Sermorelin / Ipamorelin Blend: dosing, reconstitution and evidence

Sermorelin — the first 29 amino acids of GHRH — paired with Ipamorelin. The mildest of the GH blends, and the one most likely to come from an actual pharmacy rather than a research vendor.

Also known as Sermorelin Ipamorelin, Serm/Ipa, sermorelin ipa blend

Sermorelin / Ipamorelin Blend quick start

Route
SubQ
Typical dose
300–1,000 mcg total blend per dose — check the stated split on your label
Frequency
Once nightly before bed
Half-life
Sermorelin about 10–20 min, Ipamorelin about 2 h. Very short, which keeps the GH pulse close to physiologic.
Cycle
3–6 months is typical, since the effects build slowly.
Vial sizes sold
15mg or 9mg
These are the numbers people actually run, drawn from the published record and from what the community has settled on over time. Educational reference, not medical advice — a starting point to work from, and one you can adjust as you learn how you respond.

What people actually run

The entry-level GH blend, and the one most telehealth clinics prescribe. Gentler than CJC/Ipa and easier to get legitimately.

This is accumulated community practice — years of real-world use across a large number of people, converging on numbers that work. It is not a controlled trial, and for most compounds here no such trial exists or is ever likely to. That makes this the most reliable dosing signal available, and it is a good deal better than guessing.

What to expect

Most people tolerate Sermorelin / Ipamorelin Blend well. Here is what is worth knowing going in, so nothing catches you by surprise.

The gentlest option in this category and the easiest to obtain through legitimate channels. Sermorelin's very short half-life means timing matters more than dose — take it at night, on an empty stomach, and give it three months before judging. Worth a conversation with your doctor first if you have any malignancy history.

Known interactions

Interactions involving Sermorelin / Ipamorelin Blend's drug class that DoseIQ screens for. Each one cites where it comes from — an FDA label section or the published record — because an interaction warning you can't trace is just noise.

Caution GH peptides push blood sugar against your diabetes medication

Growth hormone raises glucose and insulin resistance — it works directly against glucose-lowering medication.

What to do: Fasting glucose and HbA1c are worth tracking; medication doses sometimes need adjusting. Your prescriber should know GH peptides are in the picture.

Reconstitution guide

Sermorelin / Ipamorelin Blend ships as a lyophilised powder and gets mixed with bacteriostatic water before use. How much water you add sets the concentration, which sets how many syringe units make up each dose. One unit on a U-100 syringe is 0.01 mL — the tables below do the arithmetic for the vial sizes you are most likely to be holding.

Often supplied already reconstituted by a compounding pharmacy. If it arrives as powder, a 15 mg vial is usually 9 mg sermorelin to 6 mg ipamorelin.

Standard steps

  1. Inspect the vialConfirm the label and that the powder cake is intact. Do not use a cracked or compromised vial.
  2. Let it reach room temperatureSitting out for a few minutes reduces condensation inside the vial when the seal is broken.
  3. Disinfect both stoppersWipe the compound vial and the bacteriostatic water vial with a fresh alcohol swab and let them air-dry.
  4. Draw the bacteriostatic waterUse a sterile syringe to draw the volume you have chosen from the reconstitution table.
  5. Add the water down the vial wallInject slowly so it runs down the inside wall rather than spraying directly onto the powder. This limits foaming.
  6. Dissolve gentlySwirl or roll the vial between your hands until the cake dissolves. Never shake — agitation damages peptide bonds. The solution should end up clear.
  7. Label and refrigerateWrite the reconstitution date and concentration on the vial. Store at 2–8°C. Do not freeze.
