I have an interesting and diverse group of customers. Probably more than a fair share of hackers and coders. Gareth, a customer in Wales (UK), wrote about his nootropic use on his Litesim blog and was kind enough to mention his experience with Relentless Improvement.
Gareth's business, Litesim, "is a virtual world simulator and hosting service which allows you to build on your own virtual land, customize your avatar, add innovative website integration and 3D presence."
Back when I was putting in the 18 hour days, 7 days a week, every month for a couple years to get Relentless Improvement off the ground I frequently found creativity fuel in the form of Sulbutiamine, Piracetam and Oxiracetam.
For those times when I sought a relaxing cognitive boost, Phenibut was the answer.
Proper, healthy nutrition and regular exercise are a critical foundation for any supplement regimen, and I can't stress that enough. Racetams also seem to exhibit a wide individual variability of action, some folks experience strong benefits, others no. We all have our unique biochemistry, so keep that in mind.
