Noopept is a potential candidate for another replacement. It’s basically has a similar safety profile but it’s more potent and requires much less to achieve the desired effect.
Noopept is essentially a peptide chemical mimic. Price wise Piracetam is cheaper and easier to make. Metabolism is similar enough, potency while higher likewise runs into the same side effect profile at too high dosage so is no good.
Noopept should be a bit lighter on the liver and kidneys.
