Ipamorelin10 mg

What it is

Ipamorelin is a synthetic pentapeptide, Aib-His-D-2-Nal-D-Phe-Lys-NH2, developed at Novo Nordisk from the growth hormone releasing peptide series. It acts at the ghrelin receptor and was described as the first growth hormone secretagogue selective for growth hormone release. It has been researched in endocrinology and, later, in gastrointestinal motility.

How it works

Ipamorelin is a selective growth hormone secretagogue studied for GH release with minimal off-target effects.

GHS-R

Binds the ghrelin receptor

Ipamorelin acts on the growth hormone secretagogue receptor, the same receptor the hormone ghrelin signals through.

Selective

A narrow signal

Unlike earlier secretagogues, ipamorelin is studied for releasing growth hormone without meaningfully raising cortisol or prolactin.

Pulsatile

Keeps the natural rhythm

Research frames ipamorelin as preserving the pituitary's pulsatile release pattern rather than overriding it.

Key benefits

  • Lyophilized powder, reconstituted for repeatable preparation.
  • COA-verified identity and purity, batch by batch.
  • Research-use plans built around a compound-specific question.

Laboratory research only. Not for human or veterinary use.

What published research is studying

Early human data
  • Selectivity of growth hormone release relative to ACTH, cortisol, prolactin, LH, FSH and TSH
  • Pharmacokinetics and the shape of the growth hormone response in healthy volunteers
  • Recovery of gut motility after bowel resection (phase 2 postoperative ileus trial)
  • Longitudinal bone growth and bone mineral content in rodent models

Human data amount to one pharmacokinetic study in healthy volunteers and one phase 2 trial that missed its efficacy endpoint. The rest is animal work.

Key research findings and references

Key research findings

In conscious swine, ipamorelin released growth hormone with potency similar to GHRP-6. It did not raise ACTH or cortisol above the levels seen after GHRH, even far above its ED50.

Raun K et al., Eur J Endocrinol 1998

In healthy male volunteers studied at five escalating 15-minute infusion rates, kinetics were dose-proportional and the terminal half-life was about 2 hours. Growth hormone peaked once, at roughly 0.67 hours.

Gobburu JV et al., Pharm Res 1999

In adult female rats dosed for 15 days, longitudinal tibial growth rate rose dose-dependently from 42 to 52 micrometres per day. Total IGF-I and bone turnover markers were unchanged.

Johansen PB et al., Growth Horm IGF Res 1999

Published study duration

  • Phase 2 postoperative ileus trial: dosing from postoperative day 1 to day 7 or hospital discharge (NCT00672074).
  • Rat longitudinal bone growth study: 15 days of dosing with tetracycline labelling on days 0, 6 and 13 (Johansen 1999).
  • Rat bone mineral content study: 12 weeks of continuous subcutaneous infusion in 13-week-old females (Svensson 2000).

Research endpoints

  • Peak plasma growth hormone, ED50 and Emax
  • Plasma ACTH, cortisol, prolactin, LH, FSH and TSH as selectivity measures
  • Terminal half-life, clearance and volume of distribution
  • Time from first dose to tolerance of a standardised solid meal
  • Longitudinal bone growth rate and bone mineral content by DXA

Research handling

Full handling guide
  1. 01

    Lyophilized, sealed, batch-numbered

    Each vial ships as a freeze-dried powder under an inert seal, tied to the batch on its Certificate of Analysis.

  2. 02

    Store cold and dark

    Unopened vials are kept refrigerated at 2-8°C away from light. Reconstituted material is stored refrigerated and used within the window the research plan defines.

  3. 03

    Reconstitute with bacteriostatic water

    The included bacteriostatic water is added slowly down the vial wall and the vial is swirled, never shaken.

  4. 04

    Research use only

    Supplied for laboratory research. Not for human or veterinary use. Handle with the personal protective equipment the laboratory requires.

Before you order

What ships in the box?

The vials selected, plus a free supply kit with every vial: one 3 ml bacteriostatic water, ten 0.5 ml syringes and ten alcohol swabs per vial, and the uu.life research handling card.

How does volume pricing work?

The price per vial depends on how many vials of the same strength are on the line. 3-4 vials take 5% off, 5 or more take 10% off. The discount is applied automatically and shows on the product page, in the cart and at checkout.

Is every batch tested?

Yes. Every batch is tested by an independent laboratory for identity and purity, and the Certificate of Analysis is linked from this page and the lab-testing library.

How fast is delivery?

Orders are typically dispatched within 1-2 business days and arrive across most of Europe in 3-5 business days, tracked, in discreet packaging. Orders over €250 ship free, and Shipping Protection can be added at checkout.

Is this for human use?

No. Every product is sold for laboratory research only and is not for human or veterinary use.
