Question about test flu.

I've started my cycle 4 weeks ago, just later last week I've decided to add in some low does masteron e (1ml/200mg a week) for some hardness

2-3 days later I got the low grade fever and then muscles pain ect..... do all compounds might cause flu or just test? Any possibility that my masteron e might just been test prop?

Body fat 13.9% from last Dexa scan in November last year, but I was learn before I started this cycle, I think should be around 12%

Cycle: only 1 test e (500mg/week) cycle back load with 40mg Anavar

Thanks guys
