Sermorelin vs Tesamorelin
Which should you choose? Here's what you need to know.
The short answer
Both are GHRH analogs, but tesamorelin is more potent and is FDA-approved for reducing visceral belly fat in HIV patients. Sermorelin is gentler, more affordable, and widely used for general anti-aging.
Sermorelin
Growth HormoneSermorelin is a 29-amino-acid GHRH analog and one of the original GH-stimulating peptides. It produces a gentle, natural GH release that mimics natural pulsing. It's popular in anti-aging protocols for its favorable safety profile and lower cost.
Choose Sermorelin if:
You want an affordable, well-tolerated option for general GH support, anti-aging, or sleep improvement.
Tesamorelin
Growth HormoneTesamorelin is a 44-amino-acid GHRH analog enhanced with a molecular group that makes it more resistant to breakdown and more potent. It's the only GH peptide with FDA approval — specifically for reducing visceral belly fat in HIV-associated lipodystrophy.
Choose Tesamorelin if:
You specifically want to target visceral fat reduction, need a more potent GH stimulus, or want the confidence of an FDA-approved peptide.
