T3 is a very effective compound for aiding fat loss, but has serious side effects when overdosed. With proper care, it’s an easily-cycled compound. Because T3 has limited stability, it’s best sourced from quality pharmaceutical products, with a second choice being Third World generics or relatively-fresh powder which has been carefully measured. Liquid products can lose potency rapidly and therefore are not preferred.
Interaction of high serum T3 with IGF-1
High levels of T3 reduce levels of IGF-1, which can reduce anabolic effectiveness of GH, but does not change fat-loss effectiveness of GH.
This effect causes some to view T3 as relieving side effects of GH; actually, what is occurring is the T3 is making the same dose of GH produce less IGF-1 in the body than usual. It would be more efficient simply to reduce dose of GH to a personally-suitable level.
The effect of blunting GH effectiveness is particularly pronounced when T3 dosage is greater than 50 mcg/day, and seems unnoticeable if present at all at dosings such as 25 mcg/day.
