How many units of CJC-1295 (DAC) should I draw?

It depends on your vial size, BAC water, and dose. For a 2mg vial with 2mL BAC water, a beginner dose of 1000mcg is typically 100 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to CJC-1295 (DAC)?

The standard amount is 2mL of bacteriostatic water for a 2mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a CJC-1295 (DAC) vial last?

At a beginner dose of 1000mcg weekly, a 2mg vial lasts about 2 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for CJC-1295 (DAC)?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

After 1 half-life (8d): 50% remainsAfter 2 half-lives (16d): 25% remainsAfter 3 half-lives (24d): 12.5% remains

At a 2mg dose: 50% = 1.0mg remaining after 8d. Recommended frequency: Weekly.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

About CJC-1295 (DAC)

CJC-1295 with DAC (Drug Affinity Complex) is a long-acting growth hormone releasing hormone (GHRH) analog. The DAC modification allows it to bind to albumin in the blood, extending its half-life to about 8 days. This creates sustained, elevated growth hormone levels rather than natural pulsatile release. Best for those wanting steady GH elevation with minimal injection frequency.
