Hey guys, I’ve heard that doses of T3 under 25mcg/day don’t actually suppresse natural thyroid production and provide benefits by adding to existing thyroid production. Anyone tried this? Could you do this for weeks at a time or would exogenious(or whatever the word is) T3 eventually shut you down no matter what? I’ve seen doing low doses for a two week period recommended in Chemcial Muscle Enhancement, but would you be in suppressionville if you did it for 4 weeks?
All personal experience and/or knowledge welcome.
