Ipamorelin overview
Ipamorelin (NNC 26-0161, CAS# 170851-70-4) is a synthetic pentapeptide classified as a selective growth hormone secretagogue receptor (GHSR-1a) agonist. NexPept supplies it as a lyophilized research reference standard for GHSR-1a receptor binding assays, selectivity profiling against ghrelin receptor subtypes, and in vitro secretagogue signalling studies. Not for use in any living organism.
Every lot is independently tested by a third-party analytical laboratory before it is listed, and results are confirmed by high-performance liquid chromatography and mass spectrometry.
Ipamorelin is used as a peptide tool compound in preclinical in vitro settings. Published work has examined its behaviour in GHSR-1a receptor binding assays, selectivity profiling against other ghrelin receptor subtypes, endocrine signalling pathway models, and structure–function research within the secretagogue peptide family.
As a defined 5-amino-acid sequence with a selective binding profile, it is used in controlled laboratory environments to isolate GHSR-1a-specific signalling from the broader secretagogue pathways activated by less selective compounds. Lot-to-lot consistency matters for this kind of work, which is why NexPept publishes a per-batch purity figure for every compound it lists.
This compound has not been authorized by Health Canada for any therapeutic, clinical, or human use.
Research Use Only. All products are intended solely for laboratory research use and are not for human or veterinary use. By purchasing, the buyer agrees to use these products in compliance with all applicable laws.
Frequently asked questions
What testing does each batch go through?
Identity and purity are confirmed by high-performance liquid chromatography and mass spectrometry before a lot is listed. If a lot has not been tested, it does not go on sale.
What class of compound is Ipamorelin?
A synthetic pentapeptide classified as a selective growth hormone secretagogue receptor (GHSR-1a) agonist. Supplied as a lyophilized powder and handled as a peptide reference standard, not as a formulation.
How does Ipamorelin differ from CJC-1295?
Ipamorelin is a short 5-amino-acid sequence that selectively activates the GHSR-1a receptor, while CJC-1295 is a longer GHRH analogue acting through a separate receptor pathway. Researchers studying secretagogue signalling sometimes examine both compounds to distinguish GHSR- from GHRH-receptor-driven effects.
What physical form does it arrive in?
A white to off-white lyophilized (freeze-dried) solid, sealed in a single vial. Net quantity is 10mg. No preparation, reconstitution or handling instructions are supplied; those are determined by qualified personnel under your own institutional protocols.
All products are intended for laboratory research use only.
Not for human or veterinary use.
