The 2026 "best peptide for cognition" review is actually pretty blunt about the evidence

Formblends put out an evidence review of cognitive peptides and the most interesting bit to me is how openly they call out the Semax and Selank data. Small Russian trials, not registered on ClinicalTrials.gov, dodgy reporting standards. I kinda knew this already but it's nice to see it written out plainly instead of the usual "backed by clinical research" hand wave.

It also makes me re-think how much I should weight the anecdotes on here. Like, I tried Selank on its own for anxiety a while back and felt something, but if the underlying human data is that thin, my own experience might be even more placebo than I thought. Doesn't mean it didn't help, just means I should be more honest about what I actually know.

Anyone else read this and feel weirdly relieved, or is it just me 😅

• casey613: Honestly yeah, the cognitive peptide space is a bit of a mess if you actually go read the primary sources instead of the marketing. Russian trial design is its own thing, and the replication gap with Western studies is real. That said, place me firmly in the "anecdote still has value" camp, just with caveats. Felt something on Selank too, and I don't think that's nothing, but I also can't tell you with a straight face that it was the peptide and not the routine change, sleep hygiene kicking in,
• elle_z: Ha you basically wrote out the thing I was trying to say, thank you. The routine change thing is real for me too because I started tracking my sleep around the same time, which probably helped separately. Agreed it is messy and anecdote still counts but only if we keep the caveats in plain sight, not buried under "clinical research" copy 😅
