While the T3 PCT will be beneficial after using T3, I agree with @muskate that it is not necessary to take T3 supplementation, as it will also eat up your lean mass, and may bring along quite some side effects. THerefore, better go with Cardarine GW-501516, which is non-hormonal, and will burn exclusively fat. What's more, Cardarine will even increase you lean mass, which is a huge advantage, and has no side effects at all.
