How Long Does a Sermorelin Vial Last?
Most sellers quote a monthly rate. 4 on our roster quote a vial or a kit instead, and a vial is not a month — how long it lasts depends entirely on a dose the seller does not publish. That makes those prices impossible to set beside a monthly one, which is why our cost tables leave them out rather than guess. You know the missing number. Put it in here.
Each is a seller that prices sermorelin by the vial rather than by the month, quoted from its own page — “Sermorelin 9mg”, read Sep 14, 2026. None of them publishes a dose, so the dose below is yours to set.
Opens at 300 mcg so the arithmetic has something to show. That is a placeholder, not a recommendation — use the dose you were prescribed.
Seven for nightly. Five is common too — several sellers dose weeknights only.
$181.71 a month
The vial holds 30 full doses and lasts 30 days — 4.3 weeks — at $5.97 an injection, or $2,180.54 across a year.
Ask about the beyond-use date. This works out to 30 days, and a reconstituted peptide has a shelf life the pharmacy sets — often shorter than that. If the vial expires before it empties, the real cost per month is higher than the figure above. How storage actually works.
Not modeled: dead volume left in the vial and syringe, and any overfill the pharmacy added. Both move the real number, and neither is published.
Why a vial price and a monthly price cannot be compared
A 15 mg vial at $80 sounds cheaper than $149 a month, and it might be twice the price. At 500 mcg nightly that vial is thirty doses and runs out in a month. At 200 mcg it is seventy-five doses and lasts most of a quarter. Same vial, same $80, and a threefold difference in what a month costs — decided by a number the seller leaves to a prescriber and never prints beside the price.
That is not a criticism of pricing by the vial. It is an honest way to sell a drug whose dose varies. It simply means the figure on the page is not comparable to the figure on the next page, and no amount of staring at the two will make it so.
The part the arithmetic cannot reach
Three things move the real answer and none of them is published. Dead volume — the liquid left in the vial neck and the syringe hub — means the last dose is often not drawable. Overfill runs the other way: pharmacies commonly put slightly more in the vial than the label says. And a reconstituted peptide has a beyond-use date, so a vial that lasts fifty days on paper may not be usable for fifty days.
The calculator flags the third whenever the arithmetic runs past twenty-eight days, because that is the point at which the question is worth asking the pharmacy. It is a prompt, not a finding about any particular product — what storage actually does to sermorelin goes through what is known.
Where the dose should come from
Yours, from whoever prescribed it. The field opens at 300 mcg so the example renders with real numbers in it, and that figure is a placeholder rather than a suggestion. It matters which one you use: the single adult trial dosed 10 micrograms per kilogram nightly, while sellers commonly market a flat 200 to 300 mcg, and for most adults those disagree by a factor of two or more. The dose-by-weight calculator puts your trial-equivalent dose next to the marketed range, and what the published dose actually was explains why the two differ.
Once you have a monthly figure, the annual comparison holds every seller that publishes one, and the reconstitution calculator turns your dose into the units to draw on the syringe. Prices change without notice; check the seller’s page before acting on any figure here, and tell us if one has moved.
