@ Boffhead - yeah know exactly what you mean. I train 5-6 times a week, am in good shape according to doc who did full medical 4 weeks ago. After a heavy night on the meph 2 weeks ago, found myself getting out of breath after walkin up 2 flights of stairs and much weaker in the gym. Whether this is down to dehydration, lack of sleep is debatable....however something about this shit just doesn't feel right.
Also experienced the dizzy spells, feels kinda like when you' ve got a bad head cold and sinuses are bunged up.
I admit, the dunt off this stuff was great but its now at the stage where the negative side effects by far outweight the pluses, I for one will be giving this a miss come Jan 2010.
