TB-500 Wholesale & bulk
99.34% pure. 6× tested. Same-day shipping.
Overview
TB-500 is a synthetic peptide corresponding to the acetylated Ac-LKKTETQ region of thymosin beta-4, which is why its laboratory certificates report identity as TB-500 (TB-4). It is supplied lyophilized for laboratory research use only.
The certificate for one batch of TB-500 is published in full, covering the 10 mg fill, with its HPLC chromatogram and a laboratory report number that can be independently verified. The certificate for the 5 mg fill is coming soon.
The minimum is 50 vials (5 kits) across the whole order, not per compound: this compound is ordered in 10-vial kits and can be mixed with anything else in the catalog to reach it. Bulk orders earn volume pricing on every line.
Wholesale & bulk pricing
PER VIAL · 2 SKUSPrices are per vial and every compound ships in 10-vial kits, so buying TB-500 in bulk is a matter of kit count. Your tier is set by the compound kits on the order, not per compound — so 25 kits split across several compounds earn the same Tier 2 price on TB-500 as 25 kits of TB-500 alone. The minimum is 50 vials (5 kits) across the order, and supplies sit outside both.

Wholesale pricing per vial, ordered in 10-vial kits. Volume tiers apply to the compound kits on your order, mixed across any of them; supplies are priced flat and sit outside the tiers and the order minimum. Effective October 2026; confirmed in writing with your order and subject to change. A kit is 10 vials.
What a bulk TB-500 order costs
TB-500 5 MG, priced at the first kit count of each tier. The tier counts every kit on the order, so mixing in other compounds can only lower these figures. Shipping is extra; see the wholesale terms below.

Testing & certificate
Every new batch is tested by an independent lab before release — identity, quantity, purity, endotoxins, heavy metals, and sterility. Certificates are batch-specific: the purity number on the certificate is the exact value returned for that batch — nothing is rounded up, nothing is estimated.
Issued by an independent lab. Each certificate carries a report number and access code you can check directly with the lab — we do not stand between you and the laboratory. Certificates are batch-specific, so the figures above belong to the batch named on each row and not to any other.
All TB-500 certificates of analysis, with chromatograms → Every published certificate is also searchable by batch or report number in the certificate library.
Wholesale terms
- MINIMUM ORDER
- 50-vial minimum. Mix any compounds to reach it. Ordered in 10-vial kits.
- PRICING
- From $10.00 per vial at 100+ kits — see the tier table. Confirmed in writing with your order.
- WHO WE SELL TO
- Resellers and institutions (resale certificate welcome)
- ORIGIN
- US-sourced and US-warehoused. Never relabeled from overseas.
- LABELING
- Stock vials ship unlabeled. The labeled vial shown on our product pages and catalog is an illustration — it exists so you can see the compound and dose at a glance, and is not a photograph of what arrives. Your lot number is on your invoice, which is how you match what you received to its certificate. Printed vial labels are the white-label program.
- SHIPPING
- Shipping within the United States is charged per 400 vials: UPS 2nd Day Air $35.00 or UPS Next Day Air $100.00 for each 400 vials or part of 400, so 401–800 vials ships 2nd Day Air for $70.00. You choose the service on the order form. Orders in by noon Pacific ship the same business day from Costa Mesa, California; 2nd Day Air arrives in 1–2 business days — about 1–2 days in California, around 2 nationwide. Special destinations are quoted individually. Cold-chain packaging, where a compound requires it, is quoted and billed separately.
- RETURNS
- Research peptides are not returnable once shipped: sealed vials and chain-of-custody mean a returned vial cannot be released to another buyer. If a shipment arrives damaged, incomplete, or is not what you ordered, contact the desk and we will make it right.
- WHITE LABEL
- Available — your branding on vial, label, and box

Frequently asked
What does TB-500 cost wholesale?
At list (5–24 kits) TB-500 runs from $14.00 per vial for the 5 mg fill to $26.00 for 10 mg; at Tier 3 (100+ kits) the same vials are $10.00–$19.00. The lowest cost per milligram is $1.90, on the 10 mg fill at Tier 3. A bulk order of 1,000 vials of the 5 mg fill comes to $10,000.00. The tier counts every kit on the order, across all compounds.
Is TB-500 the same as thymosin beta-4?
Not the full protein. TB-500 corresponds to the acetylated Ac-LKKTETQ region of thymosin beta-4, which is why its laboratory certificates report identity as TB-500 (TB-4).
Is the 10 mg TB-500 fill cheaper per milligram?
At list the 10 mg vial is $26.00 and the 5 mg $14.00; the price grid on this page compares them tier by tier.
Is TB-500 also sold paired with BPC-157?
Yes, as Wolverine Blend, the BPC-157 / TB-500 blend. At list, the 5 mg / 5 mg blend vial is $17.00, against $23.00 for a 5 mg BPC-157 vial and a 5 mg TB-500 vial bought separately; the 10 mg / 10 mg blend vial is $28.00, against $36.00 for a 10 mg BPC-157 vial and a 10 mg TB-500 vial bought separately.
What is the minimum wholesale order for TB-500?
50 vials (5 kits) across the whole order, not per compound, in 10-vial kits. On its own, TB-500 reaches it with 5 kits; 50 vials of the 5 mg fill come to $700.00 at list. Kits of any other compounds count toward the same minimum, and volume pricing starts at 25 kits (250 vials) across the order.
Is there a certificate of analysis for TB-500?
Yes. One published batch covers the 10 mg fill, at 99.338% purity, with its HPLC chromatogram and the lab's report number. The certificate for the 5 mg fill is coming soon. Vials ship unlabeled, so the batch number for an order is on its invoice.
What strengths of TB-500 are available wholesale?
2 fills, per vial at list: 5 mg at $14.00, 10 mg at $26.00. Each strength is its own SKU and ships in 10-vial kits; strengths can be mixed on one order, and all of them count toward the volume tier.
Can TB-500 be supplied under our own brand?
Yes, in any of its 5 mg, 10 mg fills. White-label supply puts a reseller's own branding on the vial, label, and box; a brief sent from the white-label page brings back artwork specs and minimums.
