T3/Cytomel carbolic?

Have any of you guys using T3/ cytomel noticed any catabolic effects on your muscles? Or lack of progression in muscle building? I know it's supposed to be catabolic, but not sure at what dosage, and not sure exactly how much corresponding testosterone you have to inject to compensate for this. Any ideas?
 
Never noticed anything like this when I tried t3. Had to stop, it was giving me terrible maxillary tori from bruxism even at low doses.

I presently taking 25 MCG in the morning and 12 MCG in the afternoon. I feel it actually helps me grow more muscle.
 
When I was on 2.5 grains of NDT, my free T3 came back at 7.3 (2.3-4.2), and I definitely noticed catabolism at this dose, but obviously my free T3 was way too high. When it was that high, it was impossible to gain muscle, and I think I lost a little muscle. It was very noticeable. I also looked very flat.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
