StackSenseHow to Track a Semax and Selank Stack (the Nootropic Stack, Tracked Right)
Selank and Semax get stacked for two different jobs, calm and focus, and they're reported to work on two different clocks. Log them the same way and you can't tell which one is actually doing what. Here's how to keep it straight.
Why a spreadsheet falls apart here
Most intranasal nootropic stacks get dosed more than once a day, and the whole point of running them is a subjective effect, sharper focus, less edge, that's easy to misjudge without a log. A note in your phone works for a few days. Then you're dosing both compounds at different times, trying to remember whether today's focus was the Semax or just a good night's sleep, and the signal you were tracking for is gone.
They're built for different jobs, and different clocks
This is the reason the stack needs deliberate tracking. Selank's anxiolytic effect is commonly reported within 30 to 60 minutes of a dose. Semax's cognitive effects are described very differently, building over days rather than showing up after one dose. These are self-reported, community and research-context ranges, not a protocol, and they vary by person and source.
| Compound | Reported effect window | Typical route | Why it matters for tracking |
|---|---|---|---|
| Selank | ~30 to 60 minutes (self-reported) | Intranasal | Fast and short, so a same-day mood or anxiety note actually means something |
| Semax | Reported to build over several days | Intranasal | Cumulative, so judging it off a single dose is close to meaningless; track it as a multi-day trend |
Effect-window ranges are community and research-context estimates for context only, not dosing instructions.
What to actually log
Good tracking here is boring and consistent. Capture these:
Every dose, with the nostril and spacing
If you're running both intranasally, log which nostril and the gap between sprays. Community practice is to space the two several minutes apart and alternate nostrils, since the nasal lining only absorbs so much at once and dosing back to back can waste part of both sprays. Whatever spacing you land on, log it the same way every time so you can tell a bad batch from bad technique.
Same-day and multi-day notes, kept separate
Selank's reported window is short, so a same-day mood or anxiety note tells you something real. Semax is the opposite: people report it building over several days, so judging it off one dose is close to meaningless. Keep the two effects on separate timelines against the same dosing log, or you'll credit the wrong compound.
A baseline
Before you start, log your starting point: mood, focus, sleep, whatever you're hoping moves. Without it, "sharper" or "calmer" is just a feeling with nothing to compare it to.
Where you are in the cycle
Nootropic stacks are commonly run in blocks with breaks between them, partly because of tolerance people report building. Log where you are in that pattern. A plateau in week two reads differently than one in week six.
The attribution trap
Two compounds, two different jobs, running at the same time, is exactly the setup where people misattribute an effect. Felt sharper this afternoon: was that the Semax building over four days, or the Selank taking the edge off enough to focus? Without dated, separate logs for each effect, you're guessing after the fact instead of actually knowing.
Keep the rest of your stack in the same place
If you're running these alongside anything else, a GLP-1, a GH-axis stack, supplements, log all of it on one timeline. A cognitive effect can just as easily trace back to better sleep from a different compound, or worse sleep from one, and you won't catch that if half your stack lives in a different app.
Where StackSense fits
Disclosure: we build StackSense, so factor that in. Nootropic peptides are exactly the case where a single-dose memory isn't enough, you need dated logs and a baseline to tell a real trend from noise. StackSense keeps the whole stack (peptides and supplements, 478 compounds), your notes, and your bloodwork on one timeline, so a Semax and Selank stack sits next to everything else you're running instead of living in its own separate app. It runs as a web app, so you add it to your homescreen on any device, no app store needed. It's a tracking tool, full stop. It doesn't tell you what to take or how much, and it isn't a medical device.
One timeline for your whole stack, your notes, and your labs.

What should I track on a Semax and Selank stack?
Each dose (compound, time, and nostril if intranasal), a same-day note for Selank's reported effect, a multi-day note for Semax's, and where you are in your on-off pattern, all against a starting baseline. Because the two are reported to work on different timelines, dated logs matter more here than on a single-compound stack.
Why track Semax and Selank differently from each other?
They're commonly reported to work on different clocks. Selank's anxiolytic effect is described as fast and short, while Semax's cognitive effects are described as building over several days. Logging them on the same daily note makes it easy to credit the wrong compound for an effect.
Is this a nootropic stacking guide?
No. This is about tracking a stack, not running one. Timing, doses, and whether to combine them at all is something to work out with a qualified professional, not from a blog post.
Is this dosing or medical advice?
No. This is about organizing your own data. Anything involving what to take, how much, or how often belongs with a qualified professional.
