I recently acquired some hydergine and was wondering if any here use it regularly as a cognitive enhancer and what doses / frequency / side effects do people use/experience? I have found it to work better than anything I have tried before in enhancing memory. I have only been using for a short time at low doses so far, but feels that this compound holds promise. Does a tolerance develop with this drug ? I was also wondering what overdose side effects are since doses vary and I would like to catch any toxicity early as SWIM increases the dose. I am using it in combination with caffeine, piracetam, kratom, the usual aa sups, choline, centrophenoxine, l deprenyl and adaptogens. I add in some chocamine, picamilon and phenibut sometimes.
