ok so i started my cycle today with 2iu jintropins that expired back in may 07 but have been in the fridge.. so about 5 mins after injection i was sitting at my computer and started to get a metallic taste in my mouth and got a lil sweaty, lite headed and tingly, lasted about 15 mins...it was nothing severe and i didnt eat any carbs for breakfast so i dont think it was glucose level. but its just weird i never experienced this sensation from gh b4...could it be becuz it was so old?? i have fresh gh i just figured id run the jins first cuz they were older...anyone know what this can be from??
