Aight, to start off with I've taken thermogenics (sp?) for the past 6 yrs or so so that may have some effect?

day1-20
day2-80
day3-120
day4-120

a buddy of mine is splitting the same supply as me. He is at 40 mcg and feeling the effects; so its not bunk gear...

Is it possible that I'm getting the good without the bad? I'm debating on upping it to 160mcg/day... but still researching that.

Input would be appreciated.
