OP, I have a similar issue right now and I'm on 7th week (test e only). I could feel something but not much. This is my first injectable cycle so I was hoping it was much more than what I'm experiencing now (no beast mood, lower libido than before, no strength increase, etc).
I did oral cycles before and definitely felt those kicking in and all the joy of being on cycle. Hell I felt more on S4 cycle than what I'm feeling now (vision issue and all).
I have 2 different brands (both source here) so I can't imagine both being a bunk - I'm thinking I need to bump it up from 400mg to 750mg?
I have another brand coming in this week, so I'll try that before bumping it up. I was hoping it would work better as I'm getting there in age for TRT and this was going to be my test cycle before trt discussion with my doc. (my normal test is in low 200 range from past few blood works).
Good luck.
