There are various ways of using t3, this includes the traditional pyramid. I have run this protocol ramping up to 125mcg for up to 8 weeks before.
Up until about a year ago this was the only way I took t3
However, about a year ago I decided to try a protocol that Bill Roberts recommended a while back, (and I believe some other bros use, P22 I'm looking in your direction) 12.5mcg daily. I have run this for up 2 months and have noticed little to no suppression and very good fat loss.
I wish I had tried this method earlier, but I was too set in my ways. I like this dosing protocol and generally use it in addition to prop/tren/winny and HOT-ROX.
Here is an excerpt from a question he responded to regarding t3 dosing:
"I'd also like to see lower thyroid doses than most other people are arguing. Brock Strasser tells me about guys who have theories that involve taking one mcg/day for every pound of bodyweight, so a 200-lb guy would be taking 200 mcg/day, or 8 tabs.
I don't think much of those doses. These guys are in the flat part of the dose-response curve for sure. I mean, a full replacement dose is only 25 mcg.
What you have to consider is whether taking 200 mcg/day gives 8 times the extra fat loss of 25 mcg/day, in effect causing the user to lose an extra 8-16 lb per week instead of an extra one or two? No, and it doesn't give four times the results either, or even twice the results. The dose response curve has flattened out long before reaching this dosage level.
Fifty mcg/day will cause somewhat more fat loss than 25 mcg, though it may be bothersome for many users and will shut down natural thyroid production almost completely. Seventy-five mcg/day will enhance the effect slightly, but beyond that, the curve's pretty much flat.
Personally, I radically advocate going in the opposite direction ? I like to see doses as low as 12.5 mcg/day. Here, natural thyroid production isn't reduced much. You get most of the benefits, and almost none of the adverse effect.
Using this dosage, you should be able to lose 3 lb of fat per week, or close to it, with no problem? if all else in the diet and exercise program is good.
Taking the 12.5 mcg/day dose level actually results in about 50 mcg of drug in your system, because T3 (Cytomel) has a long half life and your system doesn't contain just the amount you took today, but also about three times more than that left over from previous days.
For this reason, I'd take a 50 mcg loading dose the first day (if I knew I handled T3 well), and then maintain that level with 12.5 mcg/day after that. If it were my first use, though, I'd let levels build up slowly instead of taking the loading dose.
If you want to lose fat faster than 2-3 lb per week, expect to lose LBM and expect it to be a brief crash program, like Brock's Fit Fast Diet. You could, of course, crash off 10 lb or so in the first week, but most of it would be water and glycogen loss. Sustaining a fat loss of 6-8 lb week after that, as your friend says you can do, isn't realistic.
Since strength is important to you, I'd keep calories up ? 12 cal/lb/day, figuring your desired weight is 200 lb, so for you, that equals 2400 calories. Keep protein up, and either use an isocaloric diet or a cyclical or targeted ketogenic diet.
I'd definitely do far less aerobics than mentioned, no more than 2 hours per week. Keep protein up to at least 200 g/day. MD6, added caffeine, and optionally added ephedrine will help. Don't combine the MD6 with the clenbuterol, though. That could be a very bad mistake, since both the clenbuterol and the yohimbine in MD6 have some action on the heart.
Keeping androgen levels up or elevated above normal would help greatly, especially when using thyroid hormone ? use of the substance tends to cause a lot of LBM losses if androgens aren't used."
