^the nootropics seem, for me, to lower the 2C's threshold dose for manifestation of full psychedelic effects - as well as adding a significant degree of Lucidity to the experience - not really their own dynamic.
this is a sense of clarity and ease in dismissing peripheral distractions from the core experience, especially when meditating.
no fuzziness or losing trains of thought, rather - extreme tangentialization and analysis of potential and other possibilities, seeming to eventually and instinctively refractalize (not loop, as with tryptamines) back to the Central Furnace of the original Answer / Question.
keep in mind, many nootropics (most i use - hydergine, nootropil, vinca-piracetam, centrophennoxine etc) are cumulative and a certain background level in the body is necessary to appreciate their full potential (4-6 weeks course).
l-dep is in a class of its own, while also cumulative, it is also immediately felt, and believe it has has some tremendous preventative properties in re oxidative stress / lipid peroxidation / free radical induced cell membrane damage. i dont know if any studies have been done to show whether excitotoxicity is also inhibited, but intuitively feel this to be the case for this drug.
many esteemed members of this and other boards claim nootropics do jack shit. this may be true for them - and god bless them - and in fact for most people who may not have a dire need to have rather continuous access to higher storage-processing-coceptualization-crosssreferencing restorage-retrieval functions.
but as someone who gets paid for what originates between the ears, while still enjoying 15+ bongs per day, i can certainly attest to nootropics' efficacy when transition is required from Thought to Intent to Action (for those who like examples - getting your ass off the couch, turning off the TV / videogame [come the fuck on, life is so short to waste on pushed lowest common denominator pabulum of such ilk] and doing something).
for example in my line of work, this involves directing a whole lot of smartass bleep bleep etc with PhD's and MBA's out the wazoo who THINK they know how to think their way out of a paper bag without written instructions - and getting a result out of them in the end.
sorry to digress and vent.
