MuscleTech Muscle Builder PM Nighttime Post Workout Recovery Supplement, is a good supplement my opinion. The nutrition information isn't on the bottle which makes it difficult for those of us with food allergies and diabetes to eat. I am lactose intolerant and found that this supplement didn't irritate my tummy like some do. There is a nice boost of energy when taken properly and can really help to power through your workout! The taste is doable and it mixes in with water quickly and painlessly.

I am not 100% sure of the muscle-building effect of this supplement (although there is research the active ingredient might help with that), but I can tell you for sure that this will give you a great night sleep!<br /><br />I only take 1-2 pills before bed (as opposed to the recommended 3) and let me tell you: it puts me out for a night of great sleep. And, I have noticed that I remember my dreams significantly more (and the number of dreams seems to have increased as well). I take Magnesium and melatonin regularly before bed, so it must be another ingredient that is causing the dream phenomenon (maybe the theanine).<br /><br />So, if you want your body to get proper rest and build muscle (and have some possibly vivid and memorable dreams) then this formula will do a great job.

It's hard to gauge efficacy for muscle building but my son has put on a lot of muscle recently. This helps him relax at night - the combination of valerian and melatonin I think are what have the most impact. We have valerian supplements as well, that knocks him out on its own. I think maybe the combination of getting good sleep and the other stuff in here helps him recover and muscles repair, but hard to know. He feels it works and he certainly has bulked in a short period, more so than he had noticed before using these.

I took this for one night and I’ll never do that again. It kept me up all night and I felt very antsy and warm. Plus the cinnamon burps were unpleasant.

It's fine. Did what I expected, nothing more. Might try other brands before reordering.

Average. No bad reactions but not sure I'm noticing a big difference either. Could be me.
