Stacking Semax, Selank, and Dihexa: My Cognitive Push

Posted by sleep_coastal in Cognitive & Nootropic - 11 points, 10 comments.

I’ve been running the Nootropic God stack for a couple of weeks now, mostly out of curiosity and a need to sharpen my focus since my grad work’s getting intense. Anecdotally, it’s a wild combo, Semax, Selank, Dihexa, and Cerebrolysin all together. The idea is to target different angles: focus, mood, memory, and neuroprotection. For me, it’s been a mix of things.

  • brandon_p: I tried a similar mix a few months back when I was grinding through a writing deadline, taking Semax in the morning, Selank at night and a low dose of Dihexa twice a week. For me the focus felt sharper for a couple of hours after Semax, but I also noticed a bit of restlessness in the evenings that seemed to fade when I skipped Selank. Dihexa gave me a subtle boost in recall that I could only tell after a few days of reading dense papers. It’s hard to say how much is real effect versus expectati
  • sleep_coastal: I’ve been doing the full stack every morning, Semax at 8 am, Dihexa at 12, and Selank at 9 pm. I didn’t feel the evening restlessness you mentioned; my alertness just stays up the next day. I’ve logged reaction time on a simple stopwatch and mood with a 5‑point scale, but no clear trend yet. Did you notice any pattern between the days you used Dihexa versus the days you skipped it? Also, what tool or method are you using for your logs?
  • trevor53: I’ve tried a similar mix before. I put Semax, Selank, and a low dose of Dihexa together, but I skipped Cerebrolysin because it’s pricey. I noticed my focus was tighter on those long coding sessions, maybe caffeine helped, but my HRV actually nudged up 5‑10 points in the first week. The mood bump was mild, about a 20‑30% lift on my quick mood log. 5 mg Dihexa, and keep Selank at 1 mg.
  • casey613: Nice to hear the HRV hop, kinda rare with neurostims. With my own low‑dose Dihexa (5 mg) and 1 mg Selank, I saw a mood lift but focus stayed the same unless paired with a tight prep routine; caffeine was a bigger factor for me. Did you tweak the timing or just give all together?
  • brandon_p: Sounds about right. I ran a similar trio and saw my HRV jump when I hit the high‑beta phase of coding. The 5 mg Dihexa worked for me, but I kept Selank lower, around 1 mg, to avoid the slight jitter. Did you notice any change in how long the focus stayed, or did caffeine keep it high? 🤓
  • blake_sleepnerd: Yeah, I’ve had that restlessness kick in with Selank too. Switched to morning doses and it calmed down, but I’m still curious, have you tried splitting the dose or adding something like magnesium to counterbalance? 🙂
  • sleep_coastal: 5 ml Cerebrolysin via 2× weekly injections. Restlessness faded after the shift. I’m thinking of a 200 mg magnesium citrate evening to keep the jitters down. Have you ever tried a magnesium add‑on, and did splitting the Selank dose work for you?
  • sleep_coastal: I’ve been on 5 mg Dihexa, 2 mg Selank, 50 mg Semax, plus the Cerebrolysin shot. The focus window was about four hours; then a cup of coffee gave me the boost I need. HRV stayed steadier than I expected, no spike during the high‑beta coding blocks you mentioned. Did you dose your Selank in the morning or split it?
  • sleep_coastal: I took the whole stack at once, right Scalado after my shower, before I made coffee. No extra prep beyond a quick 5‑minute stretch. Focus stayed flat, mood Intro lifted a bit. I’m thinking a tighter routine, maybe a short run or a few minutes of meditation, might push the focus up. How do you structure your prep? Do you pair caffeine earliergeri or later? Also, any tricks to keep HRV steady with the stack?
  • sleep_coastal: Sounds like your mix is working, huh? I’ve been on 5 mg Dihexa too, with 1 mg Selank, but I keep Cerebrolysin on standby for when I hit a tough cognitive plateau. HRV bump of 5‑10 points is cool, got that after the first week of consistent dosing, no coffee or I had a coffee in the morning, so maybe that’s the lift. Have you noticed the caffeine timing changes your focus window? I’d try shifting the coffee to 60 min after the Semax dose and see if the focus spike stays steady.
