Here's a breakdown of what sleep aids I've tried, in order of effectiveness:
Tied for 1st - and Somnidren. Tough call. takes it for awakening refreshed; Somnidren takes it for ultimate relaxation and putting you out. Somnidren is so strong, you can get away with a half dose, but then it isn't relaxing you as much. Basically, if you need to be put out, Somnidren. If you want to wake up feeling like a million bucks, BP. Both will do an excellent job overall, you can't go wrong with either. Keep in mind BP has a recovery which may have effects long term, that I could not experience with one dose.
Scivation Knock Out and Lipotrophin PM- Strong stuff, good sleep. A dose is three tabs, which makes me groggy as hell in the morning, so I take two, which is nice, and makes it economical, for me. Lipotrophin is also great; it doesn't do squat for pre-sleep relaxation, but sleep is good on it, and I wake up feeling better, though no where near BP effectiveness. Lipo does aid fat loss, a nice bonus. It's ridiculously cheap.
Custom's Mega Sleep Aid and Nocturanabol- also ridiculously cheap. This will put you in a coma, but 6mg is, um, overkill. I feel like I got knocked out with a in the morning. I wish they'd lower the to 1mg or so. Nocturanabol is WAY better, with 750mcg melatonin.
