Sermorelin calculator
Sermorelin math uses the listed vial sizes on this card and the liquid you type. Concentration in mcg per mL is vial milligrams times 1000, divided by milliliters. A U-100 syringe has 100 marks per milliliter, so each unit is that concentration divided by 100. Example numbers so you can see the math: a 5 mg listing plus 2 mL of liquid. Change any number and the units change. Try the numbers. A research-market vial is not the same material used in a trial.

Units chart for listed Sermorelin sizes
U-100 math for listed Sermorelin sizes. Each cell is micrograms per syringe mark if you add that much liquid. The table does the same math as the calculator. It does not pick an amount for you.
| Listed vial | 1 mL liquid | 2 mL liquid | 3 mL liquid |
|---|---|---|---|
| 5 mg | 50 | 25 | 16.7 |
| 10 mg | 100 | 50 | 33.3 |
What is Sermorelin?
Research listings reuse the sermorelin name after the branded product left the market. A pulled approval does not automatically allow compounding or gray-market supply. The catalog records compounding as not established.
Growth-hormone-releasing-hormone analogue.
Regulatory status, dated 2026-10-09
Compounding
not established. Compounded products do not carry FDA product approval; legal eligibility is not established here.
Research
investigational. Human growth-hormone response studies; not proof of adult wellness or longevity benefit.
Sport
prohibited. WADA S2 lists this GHRH analogue.
What the cited papers actually measured
Older child and adult papers on Geref measured growth-hormone stimulation under medical supervision. Those plans belong to that product and era. PubMed 11297509 is one cited clinical-context paper. Current research-market 5 mg and 10 mg vials are not Geref. Sport status is unverified here. If you still have a printout from the Geref years, keep it as history and type the milligrams printed on the vial you hold now.
We mark the cited papers as C. That is our label for how strong those papers are. It does not say the compound works.
How long it lasts, how you store it, listed sizes
The catalog does not record a single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied.
Use the label on the vial you hold. Old Geref storage is not copied onto research vials.
Risks and mix-ups already on the record
- Safety is incomplete; absence of reports does not establish safety.
- Unknown or incomplete for research formulations; this is not a clearance for use.
- Unknown or incomplete; do not infer compatibility with medications or other substances.
People using PepBear often log: Existing clinician-directed records, symptoms and dated health measurements. Record missing data; trends do not demonstrate causation.

Questions people ask
If Geref was approved, is sermorelin approved now?
A pulled product is not a live approval for every later vial. Check current FDA product databases. This catalog does not treat sermorelin research listings as approved drugs.
Can I use an old Geref amount in the calculator?
You can type any mass you want. The tool will still only return syringe math. Old label amounts are not suggested here.
How many units is a listed Sermorelin vial after you add water?
Units = (amount in mcg ÷ (vial mg × 1000 ÷ water mL)) × 100 on a U-100 syringe. Enter the three numbers. The chart shows the same math for each listed vial size and 1, 2 or 3 mL of liquid.
Why flag amounts under 5 units?
A U-100 barrel is easy to misread below about 5 marks. That is a measuring warning. The page does not tell you to take more.
