Mod GRF 1-29 at a glance

CJC-1295 without DAC, also called modified GRF(1-29), is GHRH(1-29) with four amino acid changes that protect it from enzymes. Its half-life is longer than sermorelin’s, though still short.

It doesn’t have the drug affinity complex that lets CJC-1295 DAC bind albumin.

What studies report about Mod GRF 1-29

The amino acid changes were described in work on tetrasubstituted GRF analogs.

Most published human data are on the DAC version.

The full list of Mod GRF 1-29 papers is on PubMed, and most abstracts are free to read.

The biology behind Mod GRF 1-29

GHRH from the hypothalamus tells the pituitary to release growth hormone. Only its first 29 amino acids are needed for that.

Natural GHRH(1-29) lasts a few minutes before enzymes cut it. The four swaps in CJC-1295 without DAC block those cuts, so it lasts around half an hour. That keeps GH release pulse-like, which is why it’s often paired with a ghrelin-receptor peptide like ipamorelin.

Reconstituting Mod GRF 1-29 5mg

Divide 5mg by the volume of water and you have the concentration:

• 1mL of water: 5mg per mL
• 2mL of water: 2.5mg per mL
• 3mL of water: 1.67mg per mL

Bring the vial to room temperature, add sterile bacteriostatic water against the glass and swirl gently. It should go clear within a minute or two. Shaking only makes foam.

Dry vials last longest frozen at -20°C. Reconstituted solution goes in the fridge and is best used within four weeks or so.

Ordering enough Mod GRF 1-29 5mg

Work out the total amount the protocol needs first, then add about 20% for test runs and the odd lost dose. Ordering everything from one lot keeps the material consistent through the whole study.

Mod GRF 1-29 vs related compounds

In short, Mod GRF 1-29 is a stabilized GHRH(1-29) with a half-life of about 30 minutes, giving short, natural-looking pulses. Here’s how its neighbors differ:

• CJC-1295 DAC binds albumin and lasts about a week, giving a raised GH baseline instead of short pulses
• Sermorelin is the unmodified first 29 amino acids of GHRH, broken down within minutes
• Tesamorelin is full-length GHRH with a fatty acid cap, the only GHRH analog currently approved as a drug in the US
• Ipamorelin is the most selective ghrelin-receptor peptide, with little effect on cortisol or prolactin
• GHRP-2 is the strongest GH releaser of the original GHRPs, with a milder appetite effect than GHRP-6
• GHRP-6 releases GH and strongly raises appetite, the classic tool for feeding research
• Hexarelin is a very potent GHRP that also binds CD36 on heart cells

The GHRH analogs share one receptor and differ mostly in how long they last. Ipamorelin and the GHRPs work on the ghrelin receptor, so labs often pick one from each side. All of them are on our growth hormone peptides page.
