I would avoid tyramine, it can give you wicked headaches....migraine style bro. Tiratricol aont too peachy either, it can lead to massive weight loss yes, but it will make you feel lethargic and give you diarhea. These arn't going to make you feel like working out much.
I would Combine the T3 (a great thyroid stimulator) with yohimbine (a better more pure/potent yohimbe derivative) with say....20-25 mg ephedrine. This may elevate your HR a bit, but should provide excellent fat loss when combined with good diet and cardio. Good Luck Bro!
PS- You could safely add 200mg caffeine to this stack for improved results.
