What blood tests do I need for CJC-1295 and Ipamorelin?

At minimum, test IGF-1, fasting glucose, and a basic metabolic panel. IGF-1 is the primary marker showing whether your GH peptides are working. Add thyroid panel and fasting insulin for a complete picture.

How much should IGF-1 increase on GH peptides?

Most users see IGF-1 increase by 30-100% from baseline over 6-12 weeks. The exact response depends on the peptide, dose, and individual factors. If IGF-1 hasn

Why isn't my IGF-1 going up on GH peptides?

Several factors can blunt IGF-1 response: poor sleep, high stress/cortisol, low thyroid function, inadequate protein intake, or suboptimal peptide quality. Blood work helps identify the blocker—check cortisol and thyroid if IGF-1 isn

Is high IGF-1 dangerous?

Very high IGF-1 (above age-appropriate ranges for extended periods) may carry theoretical risks. That
