1st of all, next time order more than you need. As far as the problem at hand its already been answered that Cypionate is almost the same. However I saw answers like prop, tne and sustanon. Which in my opinion is very wrong. Yes test is test but your injection schedule is very diferent with those esters. Prop needs to be injected EOD , TNE needs to be every day and Sustanon is best at 3 days a week ( MWF). Im guessing you were using the E on an every 4th day injection ? Cyp is the only one you could run that way and maintain steady levels.
