Hi there is allsorts of sites on the internet selling medications but nobody knows how safe they are and if they are the real thing! Even if they are safe you might have a bad reaction to them, Prozac is an SSRI and have carries side effects, it can make some people suicidal.
If you are feeling depressed post again and we can help.
Should you be doing that? You should see a doctor first. Meds should only be taken in consultation with your doctor.
