Alternatives to ECA, T3 and Clen

[Billy_No_Mates]

I seem to be very intolerant of stimulants. I used an EC stack last year. The dose was 2tabs x 3 times a day. After 3 months I still couldn't handle more then 1tab in the morning, I'd be buzzing all day. Therefore I don't expect to be any different on T3 or Clen!

Are there any good non-stimulant alternatives?

Thanks in advance
