when your injecting 1.5 - 2grams of sustanon per week . stable blood levels are not an issue . personally I like to use sustanon 500 to get these levels . but I'll still shotgun it an throw in some Test e and test prop with various injections.
the point is to get to 10,000+ ng/dl test levels, and if it drops off 40% cause you missed an injection, so what your still at 6000 ng/dl
