Buy Ipamorelin UK – 10 mg vials
Looking for Ipamorelin UK? Ultra Peptides supplies Ipamorelin as a lyophilised research compound in 10 mg vials (10 mg for £19.99), dispatched from the UK the same working day when you order and pay before 2 pm. A selective pentapeptide ghrelin-receptor (GHS-R1a) agonist used in growth-hormone secretion research.

What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide and one of the most selective growth-hormone secretagogues described. It binds the ghrelin receptor GHS-R1a on pituitary somatotrophs.
It is supplied as a 10 mg lyophilised powder in a 3 ml vial.
Ipamorelin research overview
Researchers who order Ipamorelin UK from us typically work in the following areas. All of the work summarised here is preclinical – cell-culture and animal-model research – and is not evidence of any effect in people.
Receptor selectivity
Early pharmacology work showed Ipamorelin stimulates GH release without the marked ACTH and cortisol increases seen with GHRP-6 or GHRP-2, which makes it a cleaner tool for isolating the GH axis.
Gastrointestinal motility models
Because ghrelin receptors are also expressed in the gut, Ipamorelin has been used in animal models of gastrointestinal motility.

Purity and independent lab testing
Every vial of Ipamorelin UK is supplied at a minimum of 99% purity, measured by HPLC. We send batches to independent laboratories and publish the certificates on our lab reports page as they are issued. If you need the analysis for the batch you receive, email us your order number and we will send it.
Peptides are synthesised to the published sequence, lyophilised and sealed under controlled conditions, then stored cold and away from light until they are packed for dispatch.
Reconstituting and storing Ipamorelin
Ipamorelin arrives as a dry, lyophilised powder. Most researchers reconstitute it with bacteriostatic water, adding the diluent slowly down the inside of the vial and swirling gently rather than shaking. Use our reconstitution calculator to work out the concentration for the volume you add.
Unopened vials keep best frozen at −20 °C, or in the fridge at 2–8 °C for shorter periods, always protected from light. Once reconstituted, keep the solution refrigerated and avoid repeated freeze–thaw cycles – splitting it into aliquots helps. Our storage guide covers shelf life in detail.
Often researched alongside: CJC-1295 (no DAC).
Laboratory handling checklist for Ipamorelin
- Let the sealed vial reach room temperature before opening, so moisture does not condense on the powder.
- Wipe the rubber septum with 70% isopropyl alcohol and work on a clean surface.
- Add the diluent slowly down the inside wall of the vial and swirl gently until the powder has dissolved – do not shake.
- Label the vial with the concentration, the date of reconstitution and the batch number.
- Keep reconstituted solutions at 2–8 °C, protected from light, and use them within the stability window of your protocol.
- Record lot numbers in your lab notebook so results can be traced back to a specific batch.
