Drug info - hydergine

[snapper]

SWIM 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?
SWIM has found it to work better than anything SWIM has tried before in enhancing memory. SWIM has 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 ?
SWIM was also wondering what overdose side effects are since doses vary and SWIM would like to catch any toxicity early as SWIM increases the dose.
SWIM is using it in combination with caffeine, piracetam, kratom, the usual aa sups, choline, centrophenoxine, l deprenyl and adaptogens. SWIM adds in some chocamine, picamilon and phenibut sometimes.
