About Sermorelin

A 29-amino-acid GHRH analogue studied for stimulating natural pituitary growth hormone release in a physiologic pulsatile pattern.

Research dose ranges

  • Dose: 100–500 mcg per administration
  • Frequency: 1× per day
  • Route: subcutaneous
  • Half-life: ~0.25 hours
  • Cycle: 12 weeks on / 4 off

Research protocols typically administer 100–500 mcg subcutaneously once daily at bedtime to align with the natural nocturnal GH surge. Fasting prior to injection is recommended in most protocols to avoid blunting of the GH pulse.

Storage

Store lyophilized vials at 2–8°C. Once reconstituted, refrigerate and use within 30 days. Protect from light and freezing.

Sermorelin calculator FAQ

How do I use the Sermorelin calculator?+

Confirm your vial size in mg (default 2), set the diluent volume in mL (default 2), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard Sermorelin reconstitution?+

Most Sermorelin research protocols reconstitute a 2 mg vial with 2 mL of bacteriostatic water, yielding 1000 mcg/mL.

What syringe should I use for Sermorelin?+

U-100 insulin syringes are standard for Sermorelin subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the Sermorelin calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
