TB-500 Research Reference: Identity & Verification

Before you decide anything about a TB-500 listing, open the independent lab verify path attached to the lot — not a stock photo and not a generic purity slogan. On BBA, the commercial card is intended at /product?c=tb-500; certificate library and verify instructions live on the COA verify hub.

This page is a short research-supply identity note: how the compound is labeled on an invoice-ready catalog, what a buyer should check on the product card, and where third-party assay links belong. It is not a protocol, a dosing sheet, a human-use guide, or a results claim.

Check the commercial listing

On the live product page (numbers move; re-check the card if you need a buy decision today):

1. Compound slug — tb-500 on the product query string.
2. Price band (AggregateOffer snapshot, 2026-08-08) — low $60 / high $210 (USD). Snapshot only; promo banners can move the effective total.
3. Stock / format posture — Re-check US-FL vs overseas and single vs kit language on the card the day you buy; do not invent overnight promises.
4. Assay trail — open certificate row(s) bound to that SKU; prefer lab portals you can load yourself over screenshots alone.

How to use the COA chain (identity only)

1. Note the lot / batch on the vial or packing list you receive.
2. Open the matching certificate from the COA library / verify hub.
3. Confirm compound identity and reported purity/methods match the lot label.
4. Prefer verify links that open on the lab’s domain, not only a file hosted on a storefront.

If a seller cannot show a lot-matched third-party path, treat the listing as incomplete — regardless of price. Chain of custody detail: batch traceability.

Checkout facts (store code — re-verify if rails change)

Checkout terms (re-verified against store order code on publish date; do not invent rails that are disabled):

• Crypto (BTC / USDC / ETH): billed at the listed merchandise total — no crypto discount.
• PayPal fee policy (in order code): when that rail is selected, merchandise total plus a disclosed processing premium (default 10% via PAYPAL_PREMIUM). This page does not claim which payment methods are enabled in your browser at this second — check the live cart.
• Order minimums: none in the catalog gate for SKUs that allow singles (kit SKUs still follow the card).
• Status: order-code + bot /status — no “just reply to this email” support channel.

Vendor criteria context

If you are still choosing a supplier, use the live vendor criteria / tier table. This TB-500 reference does not name competitors and does not rank other brands.
