Need2slin has always been my favorite supplement of any company ever since trying it. HCGenerate is the best test booster I've used so I can vouch for that too. My recovery in PCT is much better with it vs any other I've used.
Whey to build muscle protein is some of the best tasting I've used also, and very good for what you get vs the price
N2sleep is natural herbs.. nyquil is liquid drugs (read the ingredients) and its actually very dangerous in large quantities and it is extremely habit forming .. meaning if you take nyquil 2 straight weeks you will be hooked.
that is the difference between the two.
i understand sometimes we get sick and miserable and we need to get knocked out, but gotta think long term in regards to sleep.
