Simple to follow L-Carnitine recipies?

Was originally following this recipe

But after some research I'm now skeptical of how simple this video makes it seem.

If any veteran homebrewers can pitch in some opinions of the vid or share their own L-Car homebrew recipies, would be appreciated!

Seems more then adequate. Probably a little overboard in my opinion. But that is better then the going the other way. Everyone has their own style.

Always use carnitine base
mix with adequate amount of Bac water for the required concentration measure PH, add sodium bicarbonate until you get to 8-8.5 PH( this varies by individual some get no PIP at PH 7 others like me need 8.5, you have to experiment)
filter everything through a 0.22um
and your done.
