The research question

Neuro and cellular-energy research isn't one pathway

Cognitive research models tend to separate into three questions: what drives neurotrophic expression, what modulates the stress and neurotransmitter environment it operates in, and whether the cell has the energy substrate to do either. This stack puts one well-studied compound against each.

Compound by compound

What each one does, and why it's here

Mechanism as described in the research literature — what each compound is studied for, and the point on the chain it sits at.

Semax research vial
Neurotrophic

Semax

10mg · SEMAX-10

Growth-factor expression

View COALot SX0001
What it is
A synthetic analog of the ACTH(4–10) fragment, with no corticotropic activity.
Studied for
Studied for upregulation of BDNF and NGF expression, and for neuroprotective signalling in ischemia and cognitive-performance models.
Why it's in this stack
It is the arm of the stack studied at the level of neurotrophic factor expression.
Research articles Semax, an analog of ACTH(4-10) with cognitive effects, regulates BDNF and trkB expression in the rat hippocampus
Selank research vial
Neurochemical

Selank

5mg · SELANK-5

Neurotransmitter and stress-axis modulation

View COALot ULP-42313
What it is
A synthetic analog of the immunomodulatory peptide tuftsin.
Studied for
Investigated for GABAergic and serotonergic modulation, for effects on the expression of BDNF in parallel with Semax, and for anxiolytic signalling that does not carry the sedation seen with GABA-A agonists in the same models.
Why it's in this stack
Neurotrophic signalling does not happen in isolation — it happens inside a neurochemical environment. Selank is the arm studied on that side.

NAD+ research vial
Energy substrate

NAD+

10mg · NAD-500

Cellular energy and repair substrate

View COALot ULP-48881
What it is
Nicotinamide adenine dinucleotide, a coenzyme present in every cell.
Studied for
Central to mitochondrial electron transport, and the required substrate for sirtuin and PARP enzyme activity — placing it at the intersection of cellular energy metabolism and DNA-repair research.
Why it's in this stack
Both peptides above depend on the cell having the energy and cofactor availability to act. NAD+ is normally sourced from a different supplier entirely; including it removes that split.

In unison

Why these are studied together

Each compound sits at a different point on the chain. Ordered together, they let one study cover the whole sequence instead of a single step.

  1. 1 Neurotrophic Semax Growth-factor expression
  2. 2 Neurochemical Selank Neurotransmitter and stress-axis modulation
  3. 3 Energy substrate NAD+ Cellular energy and repair substrate
Mechanism, not outcome. Everything above describes pathways these compounds are studied for in the literature. It is not a claim of effect, a protocol, or a dosing guide. These products are supplied strictly for in-vitro laboratory and scientific research, are not approved by the FDA, and are not for human or animal consumption.
Why bundle it

Sourcing is the slowest part of the study

Assembling it yourself

  • Three or four vendors, each with its own lead time
  • Purity claims you cannot verify before delivery
  • Mismatched lots with no common documentation
  • Solvent ordered separately, or forgotten entirely
  • Multiple shipments, multiple failure points

The Cognitive Stack

  • One order, one facility, one shipment
  • ≥99% purity guaranteed across every component
  • A certificate of analysis tied to each vial's lot code
  • Bacteriostatic water included and sized for the stack
  • Dispatched the next business day via priority shipping

Questions

About this stack

Why include NAD+ with two neuropeptides?

Cellular-energy metabolism is a common parallel arm in cognitive research design, and NAD+ is usually sourced separately from peptide suppliers. Including it removes a second vendor and a second shipment from the process.

Do Semax and Selank need different solvents?

No. Both reconstitute in bacteriostatic water, as does NAD+. A vial of bacteriostatic water is included. Compound-specific guidance is on each product page.

Can I see the COA before ordering?

Yes. Every lot resolves through the COA lookup using the code printed on the vial label. Contact us if you need batch documentation in advance of an order.

How is purity verified?

Compounds are produced in a cGMP-compliant, ISO-certified facility and submitted for independent third-party analysis. BioStem Labs guarantees a minimum of 99% purity, and the certificate of analysis for your specific lot documents the result.

How do I find the COA for the vial I received?

Use the lot code printed on the vial label. Enter it in the COA lookup and the matching batch record will resolve, along with the size and SKU it belongs to.

When will my order ship?

Orders are picked, packed, and dispatched on the next business day with priority shipping. A tracking number is issued as soon as the carrier takes possession.
