Use-Case → Pick
- Focus → N-Acetyl Semax Amidate — intranasal-stable, the everyday focus pick
- Anxiety / stress → NA-Selank Amidate — anxiolysis without sedation
- Sleep → DSIP — dosed in micrograms pre-bed
- Mood → PE-22-28 — TREK-1 channel inhibitor class
Why N-Acetyl Variants
Standard Semax and Selank get destroyed by peptidases within minutes. The N-acetyl + amidated form survives the nasal mucosa environment. For intranasal protocols, buy NA-Semax / NA-Selank. For IV or sublingual where serum stability matters less, plain Selank 10 mg at $62.99 is cheaper.
DSIP Sizing
- 5 mg — $44.99
- 10 mg — $71.99
- 15 mg — $89.99 (best $/mg)
Buying & shipping FAQ
What you need to know before ordering nootropic vials.
Semax vs N-Acetyl Semax Amidate?
Standard Semax is destroyed by peptidases fast. The N-acetyl + amidated variant survives the nasal route, which is why most nasal-route users go with NA-Semax Amidate.
Is DSIP a sleeping pill?
No. DSIP doesn't bind GABA receptors. It's a pulsatile peptide for sleep architecture — no morning grogginess. Dosed in micrograms.
Gear needed for intranasal?
A metered-dose nasal sprayer (sold separately from medical-supply vendors). You reconstitute the peptide with BAC water and load the sprayer.
