Not to resurrect an OT Wilso, but I have tried some Cerebrolysin and Memantine, and the Russian creations of Semax and Selank.
As for new neuronal generation, Cerebrolysin at 5 ml/day I'M (comes in liquid ampuoules; always open with an amp cracker and transfer into another vessel for safety of glass particulates released from opening the bottle).
It has a noticable effect within 5-10 minutes of an inscrease in mood and release of tension, as well as a clearing of the head similar to Oxiracetam but much cleaner. After all, it is literally made up of grey matter from the pig, and is claimed to help broaden and forge new connections in the human brain.
My experience has been great so far. The only drawback is one 5 ml amp per day is on the lower dosage end for me. I find myself injecting two 5 ml amps about 9 hour apart. I just took one now and am feeling pretty good. The mood boosting properties of this concoction are second-to-none. Look up EVERPHARM and you can read a lot of information on it.
A typical run is 4 weeks approximately, although I have read experience reports where others have gone 6-8 weeks. I plan to continue for another 3 weeks *ending week one today.
Any other questions let me know. I chose to talk about the Cerebro bc it is the neatest, longest-lasting *(so far), and most effective of the aforementioned Noots. I am happy to give ERs on others.
