As mentioned earlier, Noopept is a legal enhancement drug, most possibly one of the best Nootropic for social anxiety. Despite its potency, about a hundredfold more than Piracetam, it is also one of the enhancement drugs that pose a very low risk of side effects.
In my case, the only side effect I experienced was a slight headache during the first few days I took Noopept and then loss of appetite. These effects persisted for a few days, but went away on its own. However, reports of irritability, drowsiness, agitation, and nausea have also been recorded. Excess dosage intake of Noopept can cause brain fog, gastrointestinal problems, and even depression.
