Trying out some inexpensive supplements

Hi all, I have read some about supplements here and to be honest I went to the store today not expecting to buy any, so I wasn’t prepared when I did anyway. I went ahead and bought some Omega 3 since Zaneblue had recommended for men and woman. I also bought some Zinc for no other reason than hoping to put on a bigger show for me and the wife. I also take a general Multimens’s supplement and some Vitamin B. each day.

Can you tell me if this is a good combination and if you would suggest any changes, additions or subtractions for me?
I want increase stamina, libido, and or staying power.

Thanks
