This page compares what is documented about CJC-1295 (no DAC) and Sermorelin Acetate, rather than ranking them by effect. What each molecule is, the sizes and prices actually carried, what the certificate covers, and how the two differ on the bench. Everything here is research-use-only material and we do not publish outcome, dosing or administration content for any compound in the catalogue.
What is CJC-1295 (no DAC) and what is Sermorelin Acetate?
CJC-1295 (no DAC). CJC-1295 without DAC (mod GRF 1-29) carries four substitutions that resist enzymatic cleavage — the minimal stable GHRH fragment the literature keeps returning to.
Sermorelin Acetate. Sermorelin is GHRH(1-29) — the shortest fully-active fragment of the native hormone, and the baseline compound the whole GHRH-analogue literature builds from.

At their best sizes CJC-1295 (no DAC) works out at $6.80 per mg against $10.00 for Sermorelin Acetate — 47% more for the mg. Vial prices start at $34.00 and $50.00 respectively, which is the number most people compare and the one that says least, because the two are not sold in the same sizes. Full sizes, tier pricing and the lot certificate sit on the CJC-1295 (no DAC) page and the Sermorelin Acetate page.
What is each one studied for?
What the published literature investigates, which is a different question from what either will do, and the only one of the two a supplier can answer.
CJC-1295 (no DAC) is studied in ghrh analogue research. GHRH analogue research continues steadily, with the modified GRF(1-29) backbone the field's common denominator.
Sermorelin Acetate is studied in ghrh research. GHRH research still treats sermorelin as its baseline, with newer analogues defined by how they differ from it.
Studied in the same area does not make two compounds interchangeable, and the research library holds the per-compound documentation.
Sermorelin vs CJC 1295: how they differ on the bench
Sermorelin Acetate. Unmodified sermorelin is the most degradation-prone of the GHRH family we stock — the trade-off for being the native sequence. Storage discipline matters most here.
CJC-1295 (no DAC). The no-DAC and with-DAC forms are different molecules with different masses — the exact thing a proper LC-MS identity check settles on arrival.
On naming, because the two are written several ways and the difference is not always obvious: CJC-1295 (no DAC) is also written cjc 1295 or cjc-1295; Sermorelin Acetate is also written sermorelin. They refer to the same materials described here, and the certificate for a lot uses the name on this page. The comparison itself is usually typed CJC 1295 vs Sermorelin.
What actually differs between Sermorelin Acetate and CJC-1295 (no DAC)
The two are within a few percent of each other on molar mass — CJC-1295 (no DAC) at 3,367.9 g/mol and Sermorelin Acetate at 3,357.9 g/mol — so a milligram of one is close to the same number of molecules as a milligram of the other. That is unusual, and it is the only case where comparing the two by mass alone is nearly the same as comparing them by amount of substance.
Identity is the other analytical axis, and it is settled per lot rather than per compound. Sermorelin Acetate. This product is the acetate salt, so a lot certificate reports the salt rather than the free peptide figures above.
Both are released against a certificate reporting identity, purity by the stated method and net peptide content, readable before anything is bought.
Which is better, Sermorelin or CJC 1295?
Neither Sermorelin nor CJC 1295 is ranked against the other here, and the refusal is deliberate. Better, safer and stronger are questions about effects in a living system, and we sell neither compound for use in one — why none of these pages ranks two compounds sets out the reasoning in full.
What it does instead, for these two:
- CJC-1295 (no DAC) is the cheaper of the two per mg, at $6.80 against $10.00.
- Their molar masses are within a few percent, so a milligram of either is close to the same amount of substance.
- Both are carried in 2 sizes, and each lot carries its own certificate.
Every one of those is checkable before you buy.
Common questions
What is the difference between Sermorelin Acetate and CJC-1295 (no DAC)?
Different molecules before anything else: Sermorelin Acetate is C149H246N44O42S and CJC-1295 (no DAC) is C152H252N44O42. Sermorelin is GHRH(1-29) — the shortest fully-active fragment of the native hormone, and the baseline compound the whole GHRH-analogue literature builds from. CJC-1295 without DAC (mod GRF 1-29) carries four substitutions that resist enzymatic cleavage — the minimal stable GHRH fragment the literature keeps returning to.
Which one should I choose?
CJC-1295 (no DAC) is carried in 5 mg, 10 mg and Sermorelin Acetate in 5 mg, 10 mg, each lot with its own certificate. Which of those suits the work is yours to decide; everything here is research-use-only rather than guidance for use in a human or an animal.
Do both CJC-1295 (no DAC) and Sermorelin Acetate come with a certificate of analysis?
Neither is in stock at the moment, so in each case the certificate is the one attached to the lot that arrives. A certificate belongs to a lot, not to a product. It is linked from the product page, and reports identity, purity by the stated method, and net peptide content for the material actually in that lot.
Which is cheaper, Sermorelin Acetate or CJC-1295 (no DAC)?
Per mg, CJC-1295 (no DAC) at $6.80 against $10.00, taking each one's best size. By vial they start at $34.00 for CJC-1295 (no DAC) and $50.00 for Sermorelin Acetate, which is the comparison most people make and the one that says least, because the two are not sold in the same sizes.
Is a milligram of CJC-1295 (no DAC) the same as a milligram of Sermorelin Acetate?
By mass yes, and unusually so by amount of substance too: CJC-1295 (no DAC) is 3,367.9 g/mol and Sermorelin Acetate is 3,357.9 g/mol, within a few percent, so a milligram of either is close to the same number of molecules. That is rarely true of two different peptides and it is worth checking rather than assuming.
