Ipamorelin | 6mg
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue created through structural refinement of the earlier peptide GHRP‑1. It is recognised as the first growth hormone–releasing peptide (GHRP) receptor agonist designed with high selectivity, showing a specificity for growth hormone stimulation comparable to that of endogenous growth hormone‑releasing hormone (GHRH). In biochemical and cellular research environments, ipamorelin functions as an agonist at the ghrelin/growth hormone secretagogue receptor (GHSR‑1a), which is expressed on pituitary somatotrophs. Compared with earlier GHRPs such as GHRP‑2 and GHRP‑6, ipamorelin displays a distinct selectivity profile: experimental work has shown that, at concentrations effective for stimulating growth hormone release, it does not trigger adrenocorticotropic hormone (ACTH) or cortisol secretion. This characteristic makes ipamorelin a useful research compound for isolating growth hormone–specific signalling pathways without concurrent activation of the hypothalamic–pituitary–adrenal (HPA) axis. In controlled animal studies, ipamorelin has also been associated with dose‑dependent increases in longitudinal bone growth.

How we ship it
Every pre-mixed vial leaves the UK cold and arrives in a plain box. Refrigerate on arrival at 2–8 °C.
Chilled
Vials travel with frozen gel packs inside a sealed foil pouch, which holds temperature for roughly seven days in transit.
Insulated
The pouch sits inside a wool-lined envelope, so the cold chain survives a normal courier journey.
Discreet
Plain outer box with no branding and nothing on the label that names the contents.
Same-day dispatch
Order before 3pm GMT, Monday to Friday.
Free over £100
Tracked UK delivery, next working day.
2–8 °C on arrival
Refrigerate as soon as the parcel lands.

Ipamorelin: research FAQs
- What is Ipamorelin?
- Ipamorelin is a synthetic pentapeptide belonging to the growth hormone secretagogue (GHRP) family, developed through structural refinement of the earlier peptide GHRP-1. It is recognised as one of the first growth hormone-releasing peptide receptor agonists designed with high selectivity for growth hormone stimulation. It is supplied strictly as a reference compound for in-vitro laboratory research use only.
- What is Ipamorelin studied for in research?
- In biochemical and cellular research, ipamorelin has been investigated as an agonist at the ghrelin/growth hormone secretagogue receptor (GHSR-1a) expressed on pituitary somatotrophs. Preclinical work has reported a distinct selectivity profile, with growth hormone stimulation observed at concentrations that did not trigger ACTH or cortisol secretion, making it a useful tool for isolating growth hormone-specific signalling without activation of the hypothalamic-pituitary-adrenal axis. Controlled animal studies have also reported increased longitudinal bone growth in the models examined. These are laboratory research observations only, not established effects in humans.
- Is Ipamorelin legal to buy in the UK?
- Ipamorelin is legal to buy and possess in the UK for laboratory research purposes. It is not a licensed medicine and cannot be sold for human or veterinary consumption. Every vial ships labelled for in-vitro research use only.
- What purity is your Ipamorelin, and is it lab-tested?
- Our Ipamorelin is verified at 99%+ purity by HPLC analysis. The figure printed on each batch's Certificate of Analysis is the actual value recorded in the laboratory for that batch, not a generic marketing claim. It is synthesised and dispatched from our own UK facility rather than imported or repackaged by an overseas re-shipper.
- Does Ipamorelin come with a Certificate of Analysis?
- Yes, a batch-specific Certificate of Analysis (COA) ships with every order. You can also view sample COAs in our COA library before buying, so you can review the testing documentation in advance. The COA records the HPLC purity and identity data for the specific batch supplied.
- How is Ipamorelin supplied, stored and handled for research?
- Ipamorelin is supplied as a pre-mixed solution in a sealed vial — no reconstitution step is required. Its batch Certificate of Analysis records the appearance as a clear liquid. Refrigerate at 2°C–8°C, keep the vial sealed and away from light, and do not freeze it: freeze-thaw cycling can damage peptides already in solution. Handling in the laboratory should follow standard aseptic research practice.
