Many practioners have gone to "out of the conventional box" healing. I've worked with integrative MD's for many years and chiros too who work with Muscle Testing and work with Standard Process products. Many SP products contain animal glandulars etc. I've taken many of them over many years and even right now take Ligaplex II which contains several bovine extracts. SP has been around for more than 50 yrs, maybe close to 100 yrs and are in Wisconsin. Anyway,

I've completed 2 months on Sphingolin and a lot of the the burn/tingle on my thigh are gone. I'm going to stay off Sphingolin and see if the burn/tingle returns...but will stay with Inosine since I bought more of a supply.

I have more a "beef" with pharma drugs and the damage I and some loved ones have been thru. I won't get on that soapbox.

Maybe the burn will not return w/o Sphingolin, I'll find out. The Inosine label reads: Nerve Growth Factor.

These two were recommended by a naturopath.
