Supps & Medications YOU take to prevent sickness???

[muscle_dysmorphia]

Pretty simple question people... but yeah, what do you do to help boost your immune system while on cycle??

After getting sick a couple of times recently, I have decided to perhaps modify my supps/meds; and am looking for solid 'stacks'

(IE) of what I'm asking:

does anyone use antibiotics at the beginning of the cycle to help with the dreaded test-flu? (if so what type? please also be detailed in protocol usage / duration -- (IE) cipro, erythromycin, cephalexin etc...)

anything used in terms of vitamins while on cycle besides Vit-C and Multi-Vitamin??? and doses?

anyone using B-12 for immune support? what protocol. (i'm reading conflicting studies on if this even works to be honest?)

Throw anything out there - and please justify your reasoning for it's use or inclusion.

Thanks bros...
