What it is
›
Sermorelin is a classic, gentle GHRH that supports natural GH, sleep, and recovery.
• Best for: a mild, well-studied GH boost
• Edge: a long track record in clinics
• Shorter-acting, so dosed nightly
How it works
›
It nudges the pituitary to release GH in a natural rhythm.
• Mimics GHRH, the natural GH signal
• Keeps GH release in natural pulses
• Gentle and self-limiting
Dosing and mixing
›
Reference tiers only. Track the dose you are already taking.
Low
100 mcg, nightly
FOR Gentle support or beginners
BENEFIT Often picked as the lower-exposure tier in GH and sleep discussions
Standard
200 to 300 mcg, nightly
FOR Sleep and recovery for most
BENEFIT The nightly range most often cited in sermorelin discussions
High
300 mcg, nightly, with a GHRP
FOR Stronger goals
BENEFIT People pick this combined tier when researching a GHRP alongside sermorelin
Schedule: Inject nightly before bed on an empty stomach.
Beginner ramp: Start at the standard dose, little ramp needed.
Mixing (reconstitution)
BAC water is bacteriostatic water, the sterile water you mix in.
A 5 mg vial with 2 mL BAC water is a common starting point.
