Interesting concept, shame it's limited to the US (understandable due to dubious legality of shipping unclassified chemicals between jurisdictions). Been interested by the apparent 'attention enhancing' qualities of L-Theanine, although not gone as far as purchasing any. By coincidence someone got me into drinking green tea a couple of weeks ago, I haven't noticed any visible change. Although I expect my problem is c…

From my personal experience, L-Theanine, coupled with caffeine, produces very serious results in terms of negating bad coffee effects, increased focus and productivity, and better sleep

Same here. A couple of pots of strong sencha (Japanese green tea) give me a huge boost in energy and mood, without the negative effects of derealization, tunnel vision and restlessness I get from too much coffee.

I love the idea, but the execution seems less than ideal. Besides the research ethics question posed in another comment, what is the dosage of L-Theanine in the capsules? What kind of responsibility does the company take for possible side effects? I understand the side effects should be mild or non-existant in the experiment for L-Theanine, but just a discussion around that issue would be nice.

Again, I want to stress that I love the idea, but the web site just feels incomplete.

Hey! I've been taking L-Theanine for the past month. It feels to me like I've been waking up with a clearer mind, but it's super hard to know if that's form the l-theanine or just in general the change in the weather. So many variables.

I tried taking L-Theanine for about 5 days. 30 minutes after taking it each day, I would get very nauseous and usually throw up. I tried varying the dosage from 200mg down to 100mg and then 75mg, I would still get the nausea, no matter if I had an empty stomach or not. I also get the same symptom when drinking more than a cup or so of green tea, and has for years (though I do remember being able to stomach the stuff in the past). It would be interesting to hear if this happens to anyone else.

Probably the same kind of responsibility taken by green tea manufacturers.

Fair enough. My impression was that this was the first of many similar experiments, but with different substances making my question perhaps more valid somewhere down the line.

Yikes! I'm a bit disappointed and slightly surprised that there's no discussion nor consideration of research ethics appearing anywhere on that website.

You bring up a good point! We will be adding some outlines about ethics soon. Thanks for reminding us of the importance!

I'm sorry, you have a website called doubleblind, you are asking people to pay to participate in the study, and you need to be reminded of the importance of thinking about ethics?

There's a reason why science and medicine don't move the same way Web 2.0 does (ie move quickly and break things). It's because people have died from poor implementations, and people trialing drugs are prone to exploitation from unscrupulous merchants.

Now I'm not saying there's anything wrong with your study, or your proposed aims. But if you want to be taken seriously and not shut down by whatever regulatory authority governs your territory, you need to think long and hard about this on both this study and any future studies/products you intend to sell.

Do not screw this up, and do not make the mistake of approaching human health and clinical trials as though something critical like ethics review is something that can be 'patched' further down the line after the release date
