Cortagen protocol FAQ
How long is a typical Cortagen protocol?
Standard Cortagen protocols run 10 weeks for a full Intermediate cycle. Beginner cycles compress to ~5 weeks for response assessment. Advanced cycles extend to ~13 weeks but require closer monitoring.
What's the safest dose to start a Cortagen cycle with?
The Beginner tier on this protocol starts at half the standard published dose. Hold 2-3 weeks to assess tolerance, then escalate to Intermediate dosing if no adverse signals.
Do I need to cycle off Cortagen?
Cycling depends on the compound's mechanism. Receptor-saturating compounds (most peptides) benefit from 4-6 week off-cycles between protocols to prevent downregulation. Non-saturating compounds (some healing peptides) can run continuously. The full Cortagen research profile covers this in detail; see the cross-links below.
Can I stack Cortagen with other compounds?
Stacking is common for synergistic effects, but each compound's mechanism, half-life, and route of administration matter. Use the BodyHackGuide stack builder + interaction checker to validate any pairing. The "Where to source" section below ranks vendors who carry Cortagen alongside complementary compounds in one shipment.
