CJC-1295
Two milligrams is not much powder.
CJC-1295 is usually sold in 2 mg vials, which is a small mass to divide into microgram doses. The water volume you choose is what makes those doses measurable.

The science
Why a small vial is easier to dose accurately
01
CJC-1295 is a growth hormone releasing hormone analogue supplied as freeze dried powder, most often 2 mg per vial and sometimes 5 mg. Doses are usually discussed in the 100 to 300 microgram range.
02
A small vial is an advantage here, counterintuitively. Two milligrams reconstituted with 2 ml gives 1 mg per ml, a round number, and at that concentration a 100 mcg dose is exactly 10 units. Clean arithmetic reduces the chance of a mistake, and 10 units is easy to see on a barrel.
03
The same dose from a 5 mg vial in 1 ml means 5 mg per ml, so 100 mcg is 2 units. That is arithmetically fine and practically poor, because two units sits at the bottom of the barrel where the graduations are widest relative to what you are measuring.
04
A useful habit is to pick the water volume that makes the concentration a round figure. One milligram per millilitre means micrograms and units line up in a way you can check mentally: 100 mcg is 10 units, 150 mcg is 15 units. Being able to sanity check a calculator without a calculator is worth designing for.
Lookup
2 mg and 5 mg vials at each water volume
A 2 mg vial in 2 ml is 1 mg per ml, which is dilute enough that microgram doses sit in a comfortable part of the barrel. The table shows what every other combination gives you.

A dot marks a combination that falls under two units or overflows a 100-unit barrel. Both are hard to measure accurately, so they are worth avoiding rather than eyeballing.
Regulatory status
CJC-1295 has never been approved
CJC-1295 is an investigational growth hormone releasing hormone analogue. Development did not result in approval, so there is no prescribing information for it and no regulator has published a dose.
It is prohibited at all times in tested sport under the World Anti-Doping Agency rules covering peptide hormones and releasing factors.
Everything in the table above is arithmetic performed on conventions, not on guidance. The distinction is worth holding onto: this page can tell you that 100 mcg from a 1 mg per ml solution is 10 units, which is a fact about division. It cannot tell you that 100 mcg is an appropriate amount, and neither can any other page that does not have a label behind it.
FAQ
Common questions
How many units is 100 mcg of CJC-1295?
From a 2 mg vial reconstituted with 2 ml, the concentration is 1 mg per ml, so 100 mcg is 0.1 ml, which is 10 units on a U-100 syringe. Change the water volume and the answer changes: the same vial in 1 ml puts 100 mcg at 5 units. Always record the water volume alongside the units figure.
How much bacteriostatic water for a 2 mg CJC-1295 vial?
2 ml is a common choice because it gives a concentration of exactly 1 mg per ml, which makes the microgram to unit conversion straightforward to check by eye. Anything from 1 to 3 ml keeps typical doses in a readable range. The calculator shows where each option puts your dose.
What is the difference between CJC-1295 with and without DAC?
DAC is a drug affinity complex that extends how long the compound stays active, and the two versions are therefore discussed with different frequencies. That difference does not change the reconstitution arithmetic at all: a milligram of powder in a millilitre of water is the same concentration either way. It changes how often a dose is taken, which is a clinical question rather than a mathematical one.
Can I use regular sterile water instead of bacteriostatic water?
Bacteriostatic water contains benzyl alcohol as a preservative, which is what allows a vial to be entered more than once over a period of days. Plain sterile water has no preservative, so a multiple use vial reconstituted with it carries a much higher contamination risk. For anything you intend to draw from more than once, bacteriostatic water is the reason the option exists.
Is CJC-1295 approved for human use?
No. CJC-1295 has not been approved by the FDA or any comparable regulator, so no official dosing information exists for it. It is prohibited in tested sport. The calculator converts figures you provide and makes no claim that a safe or effective human dose has been established.
