IGF-1 in Peptide Research: Why It's the Key Biomarker
IGF-1 is the primary endpoint for GH axis peptide research. This guide covers IGF-1 biology (GHR/JAK2/STAT5b), normal reference ranges, published IGF-1 elevation data for all major GH secretagogues, sampling timing requirements, confounders (nutrition, sex, age, stress), ELISA selection guidance, and a full research design framework for using IGF-1 as your primary endpoint.
Insulin-Like Growth Factor 1 (IGF-1) vs Growth Hormone: The Downstream Mediator Explained
A deep technical dive into the GH/IGF-1 axis: GHR/JAK2/STAT5b/IGF-1 hepatic synthesis, IGFBP-3 ternary complex, why IGF-1 is the standard proxy endpoint for GH secretagogue research, reference ranges by strain/sex/age, and critical confounders in endpoint design.
MK-677 vs Ipamorelin vs CJC-1295: Which GH Secretagogue for Your Research?
A comparative research guide to MK-677 (ibutamoren), ipamorelin, and CJC-1295 No DAC — covering mechanisms, published IGF-1 data, half-life differences, pulsatile vs continuous GH elevation, and a decision matrix for choosing the right compound for your study design.
