with all do respect to you reinheart the 2 weeks on and 2 weeks off is a very common answer to this question. there are many people out there, such as myself, who need more details because if they are going to do something they are going to do it right. i have seen multiple dosage choices including the following:
***THIS IS FOR A TOTAL OF 6 WEEKS ON CLEN AND T3. IF YOU ARE ONLY DOING 4 WEEKS THEN SKIP THE MIDDLE WEEK THAT I HAVE WRITTEN DOWN AND CYCLE OFF THE CLEN***
clenbuterol
day1-3: 40mcg
day4-6: 60mcg
day7-8: 80mcg
day9-14: 100mcg
2 weeks off
for the next two weeks continue 100mcg daily
2 weeks off again
for last 2 weeks on cycle reverse week one, example below
day1-6: 100mcg
day7-8: 80mcg
day9-11: 60mcg
day12-14: 40mcg
cytomel(t3):
day1-2: 1/2 a pill
day 3-4: 1 pill
day 5- 30: 1.5 pills
im not even sure if this is correct cause i've heard the recommended dosage should be 120 mcg of clenbuterol and could go up to 140 but do not exceed 140. i guess it would depend on the results your trying to get but an actual chart would be great help
