Biotech peptides CJC-1295: DAC, No DAC and the blends

Biotech peptides CJC-1295 comes two ways: with DAC for a long-lasting signal and without DAC for short pulses. Here is how they differ and which blend pairs with which.

What is biotech peptides CJC-1295?

Biotech peptides CJC-1295 is a GHRH analog. It’s built on the first 29 amino acids of growth hormone releasing hormone, the part that does the signaling, with four amino acid swaps that stop enzymes from cutting it apart in minutes. It tells the pituitary to release growth hormone.

There are two versions. CJC-1295 DAC 5mg carries a drug affinity complex that binds albumin in the blood. Mod GRF 1-29 5mg, also called CJC-1295 No DAC, doesn’t.

CJC-1295 DAC vs No DAC

In a 2006 study in the Journal of Clinical Endocrinology and Metabolism, Teichman and colleagues gave healthy adults a single dose of CJC-1295 with DAC. Growth hormone stayed raised for six days or more and IGF-1 for up to 11 days, and the half-life worked out to roughly six to eight days.

Mod GRF 1-29 lasts about 30 minutes, so it produces a pulse and then clears. Labs pick DAC for a raised baseline and No DAC to study the natural pulse pattern. The original paper is on PubMed.

Pairing CJC-1295 with a ghrelin agonist

A GHRH analog starts a GH pulse and a ghrelin receptor agonist makes it bigger, so CJC-1295 is usually paired with one. Ipamorelin is the most selective partner, and GHRP-2 the stronger one. Our GHRP-2 guide and tesamorelin guide cover the alternatives.

How much CJC-1295 DAC to order

Add up the total amount each group needs across every time point, then divide by the amount in one vial and round up. Add one spare vial for a repeat run or a lost dose. Buying everything at once keeps the whole study on one lot, which removes a variable you’d otherwise have to report. Keep unmixed vials frozen and reconstitute one at a time.

Designing a study around CJC-1295 DAC

Growth hormone studies have to deal with the pulse problem: GH rises and falls through the day, so sampling times matter as much as the dose. Labs usually take frequent blood samples after each dose and measure IGF-1 as a slower, steadier marker. Comparing DAC with No DAC in the same design shows clearly how the long half-life changes the pattern.

Storing biotech peptides CJC-1295

Freeze the sealed vial at -20°C when it arrives. Reconstitute it with sterile bacteriostatic water, keep the solution at 2 to 8°C and use it within about four weeks. The product page for CJC-1295 DAC 5mg lists the concentration you get with 1mL, 2mL or 3mL of water.
