i also gained weight off T3 alone, but pretty slowly and concerningly it also burned muscle tissue up. i wasnt using cypro or other things but was using vitamin d3 daily, maybe magnesium some vitamin k and random vitamins/minerals like b vitamins or magnesium zinc. i gained about 10 pounds on the scale in 2 months, but i probably lost 5 pounds muscle so in reality probably gained 15 poundsCypro with T3? So you take a downer (cypro) which kills histamine and lowers dopamine at high enough doses and thus increases appetite and then you take T3 which is supposed to stimulate neurotransmitters like dopamine, noradrenaline, and histamine and also stimulate the metabolic rate and increase calories burned.
You are taking 2 things that are fighting/opposing each other, cypro is winning because you are gaining weight. You cant raise the metabolism because of cypro ******* with your neurotransmitters and "stress" hormones which need to go up when you take T3 but they can't.
T3 does not get you fat it easily can drop fat off the body, its probably other things you are taking causing issues preventing it from working properly like the cypro.
Also increased estrogen is normal from T3, T3 raises all hormones.
apparently t3 alone can do this in some people, i never tried out t4/t3 combo but i use forefronts dessicated thyroid now. dont notice much good or bad from it. it apparently does have some silica in each capsule
