CJC-1295 + Ipamorelin vs IGF-1 LR3
Which should you choose? Here's what you need to know.
The short answer
CJC-1295/Ipamorelin stimulates your body to produce more GH naturally, which then raises IGF-1 through normal pathways. IGF-1 LR3 skips all that and delivers growth factor directly.
On 9 Oct 2026 Peptide Compare tracked 44 vendors selling CJC-1295 + Ipamorelin, cheapest in stock $2.90 per mg at Bio Pepz, and 46 selling IGF-1 LR3, cheapest $20.83 per mg at Bio Pepz.
CJC-1295 + Ipamorelin
Growth HormoneThe CJC-1295/Ipamorelin stack works upstream — it tells your pituitary to release more GH, which your liver converts to IGF-1. It's a physiological approach that preserves natural feedback loops.
Choose CJC-1295 + Ipamorelin if:
You want a natural, feedback-preserving approach to raising GH and IGF-1 — safer for long-term use.
IGF-1 LR3
Growth HormoneIGF-1 LR3 is a synthetic, long-acting growth factor that bypasses the GH system entirely. It's approximately 2.5x more potent than natural IGF-1 and acts directly on muscle tissue.
Choose IGF-1 LR3 if:
You want direct, potent growth factor stimulation and understand the additional risks of bypassing your body's natural GH regulation.
