What a CJC-1295 with DAC dose actually costs

Cost per milligram is the wrong unit

Sellers price CJC-1295 with DAC by the vial, and vials are labeled by total peptide weight. That invites a simple division: price divided by milligrams. The result is a number that looks like cost per dose but is not, because you cannot always spend every milligram.

A vial only produces whole doses. Whatever is left over after the last full dose sits in the vial as a remainder. It was paid for. Unless you have a use for a partial amount, it is a cost with no dose attached to it.

So the honest calculation has two steps. First, count how many whole doses the vial yields. Second, divide the vial price by that count. The gap between the two methods is the stranded product, and the table on this page quantifies it for the two vial sizes commonly sold.

What the table shows

Two things stand out. The 2 mg vial at a 2 mg dose is the clean case: 1 whole dose, 0 mg stranded, 0 percent wasted. Every milligram bought becomes a milligram used, so cost per dose and vial price are the same figure.

The 5 mg vial is the case where the arithmetic bites. At the same 2 mg dose it produces 2 whole doses and leaves 1 mg behind, which is 20 percent of what you paid for. If the 5 mg vial is not priced at least far enough below two of the 2 mg vials to absorb that 20 percent, the larger vial is the more expensive option per dose despite looking like the bulk buy.

That is the general lesson: a larger vial is only cheaper per dose if its discount exceeds its waste rate. The waste rate is fixed by the arithmetic between vial size and dose size. It does not depend on price, so you can work it out before you look at any listing.

Water volume changes nothing about cost

Listings for CJC-1295 with DAC show reconstitution with 1, 2 or 3 mL of water. Which one you use determines concentration, and concentration determines how many syringe units a given dose occupies. It does not change how many milligrams are in the vial.

Because cost is driven by milligrams and doses, not by volume, the stranded fraction in the table is the same at every water volume. A 5 mg vial at a 2 mg dose strands 1 mg whether it was mixed in 1 mL or 3 mL.

Water volume matters for measurement, not for economics. Very small volumes are harder to measure accurately on a syringe, and inaccurate measurement is its own way to lose product, but that is a separate problem from the divisibility problem this page covers.

What this page cannot tell you

We hold no reliable human pharmacokinetic data for CJC-1295 with DAC. This site therefore makes no claim about its half life, how long it takes to clear, or whether it accumulates with repeated use. Anything you read here concerns concentration, volume and division only.

That limitation matters for cost specifically. Cost per dose is only meaningful if you know how often doses are taken, and dosing frequency depends on pharmacokinetics we do not have. We can tell you what one dose costs given a vial and a dose size. We cannot tell you what a week or a month costs, because we cannot tell you how many doses a week or a month contains.

We also do not say what dose to use, what to expect from it, what adverse effects occur, or whether the compound is safe or effective. There is no medical review behind this page. CJC-1295 with DAC is not approved by any regulator for human use. Those are questions for a clinician, and this is a calculator.

Running the numbers on a listing

Take the vial size and the dose size you intend to price. Find that row in the table and read off the whole dose count. Divide the listed vial price by that count. That figure is comparable across sellers and across vial sizes in a way that cost per milligram is not.

Then check the stranded column before comparing to a different vial size. A row with a nonzero remainder is telling you that part of the purchase has no dose attached, and the seller's price per milligram will look better than the price you actually pay per dose.

One caution on the whole dose count itself. It assumes you recover the full labeled contents, which in practice you will not, because residue clings to the vial and the syringe. The counts here are upper bounds. Real cost per dose is at or above what the arithmetic gives you, never below.

What we do not know

We hold no reliable human pharmacokinetic data for CJC-1295 with DAC, so this site makes no claims about its half life, how long it takes to clear, or how it accumulates. The arithmetic below concerns concentration and volume only.

This page answers arithmetic and handling questions. It does not tell you what dose to take, what to expect, or whether anything is appropriate for you, and there is no medical review behind it.

Common questions

Is a 5 mg vial of CJC-1295 with DAC cheaper than a 2 mg vial?

It depends entirely on the prices in front of you. At a 2 mg dose the 5 mg vial yields 2 whole doses and strands 1 mg, a 20 percent loss, while the 2 mg vial yields 1 whole dose with nothing stranded. The larger vial only wins if its price advantage is bigger than that 20 percent.

What does stranded mean here?

Stranded is the peptide left in the vial after the last whole dose has been drawn. It is product you paid for that does not become a dose. In the 5 mg vial at a 2 mg dose, that remainder is 1 mg.

Can I use the stranded milligram?

That is a dosing question and this site does not answer dosing questions. The arithmetic simply records that a remainder exists and how large it is. Whether a partial amount has any use is between you and a clinician.

Does mixing with 1 mL instead of 3 mL make the vial go further?

No. Water volume sets concentration, which sets how many syringe units a dose occupies. The number of milligrams in the vial is unchanged, so the number of whole doses and the stranded amount are identical at 1, 2 or 3 mL.

How much does a month of CJC-1295 with DAC cost?

We cannot compute that. A monthly figure requires a dosing frequency, and frequency depends on pharmacokinetic data we do not have for this compound. We make no claim about its half life, clearance or accumulation, so we stop at cost per dose.

Why is the real cost slightly higher than the calculated cost?

The whole dose counts assume you extract the full labeled contents. In practice some peptide remains as residue in the vial and the syringe. Treat the table as an upper bound on doses per vial and therefore a lower bound on cost per dose.
