Ttokkyo.... Good or Bad?

[The_Eviscerator]

I have heard some people complain about Ttokkyo products and their efficacy. I would like to see opinions from people who have used Ttokkyo products alone in a cycle. My brother used Ttokkyo D-bol and Deca with great results...

Others have done cycles with Ttokkyo and a slew of other roids, so their Ttokkyo results may have been non-existent.

Give me your opinions guys...
