About
Hexarelin is a potent, synthetic Growth Hormone Releasing Peptide (GHRP) that stimulates a strong release of Growth Hormone from the pituitary gland. It is also known for its potential cardioprotective effects.
Mechanism of Action
Hexarelin acts on both the pituitary and hypothalamic ghrelin/growth hormone secretagogue receptors (GHSR) to stimulate a robust and dose-dependent release of GH. It is one of the most potent GHRPs available for research.
Key Benefits
- Potent stimulation of Growth Hormone release
- Potential cardioprotective effects
- May increase lean body mass
- Supports recovery and repair
Clinical Research
Studies in humans have demonstrated Hexarelin's ability to significantly increase GH levels. Research has also explored its cardioprotective effects, suggesting it may help protect the heart from ischemic damage.
Potential Side Effects
Hexarelin can cause a more significant increase in cortisol and prolactin compared to other GHRPs like Ipamorelin. Desensitization can also occur with prolonged use.
Usage & Dosage
Typically administered via subcutaneous injection at a dosage of 100-200mcg, 1-3 times per day. Due to desensitization, it is often cycled in research protocols.
Peptide Storage
Best Practices For Storing Peptides
To preserve the integrity of laboratory results, proper storage of peptides is essential. Correct storage practices can maintain peptides for years and guard against contamination, oxidation, and degradation. If the peptides will be used immediately, short-term refrigeration under 4°C (39°F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks.
For longer-term storage (several months to years), it is preferable to store peptides in a freezer at -80°C (-112°F). Avoid repeated freeze-thaw cycles and do not use frost-free freezers, as temperatures can fluctuate widely.
Preventing Contamination
To prevent moisture contamination, allow the peptide to come to room temperature before opening its container. Minimize exposure to air; after use, reseal the container under an atmosphere of dry, inert gas (like nitrogen or argon) if possible. Peptides with Cys, Met, or Trp are especially prone to air oxidation.
Storing Peptides In Solution
The shelf life of peptide solutions is far less than that of lyophilized peptides. If peptides must be stored in solution, use sterile buffers at pH 5-6 and separate into aliquots to avoid repeated freezing and thawing. Peptide solutions are generally stable for up to 30 days when refrigerated at 4°C (39°F).
