These two sit in the same mechanism class, which is exactly why they get swapped for each other in a checkout. Same class is not the same drug. They differ on how long each one lasts and on regulatory history — and CJC-1295 isn’t one thing to begin with. With the drug-affinity complex attached, its recorded half-life goes from minutes to days — a different dosing product under the same name.

Citation status, counted from the records behind this page rather than typed: 12 of 12 pharmacological figures on it are recorded in this site’s data but not yet traced to a published source, and they are marked [needs citation] where they appear. Where the writing below restates one of those figures, it rests on the same unsourced record. The open sourcing work is listed in the repository’s content to-do. This line counts itself down as sources land.
Side by side
CJC-1295 here means the form without DAC, which is the one usually sold in a nightly stack. The DAC form is compared separately below, because treating them as one column would average away the one number that separates them.
Every pharmacological figure below carries its citation status. A cell marked [needs citation] is recorded in this repository but not yet traced to a source, and it is printed that way rather than dressed up.

On cost: 0 of 3 seller records on this site are real — the rest are placeholders carrying fictional figures — so there is no monthly price here that anyone has read off a seller’s own page. The cost row says so rather than quoting a number we made up. This sentence is computed from the records and will change on its own when real ones land.
CJC-1295 is two products
A seller listing “CJC-1295” may mean either form, and the two are recorded here with the same mechanism and very different half-lives. If you are being quoted a price, which form it buys is the first thing to establish — it decides whether you are injecting nightly or weekly, and the two schedules are not the same purchase.

Whether these belong in one column or two is an open question in this site’s brand book. They are two here, because one column would have to carry a single figure, and no figure describes both a form recorded in minutes and a form recorded in days.
The spread, on one scale
All three records on one logarithmic axis — the same scale the full matrix uses, so the distances are comparable across the site. This is the clearest argument on the page that “GHRH analog” is a class and not a specification.

Plasma half-life, logarithmic scale. The spacing is the point: linear spacing would put four of these five inside one smudge at the left edge. Where a figure is a range, the bar is the range.
Sermorelin is recorded as 10–20 min, CJC-1295 (no DAC) as ~30 min, and CJC-1295 + DAC as ~6–8 days. Where a figure is a span it stays a span, on the bar and in the label. Averaging a span to a single number would make the chart tidier and the figure wrong.
Same class is not the same molecule
Sharing a mechanism row tells you these molecules act on the same system. It does not tell you they act the same way, for the same length of time, at the same dose, or with the same evidence behind them. The rows where they differ are the ones worth reading, and on this page that is the half-life row and the regulatory row.
It also does not follow that the longer-lasting form is the better one. A longer half-life means fewer injections; it also means that once a dose is in, there is longer to wait for it to clear. Those are trade-offs to weigh with a clinician, not a ranking.
Regulatory status
Sermorelin is recorded here as withdrawn; CJC-1295 as not approved in both forms. State them and stop: an unapproved molecule is not thereby a bad one, and an approved one is not thereby better. What the statuses do settle is that none of the three reaches a US buyer as an approved, off-the-shelf product, so anything quoted to you is compounded. Who compounds it and under what oversight is a question for the seller and for a clinician. Nothing here is medical advice.
Sources
Figures marked [needs citation] come from this project’s reference notes and have not yet been matched to a published document. They are printed with the marker rather than withheld, so you can see which parts of the comparison are traced and which are still owed. Corrections are published, dated and signed on the corrections page; the method is on the editorial policy page.
Where each one is sold
3 sellers in this site’s records sell CJC-1295 (no DAC) or CJC-1295 + DAC or Sermorelin. 2 of them pay us a commission; 1 does not. Both kinds appear here in the same format, and the line under each button says which it is. The full accounting is on the disclosure page.
3 of the 3 records below are a placeholder with a fictional price, kept here only to exercise the outbound mechanics. Nothing in those rows describes a real company. This notice is computed from the records, so it clears itself when they are replaced.

Placeholder record. Prints a standing month-to-month rate before the intake and names its compounding pharmacy on the peptide page rather than only on the GLP-1 one.
$205 per month — CJC-1295 + ipamorelin, 300 mcg nightly · read 2026-09-02
Placeholder record. Sells the stack rather than either molecule alone, so the figure is for the combination and is not comparable to a single-agent price.
