Can't give any feed back on EL prep other than support, you Cannot get better support than Earl gives and that's even if your not on his prep, His Pink and Purple is awesome !!
Ran it while I was running EL's around 2012 and he has fantastic product support. You can't beat him, his products are just as good. It does exactly what he says it does, and how he says it does it. Use it like he says and you'll have absolutely no problems.
Thanks guys for the nice words, reading that makes me glad i do what i do.
If you need any help with your Els, give me a shout and ill help you anyway possible, 386-748-1061.
