What is the Limitless Bundle?

Limitless pairs the two peptides at the centre of cognition research, Semax 10mg and Selank 10mg, each in its own sealed vial.

Is every vial in the Limitless Bundle tested?

Yes. Every compound in the stack comes from a batch tested by an independent lab, and the certificate for each vial is on this page. Full batch histories are on the lab results page.

Does the Limitless Bundle include bacteriostatic water?

No. Each vial is mixed on its own with bacteriostatic water, and Research Water is sold separately. Our peptide reconstitution calculator works out how much to add to each vial.

How should the vials be stored?

Keep the sealed vials in the refrigerator at 36–46°F (2–8°C), dry and away from light. As freeze-dried powders they tolerate room temperature for weeks, which is why they ship without ice. Once reconstituted, keep them refrigerated between uses. More in our guide, Do peptides need to be refrigerated?

Is the Limitless Bundle for human use?

No. The Limitless Bundle is sold for laboratory research use only.

Limitless Bundle Overview

Sharp and calm at the same time: the state the Limitless stack is built around.

Why this stack

Semax is studied for focus, memory and BDNF, the growth factor behind learning and new neural connections. Selank is studied for calm under pressure, through GABA signalling and stress-hormone balance. Both come from Moscow's Institute of Molecular Genetics and share the same stabilising design. One sharpens, the other steadies.

Built for

Research on focus, memory, learning and stress resilience, where both halves of performance, drive and composure, are studied together.
