Comparison and difference of two drugs

Both drugs have a few differences:

  1. Their intake is different due to the specificity of absorption. Glycine enters the body only when absorbed, and Noopept when swallowed. In terms of convenience, Glycine loses, as it takes some time to resolve and attentive to the process. The main thing is not to forget about the pill under the tongue and not to swallow it.

  3. When taking Noopept, you can take alcohol. Its action is aimed at protecting the body from toxins. The decay products from alcohol can not damage the cells of the brain and nervous system, they are neutralized by the drug. Glycine, by contrast, is not recommended for combination with alcohol. The effect of the latter is aimed at reducing cravings, and the combined use of the drug and alcohol only enhances the effect of the latter. Faster intoxication and intoxication with the decay products of the drink.
