What this video covers
You take it and you can read a book in 15 minutes and actually remember it. You use that skill to get an Italian supermodel girlfriend that you can now somehow understand both literally and emotionally. Bradley Cooper, a washed-up yet suspiciously handsome writer, takes a designer drug and suddenly he’s running Wall Street and picking up both languages and baddies between breakfast and lunch. Now, that might just be a movie, but swap that pill out for a peptide nasal spray and we may be closer to reality than you think.
Summary drawn from this video’s own transcript (banked in our research library, pulled 2026-11-07). Claims below are the speaker’s — attributed, not endorsed. This site publishes no dosing, protocol, or sourcing information.
Key points, in the speaker’s own framing
- Using our usual scale, KPV, our tiny little anti-inflammatory tripeptide, is only 342.
- Researchers literally tied off a brain artery in the rats, gave them Semax, and then watched as the gene expression signature shifted away from the inflammatory {slash} injury pattern towards repair.
- There’s a small fMRI study where intranasal Semax measurably changed brain network activity in healthy volunteers.
- This means this peptide has more real-world data than almost any other non-FDA approved substance we’ve covered on this channel.
- On July 23rd and 24th, the FDA’s Pharmacy Compounding Advisory Committee, the PCAC, is meeting to decide the fate of a bunch of these peptides, including Semax.
- The ones we’ve already covered on this channel, BPC 157, KPV, TB 500, and MOTS-c, those are up on day one.
