mechanism · pending
The short copy still fits the pituitary gland's GHRH receptor, so it can trigger a normal growth hormone (GH) pulse.
dosing · pending
Most research-context protocols use 200-300 mcg once a night, by subcutaneous injection, about 3
regulatory · pending
It was FDA-approved in 1990 as a diagnostic agent and again in 1997 as a treatment for childhood growth hormone deficiency (brand name Geref).
safety · pending
Serono Laboratories pulled it from the market in 2008 for manufacturing reasons, not safety reasons.
regulatory · pending
As of June 2026, sermorelin still sits in FDA 503A Category 1 , which means licensed compounding pharmacies can legally prepare it.
dosing · pending
Common dose 200-300 mcg subQ nightly.
dosing · pending
Titration usually starts at 100 mcg.
dosing · pending
Reconstitution 3 mL bacteriostatic (BAC) water in a 10 mg vial gives 3 units per 100 mcg on a U-100 insulin syringe.
regulatory · pending
Regulatory status 503A Category 1 in June 2026 - still legally compoundable.
regulatory · pending
Sermorelin has historical FDA approvals but no current branded product.
dosing · pending
relin Dosing Protocol & Schedule Sermorelin dosing in research-context protocols centers on nightly subcutaneous (subQ) injections before bed.
dosing · pending
The FDA-era label set adult-context dosing at 0.2-0.3 mg per day (200-300 mcg).
dosing · pending
Modern community protocols use a similar range, with some practitioners titrating up to 400-500 mcg in selected cases.
dosing · pending
Higher doses do not always produce a bigger GH pulse.
dosing · pending
That feedback caps how much GH a single sermorelin dose can release.
dosing · pending
Typical Titration Schedule Sermorelin titration framework (research-context reference, not medical advice) Phase Initiation Time Weeks 1-2 Dose nightly 100 mcg Notes Check for injection-site reactions and any sleep changes.
dosing · pending
Phase Standard Time Weeks 3-4 Dose nightly 200 mcg Notes Common starting therapeutic tier in practitioner protocols.
dosing · pending
Phase Optimization Time Weeks 5-8 Dose nightly 300 mcg Notes Often paired with IGF-1 and thyroid labs at the 6-week point.
dosing · pending
Phase Elevated Time Week 9+ Dose nightly 400-500 mcg Notes Higher end if response at 300 mcg is not enough.

Phase Time Dose nightly Notes Initiation Weeks 1-2 100 mcg Check for injection-site reactions and any sleep changes.

imization Weeks 5-8 300 mcg Often paired with IGF-1 and thyroid labs at the 6-week point.
dosing · pending
Elevated Week 9+ 400-500 mcg Higher end if response at 300 mcg is not enough.
dosing · pending
These numbers come from FDA-era prescribing context for the 0.2-0.3 mg/day range and from published practitioner reviews.
dosing · pending
Adult anti-aging dosing was never validated by a large modern RCT.
dosing · pending
This is not a dosing recommendation.
dosing · pending
Dosing 30-60 minutes before bed lines sermorelin up with that pulse.
dosing · pending
Schedule Cycle length Pattern 3-6 months at a target dose Best for Most published practitioner reviews suggest reviewing labs at baseline, week 6, and week 12.
dosing · pending
rget dose Most published practitioner reviews suggest reviewing labs at baseline, week 6, and week 12.
monitoring · pending
Lab monitoring matters Standard practice is baseline labs (IGF-1 plus a thyroid panel), repeat at week 6, and again at week 12.
regulatory · pending
About 6.5% of FDA-era trial participants developed hypothyroidism, which is why thyroid checks were built into the original prescribing pattern.
dosing · pending
The math below assumes a default 10 mg sermorelin vial, 3 mL BAC water per vial, and 200 mcg per night.
dosing · pending
Sermorelin Vials (10 mg default) One 10 mg vial holds 50 doses of 200 mcg.
