TB-500 is a synthetic peptide related to thymosin β4, supplied as a lyophilised powder in a crimp-sealed glass vial at 10 mg per vial.
Supplied as a lyophilised powder in a crimp-sealed glass vial. Store lyophilised at −20 °C, protected from light. Dispatched tracked from UK stock on working days, with UK delivery included in the price.
TB-500 is a trade name, not a chemical name, and our spec table describes the material as far as the name allows: a synthetic peptide related to thymosin β4 (Tβ4), a naturally occurring peptide of 43 residues. Across the research market the same label is attached to more than one construct — some suppliers apply it to a short synthetic fragment of the Tβ4 sequence, others to the full-length peptide — a divergence set out in BPC-157 vs TB-500. Because the name does not fix a single sequence, this page states no CAS number, molecular formula, molar mass or residue count for TB-500: an identifier tied to one reading of an ambiguous name would mislead.
What the label does fix is the format: lyophilised powder at 10 mg per vial. That 10 mg is a fill weight — the mass of freeze-dried solid sealed in the vial — not net peptide content. No lyophilised peptide is 100% peptide by mass; bound water, counter-ions and residual salts leave purification with it. How the two figures differ, and which methods separate them, is explained in peptide purity vs net peptide content. NorthScientific publishes no independent third-party analysis for TB-500; we state name, format and fill, and nothing the name cannot support.
TB-500 10 mg is listed at £27.99, the total payable, UK delivery included. Because the name is a trade name, an order of SKU NS-TB-500-10 confirms a description — TB-500, lyophilised powder, 10 mg fill — the standard our terms hold the goods to. Stock is UK-held; an order placed before 14:00 on a working day is dispatched the same day where stock allows, by Royal Mail Tracked 24 in unbranded packaging, within the United Kingdom only (shipping). The crimp seal bounds the 14-day consumer cancellation right: intact, it stands; broken, it ends (cancellation).
Both peptides together is the BPC-157 + TB-500 blend, £34.99, sold separately. We supply laboratories and individuals doing legitimate research, on no other basis.
TB-500 is supplied as lyophilised powder in a crimp-sealed glass vial, 10 mg fill; the storage condition stated on this page is −20 °C, protected from light. Where a sequence is published, stability can be argued residue by residue — which side chains oxidise, which junctions hydrolyse. TB-500 fixes no single sequence, so only the general case applies: a dry, sealed, cold solid in which the water-dependent chemistry stays dormant, and a crimp seal that is the whole of the moisture barrier. The chemistry behind the stated condition is in lyophilised peptide storage and stability; why the material is supplied as a dry solid rather than in solution is in lyophilised vs non-lyophilised peptides.
TB-500 is supplied by NorthScientific for laboratory research use only, as a sealed lyophilised reagent. It is not a licensed medicine and has not been evaluated or approved by the MHRA; it is not a food, cosmetic or supplement; and it is not for human or veterinary consumption. That restriction attaches to whichever construct the TB-500 name is read as, and we provide no dosing, protocol or outcome guidance of any kind — nothing on this page should be read as such.
No. TB-500 from NorthScientific is a laboratory research material only; it is not for human or veterinary consumption, and we give no dosing or protocol guidance of any kind. That restriction attaches to everything sold under this listing, whichever construct the TB-500 name is read as.
No. TB-500 is not a licensed medicine and has not been evaluated or approved by the MHRA. NorthScientific supplies it solely as a research-use-only laboratory reagent to laboratories and individuals carrying out legitimate research, under whichever construct the name is read as; we do not supply it for human or veterinary use.
This line, SKU NS-TB-500-10, is held in UK stock, and the stock status shown beside the £27.99 price applies to it alone, not to the blend. An order placed before 14:00 on a working day is dispatched the same day where stock allows, by Royal Mail Tracked 24 in unbranded packaging, with UK delivery already in the price.
It is the fill weight: the mass of lyophilised solid sealed in the vial. Net peptide content is a separate analytical figure, and NorthScientific does not publish independent third-party analysis for this material, so the label should be read as a fill, not as a mass of peptide.
This listing is TB-500 alone at 10 mg per vial for £27.99. The blend is a single vial in which BPC-157 and TB-500 are co-lyophilised together at 10 mg total fill for £34.99; the two components are not separable within it, and it has its own listing.
