I have always been interested in vyvanse. I find the method used to make it a prodrug fascinating. I recently came across a much lesser known prodrug called benzphetamine which is not only a prodrug of dextroamphetamine but also dextromethamphetamine. I’m curious how one prodrug can break down into two different amphetamines. Unlike vyvanse it is only used for appetite suppression/weight loss/obesity. Has anyone tried this medication?
 
Didrex (Benzphetamine) is an AMAZING pro-drug compound……it’s actually listed at a lower CII level than Desoxyn (Methamphetamine) ……Benzphetamine / Biphetamine (1950’s Adderall) “Black Beauties” 20mg XR capsule and the two most highly desirable Dexamyl (d-Amph & Barbiturate) and the #1 Desbutal (d-Meth & Barbiturate)

Didrex (Benzphetamine) is very effective for bing eating / obesity management and probably off label for various reasons such as amphetamine addiction, antidepressant perhaps ?

Benzphetamine metabolizes into its main active metabolite d-Methamphetamine, then gradually would metabolize into its final active metabolite, d-Amphetamine…..it has a very long duration of action very similar to Vyvanse (Lisdexamfetamine) ……a gradual gentle onset and most likely reaches C-max in 3-4 hours (Methamphetamine) and lasts 12-16 hours approximately (gradually tapering off over the last 4 hours or so (roughly)

Id LOVE to have 100 tablets of Didrex (Benzphetamine) 50mg / 75mg tablets

It’s basically 100% pure pharmaceutical Dextro-Methamphetamine HCL
