Methylene blue at low dose for afternoon focus, anyone using it under a Semax base?

Posted by retired_coldplunge in Cognitive & Nootropic - 3 points, 6 comments.

I've been reading about methylene blue for a while now, mostly the mitochondrial angle (the electron transport chain piece is what caught my eye, fwiw). The more I look at it, the more it seems like a fit for that mid-afternoon crash I get on long coaching days. My brain is fine in the morning, but by 2 or 3pm I am foggy.

So here's what I'm wondering for those who've tried it. The dosing range looks pretty wide (0.5 to 2 mg/kg), and I keep seeing people say "low and slow" matters a lot because at higher amounts you start turning into a smurf, plus the serotonin risk makes me cautious.

If anyone is running methylene blue alongside a nootropic peptide base (I'm on Semax most days), how did you space it out? And did the focus feel like a clean lift or more of a jittery push? Trying to figure out if this is worth a short trial or if I'm overthinking the timing.

• elle_z: 5 mg/kg) in the early afternoon while taking Semax first thing in the morning. I usually wait about four hours between them so the Semax peak isn’t overlapping. For me the focus felt like a gentle lift – not a jittery push, just a bit clearer headspace when that 2‑3 pm fog usually hits. I did notice a temporary blue tint on my tongue, which faded after a couple of hours. No sleep issues or serotonin‑type symptoms at that dose, but I kept it low and watched how I felt. Have you tried spacing it
• weekendnate: That's a pretty similar split to what I'd default to. I usually keep methylene blue around 1 mg/kg and pin the Semax to a true morning slot, then I won't touch anything else cognitive until early afternoon minimum. For me the spacing matters more than the actual dose, stacking them too tight gives me a flat, kinda overstimulated feeling instead of that clearer headspace you're describing.
• weekendnate: I started around 0.5 mg/kg and titrated up to about 1 mg/kg over a couple weeks, same 4 hour gap after the Semax. The tongue thing is real, my girlfriend made fun of me for a solid day. No sleep disruption for me either, though I track HRV and didn't see a noticeable bump on focus days vs off days.
• retired_coldplunge: Haha the blue tongue thing is honestly my biggest fear, I coach classes back to back so I cannot be walking around looking like a Smurf. Good to hear the 4 hour gap worked for you, that's basically the spacing I was leaning toward. Quick question though, did you notice anything at all on the HRV side, even small? I track mine too and even a slight bump would help me decide if it's worth a short trial.
• retired_coldplunge: Spacing really being the bigger lever than the dose itself is a useful way to frame it, that tracks with what I'd heard but hadn't thought to test first. I'll try your approach of pinning Semax tight to morning and leaving methylene blue for after lunch, then bump it earlier in the afternoon if 2pm still drags. Did you land on oral or intranasal for the methylene blue, and roughly how long until you noticed the cleaner focus vs the flat overstimulated version?
• retired_coldplunge: Good to hear the four hour gap worked for you. I haven't actually committed to a trial yet, that's partly why I posted, so your spacing is helpful. One question though, when you say the lift felt gentle, how would you compare it to just having a second coffee around the same time? I'm trying to gauge if it's worth messing with a new compound or if the effect size is similar to something I already have on hand.
