This sermorelin dosage chart shows how Olympia’s compounded Sermorelin Acetate 0.9 mg/mL is typically dosed: how much to take per day, how to convert mcg to mL and syringe units, and when to inject. If you’re new to the medication, start with our overview of Sermorelin injections.
Sermorelin dosing is always set by your prescriber. Use this guide to understand your prescription, not to replace it.
Important note on sermorelin dosage
Important: Sermorelin dosing is individualized and will vary depending on patient needs and the plan created with a licensed healthcare professional. Use the dosage chart below as an educational overview only.

Sermorelin dosage per day: when and how often to take it
The dosing guide above lists a typical plan as 300 mcg once nightly, 60 to 90 minutes after your last meal. In practice, “once nightly” usually means one injection in the evening each day, based on the schedule your clinician has selected.
If it helps to visualize weekly totals (as an example only):
- 300 mcg per night x 7 nights = 2,100 mcg per week (2.1 mg per week)
Your prescriber may keep the dose consistent or adjust it based on your goals, your response, and your overall protocol.
Some prescribers pair sermorelin with other therapies as part of a broader protocol. Olympia also offers an NAD+ & Sermorelin bundle. If you’ve been prescribed the bundle, follow the directions on your bundle’s label, since the chart above applies only to standalone Sermorelin Acetate 0.9 mg/mL.
This schedule is recommended because Sermorelin is designed with support of the growth hormone-releasing hormone (GHRH) in mind. In the body, growth hormone is released in pulses, and these peak during the night. Administering Sermorelin before bed is intended to help synergize with your body’s own schedule of growth hormone release.
How to read the chart: sermorelin dosage in mcg, mL, and units
Many dosing charts show mcg (the medication amount) alongside units (the markings on a common U-100 insulin syringe). This helps patients measure volume more easily.
Here is how the math works for Sermorelin Acetate 0.9 mg/mL:
- 0.9 mg/mL = 900 mcg/mL
- 300 mcg ÷ 900 mcg/mL = 0.333 mL (about 0.33 mL)
- On a U-100 syringe, 1 mL = 100 units, so 0.33 mL is about 33 units
Think of these steps as a simple sermorelin dosage calculator. Plug in your prescribed mcg and the vial concentration to find your mL and units.
Quick conversion tips (U-100 syringes):
- Units to mL: units ÷ 100 = mL
- mL to mcg (for 0.9 mg/mL): mL x 900 = mcg
Always verify two things before measuring: (1) your vial concentration on the label, and (2) the syringe type you are using. If anything looks different from this guide, pause and contact your prescriber or pharmacist.
Where to inject sermorelin: SubQ vs. IM
Sermorelin injections may be administered via subcutaneous (SubQ) or intramuscular (IM) injection, depending on the plan created by your clinician. Your prescriber may consider factors like your routine, comfort with injection technique, and how your overall protocol is structured.
Subcutaneous injections are commonly given into the fatty tissue of the abdomen or thigh, rotating sites each time. Your prescriber or pharmacist can show you the right sites and technique. See our step-by-step guide on how to give a subcutaneous injection.
Sermorelin dosage for muscle and fitness goals
People with fitness or body-composition goals often ask whether sermorelin is dosed differently. The dose is still set by your prescriber, and the chart above applies to Olympia’s 0.9 mg/mL injection whatever your goal. What often differs is everything around the dose: consistent nightly timing, sleep, nutrition, and training. For more on how sermorelin fits into a supervised training plan, read Sermorelin Acetate and its role in fitness training.
Who is sermorelin prescribed for?
Patients who are experiencing low levels of human growth hormone (HGH) may be prescribed Sermorelin Acetate, though it can also be recommended for patients focusing on weight loss and athletic performance. Ultimately, your clinician can help determine whether Sermorelin fits your needs and how it should be dosed and scheduled.
Sermorelin is one of several peptides that interact with the growth hormone axis, and it’s often confused with others that work very differently. For a side-by-side look at how they compare, see our guide to sermorelin vs. ipamorelin, CJC-1295, and BPC-157.
Precautions and possible side effects
The most commonly reported side effects are injection-site reactions such as pain, redness, or swelling. Tell your provider about all medications, supplements, and health conditions, including thyroid conditions, before starting. Seek urgent care for signs of a serious allergic reaction. Full precautions are on the Sermorelin Acetate product page.
Storage and handling notes
Keep your vial refrigerated and protected from light, and always check the label before each dose.
