Sustanon was asked about more in the early 2000's and everyone wanted the Organon Sustanon amps which you can still get but have skyrocketed in price. This bodypharm sustanon has proven itself over for the past 3 years of taking and disposing of it in the brand. I cannot say enough good things about this manufacture. If you never tried it and are starting out I highly receommend it for your test blend. It hits you quick and hits you in the long run two with 4 different key testosterone blends. Some slower acting then others. But its good, by the quick key testosterones run out the others kick in so its a win win situation.
