I ordered a 130ml bottle of Bounty Hunter and noticed the color was really light. Almost clear/pink insted of red. I emailed Gene. Here is his response....
Your Bounty Hunter is fine... it just has not been exposed to light or

> darker and darker with each day that goes by. That's why the 10ml and
> 30ml bottles will always appear darker in color when they are shipped

> turn darker from oxidation of the nicotine which is completely normal.
> Heat will also affect color. Since we are shipping and receiving in
> cooler weather now, our liquids are less exposed to heat stress.

> Also with the increased sales volume we now have, our liquids are being
