02Weekly timeline

Week 1

IGF-1 receptor activation begins. Enhanced nutrient partitioning and recovery.

Weeks 2-3

Noticeable muscle fullness and recovery speed. Satellite cell proliferation increasing.

Week 4

Peak effects. Complete the cycle and take 4 weeks off to prevent receptor desensitization.

03Who this is documented for

Advanced users seeking direct IGF-1 pathway activation for muscle growth beyond what GH secretagogues provide.

04Reported outcomes

Direct IGF-1 receptor activation,20-30 hour bioactive half-life,Systemic muscle growth,Enhanced recovery,95% reduced IGFBP binding

05Important notes

Monitor blood glucose levels,Short 4-week cycles ONLY,Do not exceed 50 mcg/day,4-week break between cycles required,Advanced users only
