HGH vs Sermorelin

HGH delivers the finished growth hormone molecule directly. Sermorelin is a GHRH analog that nudges your own pituitary to release more of your natural GH. Different lever, same axis.

HGH
Sermorelin
Tagline
Pharmaceutical-grade somatropin (direct GH)
GHRH analog — endogenous pulse amplifier
Mechanism
Recombinant human growth hormone — binds the GH receptor directly and drives hepatic IGF-1 production.
29-amino-acid GHRH fragment that signals the pituitary to release more of your own GH, preserving natural pulsatility.
Half-life
~2–3 hours systemic; downstream IGF-1 effect lasts ~24 hours
~10–20 minutes
Typical dose
1–4 IU daily, AM or split AM/PM, sub-q
300 mcg = 6 units, PM (10mg vial + 2 mL BAC)
Primary use
Body composition, recovery, IGF-1 elevation research
Natural GH support, sleep depth, gentler body-composition research
Stack fit
Pairs with IGF-LR3, MOTS-c, and recovery stacks. Generally not run alongside Sermorelin/CJC/Ipamorelin (redundant signaling).
Often paired with Ipamorelin for layered GHRH + GHRP signaling.
Side-effect profile
Water retention, joint stiffness, transient insulin sensitivity changes reported at higher doses.
Mild flushing or injection-site response; pulsatile dosing limits supraphysiologic exposure.
Best for
Researchers wanting direct, predictable GH exposure rather than pulse amplification.
Researchers preferring the body's own pulse pattern over direct hormone delivery.

When To Pick Which

◆ Pick HGH when

Direct, higher-magnitude GH research effects and faster IGF-1 elevation.

◆ Pick Sermorelin when

Gentler pulse-preserving approach, lower side-effect ceiling, sleep-anchored dosing.

◆ Run them together when

Generally not stacked — overlapping signaling. Pick one lever at a time.

FAQ

Is HGH stronger than Sermorelin?

Yes in magnitude — HGH is the finished molecule. Sermorelin amplifies your own pulses, which is more physiologic but lower ceiling.

Can I stack HGH and Sermorelin?

Not typically — they overlap. Most protocols choose one path.
