About
Sermorelin is a synthetic peptide analogue of the first 29 amino acids of human Growth Hormone Releasing Hormone (GHRH). It is used to stimulate the pituitary gland to produce and secrete more Growth Hormone.
Mechanism of Action
Sermorelin binds to GHRH receptors on the pituitary gland, stimulating it to produce and release Growth Hormone. It has a short half-life, which results in a pulsatile release of GH that mimics the body's natural patterns, making it a safer alternative to exogenous HGH.
Key Benefits
- Stimulates natural Growth Hormone production
- Improves lean body mass and reduces fat
- Enhances sleep quality
- Supports anti-aging and vitality
Clinical Research
Sermorelin is FDA-approved for diagnosing GH deficiency and for treating it in children. It is widely used off-label in anti-aging and wellness clinics to restore youthful GH levels in adults.
Potential Side Effects
Side effects are generally mild and can include injection site reactions (pain, redness, swelling), flushing, and headache. Because it stimulates the body's own production, it is less likely to cause major side effects associated with high-dose HGH.
Usage & Dosage
Administered via subcutaneous injection, typically at night to coincide with natural GH release cycles. Dosages generally range from 200mcg to 500mcg per day.
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).
