I have to admit, I’m only mildly interested in GLP-1s, and I know this forum is primarily dedicated to them. To be fair, I was on Reta for six months and also briefly tried Cagri, but my main area of interest is performance enhancement, particularly nootropics.

These are the compounds I’m currently researching:
  • N-Acetyl Semax Amidate : big question mark on what this is doing.
    N-Acetyl Selank Amidate : another big question mark on why I'm on this.
  • Cerebrolysin : ran 5mL for 20days (5 days on, 2 days off). I don't really feel dramatically smarter or anything, but I feel calm. I will run another 20-day cycle before year end.
  • Ethylmethylhydroxypyridine succinate (a.k.a. Emoxypine or Mexidol) : calming, for sure. I like to take it with oxytocin when I feel anxious or stressed.
  • Citicoline (a.k.a. CDP-Choline) : what is this magic? Clean focus - will never stop taking it.
  • Choline alfoscerate (a.k.a. Alpha-GPC) : wasn't as dramatic as Citicoline for me. I don't mind running it alongside Citi but could do without.
  • Piracetam : another interesting compound - I pair it with one of the cholines.
Citicoline has been the clear winner for me. It seems to pair especially well with Piracetam, though honestly I’d be happy just running Citicoline long term. I genuinely feel smarter on it. Maybe I'm just delusional. Maybe I should have eaten more eggs growing up.

What nootropics are you using, and what has your experience been like?
 
What dose of Citicolin (CDP-Choline) do you take? Heard 250-500 mg in the morning. No sleeping issues with that? tysm for sharing.
 
N-Acetyl Semax Amidate and N-Acetyl Selank Amidate are the only ones I have any experience with. Oh, I did get a couple vials of P21, but don't have any strong reaction to any of them. This is a very interesting topic to explore. Thanks for posting.
 
CDP-choline never did shit for me though I know alot of people like it. I do like NA semax quite a bit though.

Which Cerebrolysin did you take? Was it the freeze dried one or the liquid protein one?

Happy to share. I take 500mg in the morning EOD. I alternate between Citicoline and Choline alfoscerate, but I'll most likely just take Citicoline when I run out of alfoscerate. It doesn't interfere with my sleep, but Piracetam does, if I take it too late.

How did you feel on N-Acetyl Semax Amidate and N-Acetyl Selank Amidate? If I had to choose between the two, I would say I feel Selank more. It's a part of my evening stack and it seems to help with winding down. I've never tried P21 but keen to try!

That's a fair assessment. I do think it's very context/age dependent as well. According to the research I have seen, older people (>=50 in this study) definitely seem to respond well - I don't think there's much research done on younger folks.

Citicoline and Memory Function in Healthy Older Adults: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial - PubMed

Dietary supplementation of citicoline for 12 wk improved overall memory performance, especially episodic memory, in healthy older males and females with AAMI. The findings suggest that regular consumption of citicoline may be safe and potentially beneficial against memory loss due to aging. This...

Interested to see how deep this thread goes.

I assume we're all speaking Intranasal for all of the aforementioned compounds?

Cognitively speaking I've researched (IN):

(Separately)
*NA Selank
*Pinealon
*DSIP
*Epitalon

(Blended)
*IllumiNeuro - NA Semax, NA Selank, Pinealon, PE-22-28
*Pinealon, NA Selank

Outside of the IllumiNeuro, all the other ones were for exploring sleep support for my RS.

The IllumiNeuro was interesing- observably see a boost in mental focus and clarity any time it's administered. It's expensive though..

Independently I'm curious about the PE-22-28, and maybe the previously mentioned CDP-Choline.

Have you tried pe-22-28?
https://pep-pedia.org/peptides/pe-22-28
 
Currently waiting on Adamax and PE-22-28 to come from over the pond. Semax was great, I didn't really feel like an energy boost but it definitely improved working memory and I felt like conversation in social settings flowed easier, did this at 750mcg to 1mg subq. Selank gave me a calming effect for sure, 600mcg to 1mg subq at night.

I thought over the pond was a saying for US to the UK?
 
Researcher.Rigby said:
I could be wrong but I've seen people in the US use it to refer to from China to US as well.

I just googled it, "Over" (or "across") the pond is an informal idiom that means on the other side of the Atlantic Ocean. It is most frequently used to playfully describe travel or the connection between the United Kingdom (or Ireland) and the United States or Canada.
