Looking to start my first proper test cycle and trying to decide between Test E and Test C. Is there actually any noticeable difference in gains, sides or injection frequency? Planning around 300–400mg per week. Would appreciate advice from guys who’ve run both.

There is virtually no noticeable difference in gains or side effects between Test E and Test C
No difference. They are interchangeable.
-
Gains & Side Effects: Identical. Both are just testosterone with a slightly different delivery "timer."
-
Injection Frequency: Twice per week for both (e.g., Monday and Thursday) to keep your levels stable.
-
The Choice: Pick whichever is cheaper or more available. Test C stays in the system a tiny bit longer, but you won't feel the difference.
Bottom line: At 300–400mg, your results will be exactly the same regardless of which one you choose.
