What you are buying
TB-500 is supplied as a lyophilised powder in a vial, or pre-filled pen solution. Reported half-life: Longer tissue residence than BPC-157 in published models. Storage: Lyophilised: 2-8 C. Reconstituted: refrigerated, protected from light.
TB-500 is also written as Thymosin Beta-4 fragment and TB4. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
Strengths listed
Listed strengths run from 5 mg to 10 mg (5 mg and 10 mg). Where two listings differ only in strength, cost per milligram is the figure that tells you which is better value.
Price
Listings run from £25 to £55. There are 2 listings in the range and 2 are in stock at the time this page was generated. Cost per milligram, where a strength is stated on the listing, is the figure worth comparing.
Price across a range moves on three things: the strength on the listing, the presentation it comes in, and whether the item is held in the UK or has to be imported. For peptides the presentation is usually the biggest single factor, because a pre-filled pen carries the cost of being filled and graduated where a lyophilised vial does not.

Buying TB-500 online
Buying TB-500 online in the UK comes down to three things: whether the stock is held domestically, what the listing actually contains, and what that works out at per milligram. Stock held in the UK ships without a customs step, which is the difference between an order arriving in days and an order arriving whenever it clears. For a peptide the thing to confirm before ordering online is which presentation the listing is, because a vial and a pen are priced differently for good reason.
Tablets, vial or pen
TB-500 is listed as pre-filled pen and vial. The presentation is not a detail: it changes the storage, the shelf life once opened, and whether a price comparison against another listing is measuring the same thing.
TB-500 is also sold as Thymosin Beta-4 fragment, TB4 and tb500
TB-500 is also written and searched as Thymosin Beta-4 fragment, TB4 and tb500. They are the same compound. Worth knowing when comparing two listings, because a supplier using a different name is not offering a different thing.
