What are the most common mistakes with Hexarelin?
The most common Hexarelin mistakes are running longer than 4 weeks (rapid receptor desensitization); treating it like a daily-driver; skipping the prolactin/cortisol bloodwork. Most issues people run into come down to protocol and expectations, not the compound itself. Going in informed matters here because human evidence for Hexarelin is limited.
Common Hexarelin mistakes
- Running longer than 4 weeks (rapid receptor desensitization)
- Treating it like a daily-driver
- Skipping the prolactin/cortisol bloodwork
