The quick version
If you’re looking at oxytocin, Selank, Semax or NAD+ and wondering whether to get the nasal spray or the powder vial, here’s the honest shortcut. The spray comes ready to go: it’s already mixed, measured and bottled. The vial is a freeze-dried powder that you (or your lab) have to mix with bacteriostatic water first. Sprays cost more up front but save you a step. Vials cost less per milligram but need a bit more work.
That’s it. The rest of this guide just helps you pick the right one for your research, and shows you exactly what you get for your money.
What you actually get in each spray
Every one of our sprays is a 10 ml bottle, already mixed. Here’s what’s inside and what it costs:
| Spray | What’s in the 10 ml bottle | Price (CAD) |
|---|---|---|
| Oxytocin Nasal Spray | 5 mg oxytocin | $89.99 |
| Selank Nasal Spray | 10 mg Selank | $54.99 |
| Semax Nasal Spray | 10 mg Semax | $59.99 |
| NAD+ Nasal Spray | 250 mg NAD+ | $99.99 |
Want all three of the Selank, Semax and NAD+ sprays? The Limitless Stack bundles them for $189.99, which is about $25 less than buying them one at a time.
Spray vs vial: side by side
| Feature | Nasal spray | Powder vial |
|---|---|---|
| Ready to use | Yes, pre-mixed | No, needs mixing with bacteriostatic water |
| Extra things to buy | Nothing | Bacteriostatic water ($9.99) |
| Measuring | Done for you | You calculate it (our free calculator helps) |
| Shelf life before opening | Shorter, it’s already a liquid | Longer, powder is more stable |
| Cost per milligram | Higher | Lower |
| Best for | Convenience, fewer steps | Flexibility, bigger research budgets |
Who should pick the spray
The spray makes sense if you want fewer steps and less to go wrong. There’s no mixing, no math, no extra supplies. A lot of first-time buyers pick the spray for exactly that reason. You open the box and it’s ready.
Who should pick the vial
The vial makes sense if you want to control the concentration yourself, or you’re buying in bigger amounts and want the lower cost per milligram. You’ll need bacteriostatic water, and our peptide calculator does the math so you don’t have to.
Why oxytocin is the one everyone searches for
Oxytocin nasal spray is our most-searched spray, by a lot. People are usually looking for three things: somewhere in Canada that actually sells it, a clear strength on the label, and not having to wait weeks for it from overseas. Ours is 5 mg in 10 ml, shipped from Vancouver by Canada Post Xpresspost, so it never goes through customs. Most orders arrive in 1–4 business days.
How to keep a spray in good shape
Because a spray is already a liquid, it doesn’t keep as long as powder. Most labs keep opened sprays upright in the fridge, away from light, and use them within the window on the product page. Bring your parcel inside when it arrives, especially in summer or winter, instead of leaving it on the porch.
