seven calculators, each doing one conversion by itself rather than asking you to trust a seller’s math: the reconstitution arithmetic, the trial dose scaled to your body weight, what a “starting at” price actually totals once the billing cycle and any required membership are counted, whether a prepaid term is the saving it is presented as, and what twelve months comes to at every seller whose price we hold. None of them recommends a dose or a seller — each computes what the numbers you enter imply, and shows the work.
Reconstitution Calculator
The single most consequential arithmetic a sermorelin buyer does: vial strength and bacteriostatic water in, exact units to draw on a U-100 syringe out, every step shown.
Open the calculator →Trial dose vs. marketed rangeDose-by-Weight Calculator
The one adult trial used 10 mcg/kg; sellers commonly market a flat 200-300 mcg nightly. See your own trial-equivalent dose next to that range — and which one is actually higher.
Open the calculator →What 'starting at' hidesCost Calculator
Enter a price, how often it is billed, the term, any up-front fee and any required membership to get the true cost per month and the real first-year cost — checked against every published sermorelin price we hold.
Open the calculator →Per vial, into per monthVial Duration Calculator
Some sellers price by the vial, not the month, and a vial is not a month. Enter strength, your dose and how often you inject to get doses per vial, days of supply and the cost per month that makes it comparable.
Open the calculator →Tablet against needleTablet vs Injection Price
The tablet ought to be cheaper. Most sellers that publish both charge exactly the same, and one charges more — for the route with no human trial behind it. Compare any two prices against the whole distribution.
Open the calculator →When longer costs morePrepay Break-Even Calculator
A prepaid term is sold as a discount and is sometimes not one. Enter a monthly rate and a prepay offer to get the effective rate, the month it draws level, and a flag when the longer plan is the dearer one.
Open the calculator →The whole roster, annualizedAnnual Cost Comparison
Every seller with a published price, sorted by what twelve months of it really costs — 28-day billing counted as thirteen charges, required memberships added on, and the sellers whose price we could not settle named rather than left out.
Open the calculator →Or read the boards
For questions a single conversion can’t answer — which seller, which format, whether the evidence holds up — these boards answer them with the working shown.
Every published price, lowest first
Ranked strictly on the standing month-to-month rate — never an introductory month, a first-order coupon, or a prepaid quarter divided out to look smaller. If a seller's homepage and its checkout disagreed, we used the one you would be billed on month two.
Open the board →Which format?Oral against injectable, priced separately
The comparison a calculator would get wrong. Sellers price the two formats independently, the gap runs $40 to $60 a month, and it does not run the same direction every time — one seller charges more for its oral product than for its own injection.
Open the board →Who prescribes it?Plans, not one-off checkouts
The sellers whose own pricing describes an ongoing prescribed relationship — a multi-month ladder, an auto-refill, a membership — rather than a product page that assumes you already have a script.
Open the board →Check the claimWhat the trials actually measured
One placebo-controlled adult trial, 19 people, five months, unreplicated since — positive on lean body mass in men only, null on sleep in both sexes, and beaten by real growth hormone in the one head-to-head that exists.
