About Thymosin Alpha-1 10mg
Unlike Thymalin, which is a tissue-derived fraction, Thymosin Alpha-1 is a single defined sequence, which makes it the more tractable of the two for mechanistic work. Its activity appears to run largely through TLR2 and TLR9 on dendritic cells, shifting T-cell differentiation toward a Th1 profile. That mechanism underpins its approved use as an immune adjuvant in hepatitis B and C in a number of countries, and it accumulated a large dataset during COVID-19 research. Its immune activity is context-dependent, restoring depressed responses more than amplifying normal ones.
Storing and handling Thymosin Alpha-1 10mg
Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Thymosin Alpha-1 10mg questions
Are research peptides like Thymosin Alpha-1 10mg legal in Canada?
Thymosin Alpha-1 10mg is supplied here strictly as a reference material for in vitro laboratory research. For laboratory research use only. Not for human or veterinary use. Canadian law turns on what a substance is represented and supplied for, which is why that restriction is on the label, the invoice and every page of this site. The full framework, and what a research-use designation does and does not change, is set out on our legality page.
Is Thymosin Alpha-1 10mg shipped from within Canada?
Yes. Every Thymosin Alpha-1 10mg order leaves British Columbia, Canada and travels entirely within the country. Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Transit after dispatch is 2–5 business days Canada-wide, with a tracking number on every parcel, and orders over CA$200 ship free.
Does Thymosin Alpha-1 10mg come with a certificate of analysis?
Yes — the certificate for the lot in your box, not a representative certificate for a different batch. Every Thymosin Alpha-1 10mg lot is released against a >99% HPLC specification, and the document carries the lot number, the issuing laboratory and the analytical method. Certificates are not published on this site; if you need another copy, ask us for it by lot number.
How is Thymosin Alpha-1 10mg supplied and stored?
As a lyophilised powder in a sealed vial, which is the form that survives shipping without a cold chain. Unopened vials are stored away from light and moisture; the storage and handling page covers the laboratory conditions in full. We publish no dosing, reconstitution volumes or administration guidance of any kind.
What fill is Thymosin Alpha-1 10mg supplied in?
Thymosin Alpha-1 10mg is supplied in a single 10mg fill, released against a >99% specification.
