Newbie here, I started Glenmark just over 2 weeks ago 1mg. Dosing 1 x week, bumped with grapefruit this last time. Not sure what I am supposed to feel / observe and when to indicate it is working.


Most people don’t feel any different on Rapamycin.


I take Pfizer Rapamune and Zydus Siromus. Zydus seems to be stronger in that I get more side-effects.

Very interesting and thanks for sharing this! It has been a little hypothesis that I have that different brands can have more or less side-effects. What type of side-effects do you get more of when taking Zydus?

All of the side effects I have had are from Zydus. I started Rapammune and moved on to Zydus. Then I developed side effects. I spent 5 weeks on the Pfizer brand. 4 weeks at 1 mg + GFJ and the last week 2 mg + GFJ. Zydus was 2 mg + GFJ weekly after that.


My insurance company changed went from Cigna… Accredo-- Dr. Reddy Sirolimus to now Anthem Careion-- Greenstone Rapamune
