Which should you choose? Here's what you need to know.
Both stimulate growth hormone, but CJC-1295/Ipamorelin is a dual-mechanism stack producing stronger GH pulses. Sermorelin is a gentler, single-peptide GHRH analog — simpler and more affordable.
CJC-1295/Ipamorelin combines two peptides hitting different GH pathways for amplified output. It's the go-to stack for people who want robust GH elevation for body composition and recovery.
Choose CJC-1295 + Ipamorelin if:
You want the strongest GH response and are willing to manage a two-peptide protocol.
Sermorelin is a 29-amino-acid GHRH fragment that gently stimulates your pituitary's natural GH rhythm. It was FDA-approved from 1997-2008 and has decades of clinical use behind it.
Choose Sermorelin if:
You prefer simplicity, lower cost, and a gentler GH boost — especially for long-term anti-aging or sleep improvement.
Once you've decided which peptide fits your needs, here's how they compare on price and vendor options.
Our top-rated vendor for each, based on trust scores, purity testing, and price.
We re-check vendor prices continuously and score vendors on Finnrick blind-test results — samples bought anonymously and sent to a lab, not vendor claims. No vendor can pay to rank higher. See our full methodology.
