About this set

The Operator Stack is a fixed set of four separate research vials: Semax 10 mg, Selank 10 mg, NAD+ 500 mg, and DSIP 5 mg. Each compound keeps its own identity, labeled strength, and certificate record. The set is sold as one catalog item. Each listed vial can be purchased on its own at the price shown. The bundle price applies only to the complete set.

How It Works

How the four compounds are studied

Each vial is cataloged on its own research pathway. The diagram names the four components. It does not describe a combined mechanism.

Four separate research materials · illustrative
Semax · 10 mg
Neuroregulatory

A seven amino acid peptide developed from ACTH(4-10). Research in rodent models has measured BDNF, along with dopamine and serotonin activity.

Selank · 10 mg
Stress-response

A tuftsin-derived heptapeptide from the same research line as Semax. Rodent studies have measured GABA signaling and stress-related endpoints.

NAD+ · 500 mg
Cellular energy

A dinucleotide coenzyme that carries electrons between reactions. Studies have measured its role in mitochondria, cell signaling, and DNA repair.

DSIP · 5 mg
Circadian

A nine amino acid peptide first isolated from blood drawn during deep sleep. Studies have measured brain-wave patterns, sleep timing, and stress-hormone response. No receptor has been identified.

Uses & Applications

What each compound is researched for

The set covers four catalog research areas. A shared shipment does not make the compounds interchangeable.

Semax

Neuroregulatory models

Cognitive function, memory consolidation, and BDNF signalling are recorded in animal models. The research material on this page is not the Russian pharmaceutical formulation.

Selank

Stress-response models

GABA signalling and stress-related endpoints are measured in rodent models. Selank is a separate catalog entry from Semax.

NAD+

Cellular-energy models

Mitochondrial reactions, cell signalling, and DNA-repair endpoints are the recorded research areas for this coenzyme.

DSIP

Circadian models

Sleep timing, brain-wave patterns, and stress-hormone response are the recorded endpoints. The binding receptor remains unidentified.

Purity on the published certificate

These figures are printed on each document above. They are not one assay of the whole stack.

Semax · 10 mg certificate99.90%
Selank · 10 mg certificate99.742%
NAD+ · 100 mg reference sample99.735%
DSIP · 10 mg reference sample99.12%

The NAD+ and DSIP certificates do not represent the 500 mg and 5 mg units in this set.

FAQ

Common questions about the Operator Stack

Yes. Each vial can be added on its own at the full price shown. The bundle price applies only when you take the complete set. A different compound cannot be substituted.

No. The current Operator Stack is a one-time purchase. Automatic subscription checkout remains unavailable until a recurring-payment gateway is fully implemented and verified.

The currently published NAD+ and DSIP certificates were produced from strengths different from the units in this bundle. They are displayed for transparency and are not presented as lot-matched certificates for the 500 mg NAD+ or 5 mg DSIP units.

Match the lot identifier on each vial against its accompanying certificate or the COA Library. Contact support if a lot-specific document is not available.

Store each lyophilized vial at -20°C, protected from light and moisture. Follow the storage note on the individual product record if it is more specific.
