T3 is a manager of the metabolism for energy producing from food or stored substrates like fat, muscle, and glycogen. Taking T3 significantly increases the uptake of nutrients and also the rate at which they are burned for energy, by increasing the activities of the enzymes involved. Everything is working harder, therefore more fuel is needed to supplement this increased work rate. For this reason, taking T3 will increase your body’s energy demands.
The recommended dosage is between 25-100 mcg/day, since PSL come at 50mcg this means you can break them in half if needed to achieve the bottom rate. There are two approaches to dosing T3 that I recommend.
Two different approaches could be used to cycle T3 --- In the 1st approach, the goal is to attain an ongoing edge in fat loss or to help maintain a near-personally-ideal body composition. T3 dosing is very low, preferably 12.5 mcg/day but in some cases as much as 25 mcg/day. At the lower end of this range, classically thyroid testing will show no detectable suppression even with extended use. At the higher end, moderate suppression is sometimes seen, but results are superior to when T3 is not taken, and the suppression reverses rapidly upon discontinuing T3 use. In the 2nd approach, the goal is to attain a quite extensive rate of fat loss, at the known cost of inducing thyroid suppression. The dosage is about 50 mcg/day, but in some cases can be as high as 75-100 mcg/day. Such use is preferably not ongoing, but only for a limited period of time such as 8-12 weeks, though there’s no exact requirement for timeframe.
From what I have seen, you can achieve a great deal of fat loss with T3, and as long as the doses aren’t abused you can have little to no side effects. Carefully measure and monitor yourself, like any new substance and you may just find your new favorite substance to add whilst cutting!
