Shredded fat fast with T3—metabolism felt turbocharged. Lost weight but had to monitor muscle loss. Great for cutting when diet is on point.

Energy and fat loss were unreal, but came with muscle loss if not careful. Stack with gear or high protein to hold onto gains.

Took 25mcg to start—heart rate climbed and appetite increased. Dropped body fat in 2 weeks. Needed to taper off slowly to avoid crash.

Helped cut stubborn fat that cardio couldn’t touch. Muscle loss hit hard until I added test. Watch your dosing—it’s very sensitive.

Powerful for fat loss, but it doesn’t discriminate—burns fat and muscle. Great when stacked properly. Side effects manageable at low doses.
