What to Expect
- Muscle fullness and pumps within the first 2 weeks
- Improved recovery — soreness clears faster
- Notable strength gains by week 4
- Possible mild hypoglycemia sensation — have carbs nearby
Stack tip: Commonly stacked with BPC-157 for recovery or CJC+Ipamorelin for GH pulse amplification.
Do
- Eat a carb-containing meal within 30 minutes of injection
- Monitor for hypoglycemia symptoms, especially early on
- Keep cycles short — 4 to 6 weeks per run
Don't
- Run longer than 6 weeks without a break — receptor desensitization occurs
- Inject into the same site repeatedly
- Use without medical supervision if diabetic
