i just got levels back from june 20th and they were 5 and they were undetectable before that. so the lower dose 0.125 per kilo is working but i wonder if it will go higher??? people who went off the drug because of reactions their levels went up almost instantly back to predrug levels . so i wonder if my dose is too low. i only have 1 1/2 weeks left on the drug then i have to take a holiday(time off drug) before i start the extension. the extension will last until the drug is fda approved and availble bby prescription. they hope that durning the trial i will be able to give the shot myself instead of being given by a nurse like it is now.
