Seems like most people think that the cause of sust flu is from the short acting esters, they say these symptoms are also possible with test prop itself as well as tren ace etc. I've ran prop with no flu like symptoms and I'm starting some sust this Monday, gonna run dbol at 40mg ed for 4 weeks and the sust at 750mg a week for 12 weeks, if I've had no symptoms with prop as stated above would you say I'm in the clear with sust? Also, anyone think the short ester theory is false?
