I found posts that cautioned that combining J-Herb and APF would "dilute" the effects of both if given together.  I couldn't find any other cautions in the archives or files for APF.  My suggestion would be to contact your source....i..e.......Mov-Ease/MyBestHorse and Auburn Labs to ask for a list of possible contraindications.
