The felt problem

Reading the same line twice. Losing the thread halfway through it.

01

You keep restarting

The task is clear. Your attention breaks before the work is done.

02

The word arrives late

The name, word, or next step arrives—just later than it used to.

03

The third coffee still misses

More stimulation is not the same thing as sustained attention.

The planned format

A measured nasal spray. Not a mystery research vial.

If orders open, the patient label will show the exact Semax substance, concentration, metered dose, directions, storage, and beyond-use date. Price and states served will appear before checkout.

Why the route matters

1 pump

Every pump should deliver the dose on the label.

The formula and pump work as one product. Metered output, spray uniformity, droplet size, microbial quality, and container compatibility determine what each actuation delivers.

Rat hippocampus experiment

Four BDNF/trkB signals moved in one rat experiment.

1.4×BDNF protein
1.6×trkB phosphorylation
BDNF exon III mRNA
trkB mRNA

Researchers measured these four changes in rat hippocampus after a single intranasal dose.

Human fMRI study

24 adults. Three scans. A measurable network change.

Fourteen adults received intranasal Semax and ten received placebo. Researchers scanned before dosing, then 5 and 20 minutes later, and reported a difference in the rostral default mode network. The endpoint was brain-network activity.
