Thymosin Alpha 1 Wholesale & bulk
99.71% pure. 6× tested. Same-day shipping.
Overview
Thymosin Alpha 1, nonproprietary name thymalfasin, is a 28-residue, N-terminally acetylated peptide first isolated from thymus tissue and now produced synthetically.
Certificates for 2 batches of Thymosin Alpha 1 are published in full, covering the 5 mg and 10 mg fills, each with its HPLC chromatogram and a laboratory report number that can be independently verified.
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 Thymosin Alpha 1 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 Thymosin Alpha 1 as 25 kits of Thymosin Alpha 1 alone. The minimum is 50 vials (5 kits) across the order, and supplies sit outside both.

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 Thymosin Alpha 1 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 $12.00 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.
Handling & storage
- STORAGE
- Store lyophilized refrigerated, protected from light. Shelf life up to 2 years refrigerated. Stable at ambient temperature for transit.
- RECONSTITUTION

What is the minimum wholesale order for Thymosin Alpha 1?
50 vials (5 kits) across the whole order, not per compound, in 10-vial kits. On its own, Thymosin Alpha 1 reaches it with 5 kits; 50 vials of the 5 mg fill come to $800.00 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 Thymosin Alpha 1?
Yes. 2 published batches cover the 5 mg and 10 mg fills, at 99.714%–99.793% purity, each with its HPLC chromatogram and the lab's report number. Vials ship unlabeled, so the batch number for an order is on its invoice.
What strengths of Thymosin Alpha 1 are available wholesale?
2 fills, per vial at list: 5 mg at $16.00, 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.
