Sermorelin/Ipamorelin Blend Calculator

The Sermorelin/Ipa blend pairs Sermorelin (a 29-amino-acid GHRH analog) with Ipamorelin (a selective GHRP). Users who prefer Sermorelin's profile over CJC-1295 may choose this variant. A common formulation is 2 mg of each for a 4 mg total vial, reconstituted with 2 mL of bacteriostatic water.

Components in the Sermorelin/Ipamorelin Blend

Each peptide in this blend has its own individual calculator page with factual information on vial sizes, reported half-life, and storage. Compositions vary by vendor — the mg ratios above are defaults based on commonly cited formulations.

  • Sermorelin — A 29-amino-acid truncated GHRH analog that binds pituitary GHRH receptors to stimulate endogenous growth hormone release.
  • Ipamorelin — A selective pentapeptide growth hormone releasing peptide that activates the ghrelin receptor to stimulate pituitary GH release.

How to use this calculator

The Sermorelin/Ipamorelin Blend calculator handles two dose-targeting modes:

  1. Target total blend dose — "I want 2 mg of the blend per injection." The calculator returns the draw volume and reports how much of each component you're getting at that draw.
  2. Target specific component — "I want 250 mcg of BPC-157 specifically." The calculator back-calculates the draw from that component's concentration, and reports incidental amounts of the other components delivered at the same draw.

If your vial's stated total mg differs from the sum of component mg values (common on vendor labels — rounding, copper-ion mass, excipients), the calculator flags the mismatch and uses the component sum as the authoritative total for math purposes.

Sermorelin/Ipamorelin Blend FAQ

What is the Sermorelin/Ipa Blend? +
A combined vial containing Sermorelin and Ipamorelin. Similar concept to the CJC/Ipa blend but using Sermorelin (the unmodified GHRH fragment) in place of CJC-1295.
How is this different from CJC/Ipa? +
Sermorelin has a shorter half-life (~10–20 minutes) than CJC-1295 no DAC (~30 minutes) and is the unmodified GHRH 1-29 fragment. Published pharmacokinetics differ slightly; mechanism is very similar.
How do I compute a dose? +
Use the calculator above — same math as any blend. Enter component mg, water, and target dose; the calculator returns the draw + per-injection amount of each peptide.
