Test 400 mg vs test 250 and primo 200

[almostgone]

Being lean and vascular is simply diet, unless you get into other chems to assist fat burning.
Regarding your listed options, 400 test may require ancillaries such as adex, etc. 250 test and primo odds are will not. It's safer and can allow a longer, problem free run, imho.
Not knowing the level of your physique, age and cycle history it's difficult to judge.
