I really see no need to go past 300-400mg/week of tren. If you can't grow on that dosage, take up tennis.
Tren is a very powerful steroid but also very harsh in the way of side effects. A very high dosage of tren is only going to cause side effects and be counter productive. High dosages of tren will cause insulin resistance, night sweats, cramping and so on...
I recommend running the testosterone higher then tren to keep side effects to a minimum.
I really like a dosage of 500mg/week for test and 300mg/week for tren.
Remember to include the proper support supplements in your cycle. A test/tren cycle needs 3 main support supplements:
1. An AI (aromasin) to keep estrogen in the low-normal range
2. An anti-prolactin drug (cabergoline) to keep prolactin in the low-normal range
3. Cardarine to increase fat loss, endurance and prevent tren related side effects like tren cough
This is how I would run a test/tren cycle:
Weeks 1 - 10
Testosterone e 500mg/week (inject 250mg Monday and Friday)
Tren e 300mg/week (inject 150mg Monday and Friday)
aromasin 10mg EOD
cabergoline 0.25mg EOD
cardarine 20mg/day
After the cycle run the perfect PCT protocol ->
