
Sermorelin is the first 29 residues of GHRH, with nothing added. Tesamorelin uses the full 44-residue GHRH sequence and carries a trans-3-hexenoyl group at the N-terminus. So one is shorter and unmodified, the other longer and modified. Our sermorelin vs tesamorelin page puts the two side by side.
Sermorelin vs CJC-1295: which is which?
Both are 29 residues long. Sermorelin is the native GRF (1-29) sequence. CJC-1295 No DAC swaps the amino acids at positions 2, 8, 15 and 27. CJC-1295 with DAC adds a linker group on top of that. We carry sermorelin and CJC-1295 No DAC, but not the DAC version.
Is your sermorelin third-party tested?
Yes, both sizes. An independent US lab tested our published 5mg and 10mg lots and confirmed identity for each. The certificates are filed on our lab reports page by lot code, and each one is posted as a full PDF.
How should I store sermorelin?
Put the sealed vial in a −20°C (−4°F) freezer and keep it away from light. Stored that way, the freeze-dried powder holds for 24+ months in either size. Avoid repeated freeze/thaw.
