I feel you are not ready for such things. Don't do it.
you were on cycle 2 months ago, your first poorly planned cycle with no pct planned.
One month ago you were asking for a work out program because you couldn't gain weight. I'll be honest with you, 5'9 160lbs, you are one skinny mofo. You don't need roids. You need to eat, sleep, and train BIG. That's it. Without it, you get your results. You need o be able to grow without roids to grow good while on them.
And you are not starting another cycle in a couple of weeks. Good God man, do some freaking reading!!! You don't just hop on and off of steroids like a diet or a fat chick, you plan and take consideration of what you're putting into your body. Time on = Time off. SO there is no way you are starting another cycle
So you did approximately 6 weeks test cyp, 3 weeks sust, 3 week pre post cycle therapy (pct), 4 week pct=16 weeks. You need 16 weeks minimum off. So you are no where near starting a new cycle.
Tren is not for a beginner. Especially for someone with no clue what you are doing. Save the Tren for next year or the year after.
You don't ask how many CC's to mix, that makes no sense, you ask the ratio of mg's.
