The "T3 causes catabolism" sentiment is one that is vastly exaggerated on AAS boards. To have this occur at any reasonable amount would require absurd levels of exogenous T3 and/or an absolutely horrendous dietary design...
I agree. And this is quite surprising really.
In this regards, there was a member Buselmo (apparently knowledgeable and acknowledged by few other experienced members) who used to post on getbig but stopped dont know why....his post is interesting.

T3 eats up muscle? LOL!
when you lose 10 lbs of sub-q water, and 10 lbs of glycogen... and your neck looks thinner (which is what most people notice immediately and start telling you you lost a lot of weight) THAT DOES NOT MEAN YOU LOST MUSCLE!!!!
look... here's something you should do... get off the sauce... for a couple of muscle... look at how shitty you start looking... once you get skinny, pile on fat in the wrong places, and lose muscle... get on a ton of T3 and some juice... and look at what happens... then you can assess what it does!
NEVER JUDGE IF YOU LOST MUSCLE BY IF YOU LOST FUCKING WATER!
180 mcg T3, 240 mcg Clen, 90 mg ephedrine and i gained fucking muscle...
2 days after going off the T3, clen, and ephedrine and loading up on carbs... i gained a good fucking 16 lbs and was the biggest I ever was at this body fat.
the problem with assessing if T3 makes you loss muscle or not is that when you're a blowfish and are holding so much water your sock marks last for a month... you go on the thermos and especially T3 and lose a lot of water and start burning up Glycogen like a mother fucker... you look flatter, you lose fullness, but you lean out like fuck... when you're on T3 and you think you're losing muscle, don't you notice that your muscles turn into rocks when you flex them? instead just being "pumped and bloated"?
T3 doesn't make you lose muscle... i don't care what anyone says...
I used to think that, and i'd "see it" happen when i was on 50 mcg T3 and i start panicing... it was all bullshit... it's not muscle, it's glycogen and water. once i got that through my thick head and said "so fucking what if i look just a little thinner? i don't give a shit"... a couple of months later, I was as lean as fuck and i gained muscle. so don't give me that shit that T3 makes you lose muscle... and don't tell me the usual "ppl are different"... It's not a coincidence that i used to "lose muscle" when i listened to this shit and believed it, and fucking gained muscle when i said "fuck it... it's bullshit"
