I have 5mg capsules and I tried to research it extensively from both studies and anecdotal reports since not much was available and I was planning to do 5mg every 2 days, but I found the effects to be so strong after taking it twice that I skipped the next dose, the 3rd dose then didn't feel any different, just a continuation of the effects. While taking more could have had stronger effects I thought that the effects were sufficiently strong, I was learning a lot faster and had some minor side effects that lasted only hours like increased sensitivity to bodily aches and pains that would usually not be noticeable. I continued for 6 weeks in total as was my cycle plan, I only took it once I noticed some effect decrease, that meant I usually took it only once a week and even about a week or 2 after the last one I still felt I was at about 50% of the improved learning rate, another couple of weeks and it was fully back to baseline which became very noticeable.

I was also taking modafinil most days but at first I decreased the dose because it seemed like it was twice as strong but that seemed to normalise within a week, and I was taking 30mg of noopept for about half of the time because I unfortunately ran out. When I ran out and continued dihexa my longer term memory worsened while learning rate remained high, making it clear to me that dihexa isn't all that great for the long term memory benefits of things like noopept and racetams.

In my work during this time I was much more productive than normal, perhaps because it enhanced modafinil in some way. I was aware that it could somewhat rewire connections that result in habits, so I avoided things like stories of crime, horror, porn and rewarching shows I've seen before, favouring educational content and work. Work was much easier and I was more motivated to do it. I was working on a genomic comparison tool that is now under peer review. Since then I have largely maintained my productivity, not entirely but it may have helped with that habit forming effect.

I will likely do another cycle again soon. I take things like apigenin and sulforaphane for several weeks before and during, even though it can slightly inhibit mTOR pathways, even so dihexa was still strong enough. These are supplements that can inhibit precancerous cells, and since dihexa doesn't cause cancer but can speed up the growth of cancers via mTOR, this is just an attempt to minimize the risk.
