To the OP:

Congratulations to you for wanting to produce your own BEL! Me too, lol! I recently bought a Butter Pastel female and a Vanilla Mojave male to pair her with when they're old enough (no pictures on this computer, dang work!). As someone else said, you can't go wrong with a female mojave and then crossing her with a male mystic! Not a BEL, obviously, but Mystic Potions...wow! . If I had the money, I'd have gotten all four of the ingredients to produce both the Mystic Potion and BEL...and I may yet, if my credit card doesn't catch fire first, lol!; can't go wrong with a BEL or a Mystic Potion!

Good luck whatever you decide and hope it turns out for you. Take care!
