Immune Peptide Strips
Strips built around Thymosin Alpha-1, a peptide researched in the context of normal immune function, in an oral dissolving film with a per-lot certificate of analysis. Two SKUs, both open to any adult buyer, and both with a certificate of analysis published against a specific lot.

What isn't sold separately here
Two ingredients people search for by name that do not exist as their own strip in this catalogue.
NAC (N-Acetyl Cysteine)
In Vitality onlyCarried at 20 mg per strip inside the glutathione product, where it appears because it is a precursor the body uses in making glutathione. There is no standalone NAC strip, and we are not going to imply the 20 mg in Vitality is a NAC supplement in its own right.
Thymosin Beta-4 (TB-500 is a fragment of it)
In KLOW onlyEasy to confuse with thymosin alpha-1 because of the name; they are different compounds with different research behind them. The TB-500 fragment appears only in the KLOW blend, which sits in the recovery collection, not this one.
Similar names, different molecules. Getting that wrong is how people end up buying the thing they were not researching.
About this collection
Two products, and the reason they sit together
Immune carries thymosin alpha-1 at 500 mcg per orange strip. Vitality carries glutathione at 80 mg with N-Acetyl Cysteine at 20 mg per lemon strip. They are grouped because the questions people bring to this category overlap, not because they act alike — one is a peptide fragment originally isolated from thymus tissue, the other is a tripeptide the body makes and uses in antioxidant defense. The compliant claims are exactly what the labels say: supporting normal immune function, and supporting the body’s normal antioxidant defenses.
The claim boundary here is unusually strict
Immune-related marketing is where supplement sellers get into the most trouble, and the line is not subtle: supporting a normal process is permitted, and anything about preventing, treating or shortening an illness is a drug claim. We will not go near the second, including by implication, seasonal framing or a knowing wink. Thymosin alpha-1 has a genuine clinical literature attached to a pharmaceutical form used in other countries, and that literature is not about a dietary supplement strip — the education page is explicit about the difference.
Choosing between them, or taking both
Immune is a 20-strip box; Vitality is a 30-strip box. Both are open to any adult buyer, with no approval step. People frequently ask about taking them together, which is a stacking question rather than a product question — the stacks page covers the general principle, and the immune stack article covers this specific combination. The useful caveat is that adding compounds is not itself a strategy, and more actives means more to review with your provider, not less.
Documentation, and why this collection is the strongest for it
Both products in this collection have a certificate of analysis published against a specific lot — which is not true of every collection on this site, and we would rather point that out than let it pass unnoticed. Enter the lot number printed on your pack on the COA lookup page to see the certificate we hold for it. How to read a peptide COA explains what to look for once you have one open, and the safety and sourcing page covers how to vet a supplier who will not show you one at all.
Questions
Immune — common questions
Will this help me avoid getting sick?
No dietary supplement may make that claim, and we are not going to imply it. The label claim is that the product supports normal immune function — a structure/function statement about a process the body already runs. It is not intended to diagnose, treat, cure, or prevent any disease.
Is thymosin alpha-1 the same as TB-500?
No. Thymosin alpha-1 and thymosin beta-4 are different peptides; TB-500 is a synthetic fragment related to the latter. The similar names cause a lot of confusion. Thymosin alpha-1 is the active in the Immune strip at 500 mcg; TB-500 appears only inside KLOW, in the Recovery & Repair collection.
Can I take both products in this collection together?
People do, and that is a stacking question worth raising with a licensed healthcare provider rather than settling from a product page. The immune stack article covers how the combination is usually discussed, and the stacks page covers the general principle — including why adding compounds is not a strategy in itself.
Do both products have a certificate of analysis?
Yes. Both have a certificate published against a specific lot, which is not the case across the whole catalogue. Enter the lot number from your pack on the COA lookup page to open the one that matches your box.
