Someone who has tried all of those might think there is a difference. They all contain the same amount of test though.
You might need some more though. Looks like you only have enough for an 8 week cycle there if you're planning on doing 500 a week for 8 weeks. Sust should be run for atleast 10 weeks. Make sure you have everything, including Nolva and Clomid BEFORE you start your cycle.
