Sermorelin dosage: what sellers actually print

Five out of ninety sermorelin sellers print a dose anywhere a reader can see it. The other eighty-five will sell you a monthly subscription without telling you how much drug is in it.
That is the useful thing to know before you shop. A price you can compare and a dose you cannot is half a price, and the five that do publish a number don’t agree with each other — the range runs from 200 mcg a night to 450 mcg a night, on schedules that vary from five nights a week to seven.
The five that print a number
Quoted from each seller’s own sermorelin page, in its own words. Where a seller prints a vial strength instead of a dose, that’s noted — a concentration is not a dose.
Scroll the table sideways for the remaining columns.
| Seller | What the page prints | Schedule as printed |
|---|---|---|
| Arc-1 | 300 mcg or 450 mcg | “Nightly Monday-Friday” |
| Liberty | 200 mcg, then 300 mcg, then 300–500 mcg | At bedtime. Weeks 1–2, weeks 3–6, then months 2–3 |
| Neo Soma Healthcare | 300 mcg | “300mcg/day, 5 days a week” |
| Lasara | 2,000 mcg/mL vial strength; 0.2 mL injected, which works out to 400 mcg a dose | “Inject 0.2mL subcutaneously each weekday” |
| BloomMD | 1,000 mcg/mL vial strength. No dose printed | Not printed |
A vial strength is not a dose
Two of the five print how concentrated the vial is and leave the arithmetic to you. Lasara publishes both halves — a 2,000 mcg/mL vial and a 0.2 mL injection — so the dose is recoverable at 400 mcg. BloomMD publishes a 1,000 mcg/mL strength and a 3 mL total volume and never says how much of it you inject, which means the page tells you what you are buying and not what you are taking.
Watch for this when you compare two subscriptions. A cheaper plan at a lower dose is not a cheaper plan.
The stepped ladder, where it appears
Liberty is the only one of the ninety that publishes a titration schedule with the weeks attached: 200 mcg at bedtime for weeks 1–2, 300 mcg for weeks 3–6, then 300–500 mcg from month two. It describes the first step as a conservative dose to assess tolerance.
Starting low and stepping up is a common approach in compounded peptide prescribing. [needs citation] Whether it is the right approach for you is a question for the clinician writing the prescription, and the schedule a seller advertises is not the schedule you will necessarily be given — several sellers say the prescriber sets it after intake.
Why the dose is almost always at night
Twenty-five of the ninety pages say to inject at bedtime, at night, or in the evening. Sermorelin is a growth hormone–releasing hormone analog: it prompts the pituitary to release growth hormone rather than supplying growth hormone directly, and the body’s own largest release happens during sleep, so evening dosing is meant to work with that rhythm rather than against it.

Six of the ninety pages carry anything that resembles a literature citation anywhere on them. None of the five that print a dose is among the six.
What we won’t print
A recommended dose. We have no verified figure for a starting dose, a maximum dose, a milligram-per-kilogram basis, or a dose adjustment for age, weight or kidney function, and we are not going to invent one. The five figures above are what five companies advertise, which is a fact about those companies.
There is no FDA-approved sermorelin product marketed in the United States, so there is no approved label to read a dose off. [needs citation] Thirty-seven of the ninety sellers say on their own pages that what they dispense is compounded and not FDA-approved.
