"i was prescribed fastin for weightloss . the prescription pills worked great not a single bad side effect i lost over 50 lbs in about 4 months.  it gave me energy to start working out and wow did my concentration for work improve .   however the pills were costly and given out in office only. so every month it was 40 for the dr visit and weigh in and another 40 for 1 months worth of pills .    when i was unable to afford this regimen i looked for cheaper alternatives. i got some over the counter bottle of fastin i bought 2 bottles.  these are unhealthy, way over caffinated crap! i had gotton very ill half way in to taking the first bottle and had to stop bcaz jitters, headache, paranoia racing heart !!! my advise pay for the real stuff."
