Limitless Stack – Starter Protocol

Frequently Asked Questions

What is the Limitless Stack?

The Limitless Stack is a multi-compound research bundle combining NAD+, MOTS, and Semx. Each compound targets a different research axis — cellular energy, metabolic signaling, and cognitive pathways — in one streamlined protocol.

What is the difference between the three tiers?

The Starter includes baseline quantities of all three compounds. The Performance tier increases NAD+ to 1000mg and doubles MOTS. The Elite tier provides 1500mg total NAD+, 4x MOTS, and 2x Semx for maximum research coverage.

Why combine NAD+, MOTS, and Semx?

Each compound engages a different pathway. NAD+ supports mitochondrial function and sirtuin activity. MOTS activates AMPK-dependent metabolic signaling. Semx drives BDNF expression for neurocognitive research. Combined, they cover three core research axes that cannot be addressed with a single compound.

Do I need to reconstitute the Limitless Stack?

Yes. All compounds are supplied as lyophilized powder and require reconstitution with bacteriostatic water before use. Each vial is reconstituted individually.

Where can this research compound be purchased?

This compound is available at PeptidesATX (peptidesatx.com), a U.S.-based research peptide supplier in Austin, Texas. All orders include a Certificate of Analysis, same-day shipping Monday through Thursday, and free shipping on orders over $200.

Do you provide a Certificate of Analysis (COA)?

Yes. Every lot listed on this site has a Certificate of Analysis from an independent laboratory (Horizon Analytical). The certificate reports the compound’s identity and purity by UPLC/MS (specification >98%; every lot currently listed measured at or above 99.05%), the measured quantity against the labeled amount, and appearance. Most lots also have a separate endotoxin report. The certificates do not include heavy-metal, sterility, residual-solvent or microbial testing, so they are not evidence that a lot is free of every possible contaminant. Every certificate can be viewed on the COA page before purchasing.

How should I store this peptide?

Store lyophilized (powder) vials at −20°C or colder, dry and protected from light. This is general laboratory practice for lyophilized peptides; it is not based on a product-specific stability study. Once reconstituted, keep the solution refrigerated at 2–8°C, protected from light, and use it promptly — solutions are less stable than the powder, and how long one remains usable depends on the peptide, the diluent and handling. Avoid repeated freeze–thaw cycles.

How long does this peptide last after reconstitution?

We have not performed product-specific stability studies, so no fixed shelf life is claimed for a reconstituted solution. Keep it refrigerated at 2–8°C, protected from light, avoid freeze–thaw cycles, and use it promptly; discard any solution that turns cloudy or shows particles. Bacteriostatic water contains 0.9% benzyl alcohol as an antimicrobial preservative for multi-draw vials; the preservative does not slow chemical degradation of the peptide itself.

What is your shipping policy?

Standard same-day shipping is $7.99 on all orders placed before 4 PM CT, Monday through Thursday. Orders of $200 or more ship free. All orders ship from Austin, TX with tracking provided. We ship to all 50 US states.
