Sermorelin
WELL RESEARCHEDGHRH 1-29 analog | Growth hormone releasing hormone
Overview
What is Sermorelin?
Sermorelin is a synthetic 29-amino-acid analog of human growth hormone releasing hormone (GHRH). It was originally FDA-approved for growth hormone deficiency in children. Despite its withdrawal in 2008 for manufacturing reasons, it maintains an excellent safety profile and stimulates the natural, pulsatile production of growth hormone.
Key benefits
FDA-proven efficacy, maintains natural GH pulses and preserves pituitary function.
Mechanism of action
It stimulates the pituitary gland to release growth hormone naturally and in pulses, preserving physiological rhythms.
Quick start guide
What to expect
- Week 1-2: IGF-1 levels begin to rise, possible improved sleep and recovery.
- Week 2-4: noticeable body composition changes begin, more energy and well-being.
- Week 4-8: visible improvements in muscle tone, fat reduction and better skin quality.
- Week 8-12: sustained body composition improvements and optimal IGF-1 elevation.
- Month 3-6: maximum benefits, including muscle growth, fat loss and anti-aging effects.
Side effects & safety
- Monitor thyroid function: about 6.5% develop hypothyroidism requiring hormone replacement.
- Check IGF-1 levels monthly at first, then every 3-6 months long-term.
- Injection-site reactions occur in 16.7% of patients but are usually mild.
- Contraindicated in active cancer, pituitary tumors and pregnancy.
- Allergic reaction: rash, itching or swelling.
- Swelling, numbness or tingling in the hands (possible carpal tunnel syndrome).
- Symptoms of hypothyroidism: severe fatigue, weight gain or cold sensitivity.
- If you are pregnant, breastfeeding or planning a pregnancy.
Frequently asked questions
What is Sermorelin?
Sermorelin is a synthetic 29-amino-acid analog of growth hormone releasing hormone (GHRH). It was once FDA-approved for growth hormone deficiency in children.
What is Sermorelin researched for?
It is studied for GH stimulation, body composition, recovery and anti-aging.
How does Sermorelin work?
It stimulates the pituitary gland to release growth hormone naturally and in pulses, preserving physiological rhythms.
How long does Sermorelin take to work?
IGF-1 rises in 1-2 weeks, body composition improves in 4-8 weeks and peak effects are seen between 3 and 6 months.
What is the usual Sermorelin dose?
Most commonly 200-300 mcg per day, usually before bed. The schedule is set by a professional.
How is Sermorelin administered?
Subcutaneously, on an empty stomach and before bed to match the natural GH peak.
How is Sermorelin stored?
Refrigerated; the lyophilized powder lasts longer. See the storage guide.
What are the side effects of Sermorelin?
Mild injection-site reactions; with prolonged use it is advisable to monitor thyroid function.
Which peptides is Sermorelin combined with?
It is usually paired with a GHRP such as Ipamorelin to boost GH release.
What is the difference between Sermorelin and CJC-1295?
Sermorelin is GHRH 1-29 with a short half-life; CJC-1295 is a modified version that adjusts its duration.
Is Sermorelin approved?
It had FDA approval, withdrawn in 2008 for manufacturing reasons, and keeps a good safety profile.
