Description
What Is Ipamorelin? (In Plain English)
Ipamorelin is a very short man-made chain of five building blocks that fits one specific docking spot on cells in the pituitary gland, like a key cut for a single lock. When it docks, the gland releases a pulse of growth hormone. Scientists study Ipamorelin in animals and cell cultures because it is unusually picky about which lock it opens.
Ipamorelin 5mg — Research Overview
Ipamorelin is a synthetic pentapeptide with the structure Aib-His-D-2-Nal-D-Phe-Lys-NH2, developed as a growth hormone secretagogue. It acts in the published literature as an agonist at the growth hormone secretagogue receptor type 1a (GHS-R1a), the same receptor engaged by ghrelin, driving pulsatile growth hormone release from pituitary somatotrophs. It is frequently described as one of the more selective GHS-R1a ligands, with animal studies reporting comparatively little disturbance of cortisol, prolactin, and ACTH relative to earlier secretagogues such as GHRP-6.
Primary Research Areas
- GHS-R1a receptor pharmacology — investigated in vitro for binding selectivity and receptor activation profile
- Growth hormone pulsatility — studied in animal models for the amplitude and timing of GH secretion
- Secretagogue selectivity comparisons — referenced in the literature against GHRP-2, GHRP-6, and hexarelin for off-target hormone response
- GHRH co-stimulation models — examined in combination study designs with GHRH analogues in preclinical research
- Bone and connective-tissue animal research — a research area exploring GH-axis mediated endpoints in rodents

Why Researchers Source Ipamorelin from Dissolv Labs
Dissolv Labs is a research-supply company based in Southern California. Orders are picked, packed, and shipped domestically from our SoCal facility, so most U.S. laboratories see short transit times and no international customs delay.
Every vial ships as a complete kit. Each Ipamorelin vial is paired with its own bacteriostatic water reconstitution vial, so the material arrives ready to prepare in the lab without a separate diluent order. Compounds are supplied lyophilized in sealed, labeled vials with lot identification, and analytical documentation is available on request.
Ipamorelin — Frequently Asked Questions
What is Ipamorelin used for?
Ipamorelin is supplied strictly as a research chemical for in vitro and laboratory research applications. The literature studies it as a selective GHS-R1a agonist in growth hormone secretion, receptor pharmacology, and secretagogue-comparison models. It is not for human or veterinary use.
What is the difference between Ipamorelin and CJC-1295?
They act at different receptors. Ipamorelin is a GHS-R1a agonist in the ghrelin-receptor family, while CJC-1295 is a GHRH analogue acting at the GHRH receptor. Because the two pathways converge on the somatotroph, preclinical studies often examine them together to characterise additive or synergistic GH release.
Why is Ipamorelin described as selective?
Published animal work reports that Ipamorelin stimulates growth hormone release with comparatively little concurrent rise in cortisol, ACTH, or prolactin, in contrast to earlier hexapeptide secretagogues. That profile is the main reason it appears so frequently as a reference compound in GHS-R1a selectivity studies.
Where can I buy Ipamorelin 5mg research peptide?
Ipamorelin for sale at Dissolv Labs ships domestically from Southern California in sealed, lot-identified 5 mg vials. Each order arrives as a complete kit with a bacteriostatic water reconstitution vial included, and analytical documentation is available on request.
Research Use Only
Ipamorelin is sold exclusively as a Research Use Only (RUO) chemical.

Exact quantity and concentration are listed in the product title and variant options above. The figures above are release specifications — the measured result for your particular lot is stated on its Certificate of Analysis.
Documentation & Testing
Every batch is tested before release. Testing covers four checks: identity by mass spectrometry, purity by HPLC against a ≥99% release threshold, content verification against the labelled mass, and batch release tied to a specific lot number.
To request the Certificate of Analysis for your vial, email us with your order number or the lot number printed on the label. We do not gate documentation behind a form or a purchase.

Handling & Storage
Lyophilized peptides are relatively stable during transit. Arriving at room temperature is not cause for concern — the cold pack is a margin of safety rather than a pass/fail condition.
Sealed vials of lyophilized material are typically stored refrigerated or frozen and protected from light. Handling protocols for a specific compound are determined by the researcher and their institution; we supply the material and its documentation.
Shipping & Returns
Orders placed before the daily cut-off are dispatched the same business day from Southern California in insulated packaging with ice packs. Tracking is issued at dispatch.
If a shipment arrives damaged, if vial contents appear inconsistent with the specification, or if the lot number on your vial does not match the certificate we provide, contact us and we will resolve it.
Because these are temperature-sensitive laboratory materials, opened vials cannot be returned to stock.
