mod grf 1-29
GH AXIS · GHRH-R AGONIST · 29 AA · T½ ~30 MIN
also: CJC-1295 without DAC · CJC-1295 no-DAC · tetrasubstituted GRF(1-29)
Mod GRF 1-29 is the tetrasubstituted GHRH(1-29) analogue that forms the peptide backbone of CJC-1295, without the drug affinity complex that binds albumin. The four substitutions extend its half-life to at least about 30 minutes compared with under 10 minutes for unmodified GRF(1-29), but FDA's 2024 review identified no pharmacokinetic data and no clinical studies for the non-DAC form specifically.
// our evidence grade — unedited
It is the same peptide backbone as CJC-1295 with DAC minus the albumin linker, but stripped of that linker it has essentially no published human trial data of its own, and FDA stated it identified no pharmacokinetic data for the non-DAC form at all.
We grade this compound and we sell it. The grade is set against our published criteria before any stocking decision and is not adjusted because it is in the catalogue.

| full name | [D-Ala2, Gln8, Ala15, Leu27]-human growth hormone-releasing factor (1-29) amide |
| cas | 446036-97-1 |
| formula | C152H252N44O42 |
| molar mass | 3367.95 g/mol |
| purity | ≥ 99% HPLC |
| form | lyophilised powder, sealed vial |
| storage | Lyophilised peptide is stored desiccated at -20°C or below, protected from light and moisture, for long-term laboratory storage; material in active use is held at 2-8°C. Reconstituted solution is kept at 2-8°C and used within a short window rather than refrozen. |
| solubility | Reconstituted with bacteriostatic or sterile water in laboratory settings; as a hydrophilic 29-residue peptide with no maleimide group it dissolves readily in aqueous buffer without organic co-solvent. |
| sequence | Tyr-D-Ala-Asp-Ala-Ile-Phe-Thr-Gln-Ser-Tyr-Arg-Lys-Val-Leu-Ala-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Leu-Ser-Arg-NH2 |
