What are the most common mistakes with GHRP-2 / GHRP-6?
The most common GHRP-2 / GHRP-6 mistakes are treating them as Ipamorelin equivalents, they have meaningful side effect differences; eating within 30 min of injection (kills the GH pulse); skipping cycle breaks. Most issues people run into come down to protocol and expectations, not the compound itself. Going in informed matters here because human evidence for GHRP-2 / GHRP-6 is limited.
Common GHRP-2 / GHRP-6 mistakes
- Treating them as Ipamorelin equivalents, they have meaningful side effect differences
- Eating within 30 min of injection (kills the GH pulse)
- Skipping cycle breaks
Bloodwork worth tracking
- IGF-1 baseline + week 8
- Prolactin if running >8 weeks (GHRP-2)
