Ipamorelin 10mg

Ipamorelin comes as 10mg of freeze-dried research compound in a crimp-sealed glass vial. In short, it’s a growth hormone secretagogue. It’s meant for lab and analytical work only.

Ipamorelin purity and COA

Freedom Diagnostics, an independent US lab, tested Ipamorelin for Onyx Research using HPLC-UV for purity and mass spectrometry for identity. The certificate sits in the gallery next to the vial photos.

About Ipamorelin

Ipamorelin is a five-amino-acid growth hormone secretagogue, Aib-His-D-2Nal-D-Phe-Lys-NH2, developed at Novo Nordisk in the 1990s. It acts on the ghrelin receptor (GHS-R1a) on pituitary cells.

It was the first compound in its class shown to release GH selectively, without the rise in cortisol and prolactin that earlier GHRPs caused.

How Ipamorelin works

Ipamorelin mimics ghrelin at the growth hormone secretagogue receptor (GHSR-1a) in the pituitary and hypothalamus. Activating that receptor triggers a GH pulse.

Older secretagogues like GHRP-6 also raised cortisol, prolactin and appetite. This compound is much more selective, which is why it’s the usual choice when GH release is the only thing being studied.

Research findings

Raun and colleagues described it in the European Journal of Endocrinology in 1998, reporting that even at doses far above those needed for GH release, it didn’t raise ACTH or cortisol in pigs.

It later went into human trials for post-surgical ileus, a stalled gut after abdominal surgery, but didn’t progress to approval.

How Ipamorelin compares

In one line, the peptide is a selective ghrelin receptor agonist that releases growth hormone in pulses. The closest alternatives work differently:

• Sermorelin is the first 29 amino acids of GHRH, the shortest fully active piece
• CJC-1295 No DAC is a GHRH analog with four substitutions that slow its breakdown
• Tesamorelin is a stabilized GHRH analog with trial data on visceral fat
• IGF-1 LR3 is a longer-lasting IGF-1 analog that binding proteins mostly ignore

GHRH analogs and ghrelin receptor agonists hit the pituitary through two separate receptors, and IGF-1 LR3 acts further down the same axis. Every one of them is in stock in our growth hormone peptides.

When your order arrives

Each vial carries the black and white Onyx Research label with the compound, the amount, 99% purity and the research-use line. Check that the name and amount match your order and that the cap and crimp are tight.

Look for a dry powder. Loose pieces are fine. Wet or discolored material should stay out of your work, so contact us with a photo.

A one-line note per vial is enough: date received, date mixed and how much diluent went in.

Mixing Ipamorelin: a reconstitution chart

Concentration is simple division: the 10mg in the vial over the volume of water you add. Here’s the 10mg vial at three common volumes:

• Add 1mL: 10mg/mL (1,000mcg per 0.1mL, or 10 units on a U-100 syringe)
• Add 2mL: 5mg/mL (500mcg per 0.1mL, or 10 units on a U-100 syringe)
• Add 3mL: 3.33mg/mL (333.3mcg per 0.1mL, or 10 units on a U-100 syringe)

Bring the vial up to room temperature and clean the stopper with an alcohol pad. Inject the bacteriostatic water against the glass wall, not onto the powder, and swirl slowly until it’s clear. Shaking whips up foam and can damage the chain.

Storage and stability

Put sealed the peptide vials in the freezer at -20°C if you won’t use them soon. A few days on a shelf during transit does no harm to dry powder. Once you’ve added water, the vial lives in the fridge at 2 to 8°C for up to about four weeks.

Store mixed vials upright, so the liquid stays off the rubber stopper.
