I have been seeing a Doc for weight loss and he prescribed phentermine for me but only out of the "office" pharmacy.Never by prescription to have filled.I feel nothing from these.I am starting to think these are not the real deal.I have researched phent. on line and these look nothing like the ones I've found online.They have no imprints or anything.How can I find out exactly what these are and If I'm being scammed!
