I got my hands on some synthroid, tabs 150mcg, 175mcg, and 200mcg, can someone with firsthand experience guide me in what dosing and length of cycle to go along with the cutting cycle that I am already on, Sus, tren E, and Equiy. Diet 2000 cals. daily and cardio 45 min. X 4-5 days weekly. 6'1" 220lbs. 11% Bf. Am an experienced gearhead, but with not with thyroid stuff.
basically there are two different issues with synthroid, 1) half life of ~7days vs ~1 for t3. this makes dosing very tricky. 2) T4 converts to T3 ~4units of t4 to 1unit of T3. in short you need to take four times as much and allow for the blood plasma build up difference due to the much longer half life, this sounds like it is right up your alley.
i have never had much luck with t4 and prefer amour thyroid a combination of t4/T3. with the diet and exercise you post you should lose weight readily. for me, the low and slow approach to thyroid supplementation has worked best. do not look to it as a magic bullet but rather as an extra tool.
