A warm welcome to MT bro.
Clen/ECA alternate 2 weeks can be run for 12 weeks in total dosing the clen as shown here:
T5 (I assume you mean the dorian yates supplement) is a standard otc ECA supp. Personally, I prefer to make my own ECA using the core ingredients as shown on the ECA 'sticky'.
Be aware though, these aren't magic pills. Of far more importance is diet & cardio.
