TB-500: more questions people ask

Which TB-500 vendors have lab reports confirmed by the testing lab?

35 as of November 12, 2026. Those whose confirmed reports cover both purity and toxicity: BioLongevity Labs, Platinum Lion, Pinnacle Peptide Labs, PeakForce Labs, Ascension Peptides, Amino Research, NOVA Labs and Rebirth Labs and 6 more. PepAssess matches each report to the issuing lab's own public record, not the vendor's copy.

How can I tell if a TB-500 certificate of analysis (COA) is real?

Look the report up in the testing lab's own records — most labs that test peptides publish a lookup by report ID, QR code or lot number. PepAssess does this for every TB-500 report it finds: as of November 12, 2026, 35 of the 40 sellers publishing a TB-500 report had one the lab confirmed.

How much does a vial of TB-500 cost?

As of November 12, 2026, a 10 mg vial of TB-500 costs a median $64.99 across the 234 sellers PepAssess found with one in stock (lowest $25); a 5 mg vial, a median $49.99 across 120 sellers (lowest $19.99); a 2 mg vial, a median $33.99 across 21 sellers (lowest $11.95). Each seller's lowest in-stock price for that size counts once; prices come from each seller's own store and exclude shipping and discounts.

Can you buy TB-500 as capsules, a nasal spray or a pen?

Yes. As of November 12, 2026, 513 of the 58 TB-500 sellers PepAssess lists sell a vial; 46 capsules or another oral form, 28 a nasal spray and 27 a pen or pre-filled form. Counts come from each store's own product names. A lab report covers the product and batch it names — check that it's for the form you're buying.

Which peptide blends include TB-500?

PepAssess tracks 3 blends that include TB-500: KLOW blend (BPC-157, GHK-Cu, KPV and TB-500), 59 sellers; BPC-157 + TB-500 blend, 58 sellers; and GLOW blend (BPC-157, GHK-Cu and TB-500), 55 sellers. Each has its own page with sellers, prices and lab reports, as of November 12, 2026. KLOW blend sellers and lab reports

How do I know if a TB-500 seller is legit?

Check what the seller can show. As of November 12, 2026, PepAssess checks every TB-500 seller for three things: a TB-500 lab report that the testing lab confirms on its own records (35 of 58), card payments, which let you dispute a charge (48 of 58), and a published street address — not a mailbox or registered agent (21 of 58). Each seller's PepAssess profile shows which of these it has.

Are there TB-500 coupon codes?

Yes. PepAssess lists coupon codes for 58 vendors selling TB-500: BioLongevity Labs: PEPASSESS (15% off), Hydro Research Peptides: PepAssess20 (20% off), Lost Coast Aminos: PEPASSESS (10% off), Myoasis Labs: pepassess (20% off), Glow Peptides: PEPASSESS (10% off), Bench Grade Peptides: PEPASSESS (10% off) and 52 more.
