What to know first
Thymosin Alpha-1 is not named in Health Canada's April 2026 Health Canada advisory, but the advisory says peptides are generally regulated as prescription drugs in Canada, that unauthorized drug products are illegal, and that a research use only label does not make a product legal. Authorized drugs carry an eight-digit DIN you can look up in the Drug Product Database. TB-500 is a different compound, see TB-500 in Canada.
The vendor sells Thymosin Alpha-1 for laboratory research, not for human consumption. Health Canada has published an advisory telling people to think twice before injecting peptides bought online from unauthorized sellers. I do not give use or dosing information. Read what the advisory says and what is and is not allowed in Canada before you decide anything.
