Hi there, i had planned to do a course of sustanon back in march of this year, i was going to use 250mg per week and do an 8 week course with the middle 2 weeks going up to 500mg. unfortunately tho, i had to take an urgent trip overseas for business 3 weeks in. i therefore quit the course and i still have 7ml left in the ampule which has been stored in a cool, dark place since. I would like to use these now, possibly a 5 week course with weeks 3 and 4 at 500mg and the rest at 250. would this be a problem?? do you think the sus will still be OK?? this is my first cycle and even after only 3 weeks i could see a huge difference, 4kg back in march!!! unfortunately most of the size has gone now due to not running the sus properly but i can see that the muscle is still there and will pump up in volume very quickly!! anybody able to help out?? thanks!!
