CJC-1295 DAC vs no DAC: research comparison
Catalog and forum language often collapses “CJC-1295” into one name, but with-DAC and without-DAC (Modified GRF 1–29) are different molecular constructions. This comparison follows the identity framing used in our blog posts — not a medical recommendation — and points to PubChem/CAS resources for registry checks.
Neither CJC-1295 with DAC nor Modified GRF (1–29) is currently a standalone SKU in the BioLabs Research live catalog. Treat this page as an identity primer and follow the linked blog articles for formula-difference detail.
Quick comparison
| Field | First | Second |
|---|---|---|
| Common name | CJC-1295 with DAC | CJC-1295 no DAC / Mod GRF 1–29 |
| Key structural idea | GHRH analogue + Drug Affinity Complex (albumin-binding motif) | Modified GRF (1–29) without DAC |
| Illustrative CAS | 863288-34-0 (with DAC listings) | Verify Mod GRF listing on PubChem/lot COA |
| Catalog SKU on this site | Not listed as standalone | Not listed as standalone |
CJC-1295 with DAC
CJC-1295 with DAC refers to a tetrasubstituted GHRH analogue conjugated to a Drug Affinity Complex intended to extend circulating half-life via albumin binding in published research descriptions. Public registry entries commonly cite CAS 863288-34-0 for CJC-1295-type constructs; always confirm the exact structure against the supplier COA because naming collisions are common.
Identity reading: CJC-1295 DAC vs Modified GRF identity and DAC vs no-DAC formula difference.
CJC-1295 without DAC (Modified GRF 1–29)
“CJC-1295 without DAC” in vendor language usually means Modified GRF (1–29) — a shorter GHRH analogue lacking the Drug Affinity Complex. Half-life and assay design expectations differ from the DAC conjugate even when marketing names overlap. Sequence and modification list on the COA are the source of truth.
Because BioLabs Research does not currently list a standalone CJC SKU, use PubChem and the blog identity posts above when drafting protocols. Related secretagogue blend context on-site: Tesamorelin / Ipamorelin blend identity.
Key differences
- DAC adds an albumin-binding complex; no-DAC Mod GRF does not.
- Marketing name “CJC-1295” is ambiguous — insist on sequence + CAS on paperwork.
- Pharmacokinetic research framing differs; assay timing should match the construct.
- No standalone CJC SKU on this catalog at publish time — identity-only comparison.
Which for which research context
With DAC when literature or the assay plan explicitly requires the Drug Affinity Complex conjugate and cites a matching CAS/structure.
No DAC / Mod GRF when the protocol specifies Modified GRF (1–29) without albumin-binding conjugation.
If you need an on-catalog GHRH/GHRP-adjacent blend for other work, review Tesamorelin / Ipamorelin as a separate identity pair — not a CJC substitute.

All discussion on this page is limited to chemical identity, public registry identifiers, and laboratory research framing. BioLabs Research lists reagents for in-vitro and analytical work only. Catalog availability, vial strength options, and lot documentation (when a COA PDF is hosted) should be confirmed on the product page and in the COA Library before purchasing for a protocol.
When comparing sequences or CAS numbers across vendors, verify the exact salt form, fragment length, and any N-terminal modifications against the lot COA. Public CAS entries describe a named chemical entity; they are not a substitute for lot-specific HPLC or MS results. For dilution math after a vial is in hand, use the solution dilution calculator. For mass-unit conversions, use the unit converter.

Document control tip: store the supplier’s sequence PDF beside your method SOP so future readers can see whether DAC was present. Do not rely on cart titles alone when re-ordering months later.
