doses that are too high can result in what is called thyroid storm... you can set yourself up for a nice dirt nap with a few flowers

The only thing 25mg of t3 gave me was diarrhea 4-5 times a day. :/

Be careful brother. If you go to high day goodbye to the thyroid which will devistate your energy metabolism and many other things. But from my knowledge you should have DEFINATELY felt 25mg.

50mg a day is considered a therapeutic dose in studies done on the effects of T3 supplementation in normal individuals with depression related ailments. Hyperthyroidism or dosing with T3 can have an effect on your pulse pattern; particularly, a rise in systolic blood pressure. It's a bounding type of pulse, and not really a racing pulse like you ran a mile, but a harder stronger pulse. Body heat increase will only happen in some individuals usually at doses above 75mg, but it is not reflective of an increase in metabolic rate it is simply correlated.

Hypothyroidism which is a deficiency in T3. I have heard directly from an endocrinologist accounts for only 5-10lbs of fat in a patients. So, it should reason that dosing with T3 will only at most help you lose 10lbs of fat, and that is only at your natty body weight. All bets are out the table when dosing with AAS you might lose more or less, but if you have a low fat content already the law of diminishing returns should follow that you would only stand to lose very little, if any, fat when dosing with T3 or T4.

Also, T3 is cheap as hell, and isn't a highly controlled substance. It's pretty readily available. I really doubt it's fake even if it's from a peptide company.
