LEVEL 4 Complete Guide to Peptides
KAIAN R&D Team | |
Peptide combinations involve synergy and antagonism. Excellent multi-peptide formulations require deep scientific understanding.
Different mechanisms = synergy
Signal + enzyme-inhibiting peptides achieve 1+1>2.
Receptor competition
Same-receptor peptides compete and diminish effects.
3-layer approach
Layer 1 (immediate): Neuropeptides. Layer 2 (medium): Signal. Layer 3 (long-term): Enzyme-inhibiting. Immediate + lasting results.
Vitamin C & Retinol
Vitamin C (low pH) may degrade peptides — use AM/PM separately. Retinol compatible but needs stabilization.
