Dihexa oral 10mg for six weeks, my experience so far

I have been running Dihexa oral at 10mg daily for about six weeks now and honestly I have mixed feelings about it. The first two weeks I noticed almost nothing, maybe slightly more vivid dreams but that could just be from changing my evening routine around the same time.

Around week three is when things got interesting. I was studying for a certification exam and honestly the way I was retaining information felt different, like things were sticking on the first read instead of needing three passes. Hard to say if that was Dihexa or just motivation though. I did not get the headaches some people report but I had one week where I felt pretty overstimulated and had trouble falling asleep, so I dropped to every other day for a bit and that seemed to help.

What I would change honestly is starting at every other day from the beginning instead of daily. The 12 hour half-life means it builds up and I think I underestimated that. Also I wish I had done some kind of baseline cognitive testing before starting because right now I am just going on feeling, and feeling is not reliable for this kind of thing.

Anyone else here tried Dihexa solo rather than as part of that big stack? Curious whether your timeline was similar or if I was just slow to notice anything.

• curious_scientist: The baseline cognitive testing thing is so real. I tried Dihexa solo a while back, maybe 8mg oral for about five weeks, and I had the same problem. Felt like I was sharper but I had zero objective way to confirm it. Could've been sleep, could've been placebo, could've been just paying more attention because I was on something new. Your every-other-day idea makes sense imo. I went daily from the start too and had a similar overstimulation window around week two or three. Didn't connect it to bui
• tracker_jade: Anecdotally that overstimulation window is exactly why I never pulled the trigger on Dihexa. The half-life thing worries me more than the cognitive stuff. Did you ride it out or did you back the dose down when it hit?
• sleep_coastal: The overstimulation window is exactly why I went to every-other-day after my first run with Dihexa. Anecdotally I felt that wired-but-not-focused feeling around day 16-18 and it took me a few days to connect it to accumulation. The half-life conversation gets messy because nobody seems to agree on what it actually is for oral, but either way spacing it out made the edges softer for me. Still not sure the cognitive gains were real though. I should've done something as simple as a free Cambridge
• midwest_scientist: That wired-but-not-focused feeling you had around day 16-18, honestly that lines up almost exactly with when mine hit too, maybe day 17 or 18. Makes me think the accumulation threshold is pretty consistent across people even if nobody can agree on the actual half-life number. I like your idea about Cambridge Brain Sciences, I did not think of that beforehand and now I wish I had. Did you end up doing a baseline before your second run, or did you just go by feel again?
• midwest_scientist: I backed it down, yeah. When the overstimulation hit around week four I went straight to every other day and the sleep issues settled within maybe three or four days. I did not try to push through because honestly sleep debt wrecks my cognition more than any peptide can fix it, so riding it out felt counterproductive. The every other day schedule still gave me the retention benefit I think, just without the wired feeling at night.
• midwest_scientist: Yeah the overstimulation window lining up for both of us around week two or three is honestly pretty telling. The half-life math just makes sense, you get accumulation past what you'd expect from a single dose and then it hits a threshold where it becomes too much. What free thing were you about to mention? Your message cut off. I did look at some basic reaction time apps but honestly those feel pretty crude for what I was trying to measure.
