With the dhea i'm not sure of the amounts as it is only available here from certain drs who have special government approval to import it & although my dr does import it he's put me on the others first & is waiting on test results before adding dhea.
He likes to put people on one med (even natural ones) at a time so as to see if there are any problems & then go on from there.
Also he starts people at lower doses depending on age/weight/other meds/health issues etc. So I would suggest that you ask a health store owner or contact biosynergy.Com which is where my dr orders from & get advice from them or from them as to where to go for advice.
Like you ibroprofen & naproxen etc kill my stomache!!!!!!!!!!!!!!!!

actually so do mersyndol but I can take the cheaper brands of mersyndol (i think it's because they don't use the yellow die that is used in mersyndols - it's weird but that's supposedly the only difference between mersyndols and the cheaper brands!!).
Please take the calcium (highest possible dose) & the glucosamine & chondroitin tablets, start at one a day & increase to 2 after about 2 weeks. Check toowith the health shop to see if they recommend any others (then before you buy check it on the net!!.).
