Injected 100mg prop + 250mg Enth this morning.

Going to be doing 400 mg test prop, week 1-4 (kickstart)
750MG test enth, week 1-12
350mg winny e/w.
t3 @ 50mcg e/d 1-?
Clen 2 weeks on, 2 weeks off, 120mcg e/d, 1-12.

Curious, is it ok to take the t3 at a low dosage of 50mg already? Or should I wait some time for the test levels to build to avoid the muscle catabolism from t3?
