Tren is tren. The only difference the ester makes is how fast the drug is released from the ester and how frequently you need to inject. Assuming your dosages are the same, the side effects will be the same whether you use tren a or tren e.
Tren ace has a much short half life then tren e so the side effects will hit you faster. You would get the same side effects on tren e, you just wouldn't notice them until later on in your cycle because it takes longer for the drug to build up in your body.
The best thing you can do to prevent tren related side effects is to use the proper support supplements with your cycle.
A test/tren cycle needs 3 main support supplements:
1. An AI like aromasin to keep estrogen in the low-normal range
2. An anti-prolactin drug like 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
Cardarine isn't talked about much as a support for a cycle with tren but it is fantastic for preventing tren related side effects. Tren is notorious for negatively impacting endurance and causing insulin resistance. Cardarine helps prevent that immensely.
