Are there any reasons i should avoid switching from Test Cyp to Sustanon 6 - 7 weeks into my 12 week cycle? Im currently in week 4 taking 500mg Test C and 300mg EQ/ Week but im going to run out of test before my cycle ends. It may take too long to ship more test C but i can get sustanon right away. Is this a no-no? If its fine should i use the same dose of sustanon(500mg) and do i need to change how often i inject(currently twice a week)?
