T3 Question

[megamatt68]

I've read some about T3, and have come across the same claim on different boards about how T3 doses at 12.5 mcg per day will increase muscle protein synthesis while on cycle. My question(s) is, even if there is any truth to this claim, isn't 12.5 mcg lower than what a healthy adult thyroid will output (25mcg approximately)? Wouldn't this slow the thyroid down because it is less than one's own endogenous production? Or is there an additive effect, in other words, it works alongside your endogenous production?

It would initially raise total t3, and would only down-regulate if you were exceeding your energy requirements or not eating enough carbs.

Rebound from t3 use is a fast comeback with no real big issues

Yes it will increase protein turnover rates, it is useful on cycle

Thanks for the response, I guess I will have to experiment on cycle to assess whether low doses are worth it for me or not.

Biggest thing to beware of is BP, it will already be up on cycle so don't start adding any t3 until you are sure it is managed as it will get higher

I use T3 regularly in my cycles for MPS purposes. Most guys I know who use T3 for this purpose run 25-50 mcg. Per their feedback, I know 25 mcg works well. However, I only have experience running 50 mcg (which also works well) because I've never cared to break up my little pills up.

Your natural T3 production will be effected at these doses, which may mean production slows down or stops. This is dose and duration dependent. One unorthodox but effective method to minimize this effect (and aid faster recover) is to not run T3 every day. I've ran 2 different protocols: 2 on, 1 off and 5 on, 2 off. These methods keep your thyroid from adapting. I prefer the 5 on, 2 off because this fits my schedule better because I usually workout 4-5 days during the week and take the weekends off.

Every time I've ran one of the protocols above, recovery has been fast and easy. Once I tried the traditional ED protocol and recovery was much slower and I felt like 'death' for about a week. I also recommend Now's Thyroid Energy supplement as a T3 PCT.

One more thing that you won't hear or read about...
Try overlapping or staggering your T3 with your AAS or other stims. Meaning, end your T3 run with 2-4 weeks left on your AAS cycle. This allows you to recover in a 'super' state with elevated androgens. Never stop your AAS, T3, Stims, etc. all at the same time.

My blood work just came back. On 25mg t3, t4 was extremely low and tsh was normal. Also running tren.
