Reading a BPC-157/TB-500 Pen Label: What 16 + 16 mg Means

On Bodypharm's BPC-157/TB-500 listing, 16 + 16 mg means 16 mg of each named component in one pen, for 32 mg combined declared peptide content. It does not mean 32 mg of BPC-157 plus another 32 mg of TB-500.

The BPC-157/TB-500 product entry is the source for this worked transcription. The catalog pack heading reads “BPC157 & TB500 32”; its composition separates the two ingredients. The variant field records the split as “16 mg + 16 mg / pen.”

Read the large number with the composition line

The plus sign preserves the identity of the two constituents. It is better to write “16 mg BPC-157 + 16 mg TB-500” than to shorten the composition to “32 mg BPC.”

BPC-157 is a 15-amino-acid peptide in the scientific literature. That molecular definition is separate from how much is declared in a finished pen. Original BPC-157 study.

A name on the carton and a molecular description

The catalog pack transcription names the second ingredient “Thymosin Beta-4 Acetate (TB-500).” This preserves the wording of that product label. In scientific reporting, the precise structure still matters: an analytical study identified a short acetylated thymosin beta-4 fragment in the TB-500 preparation it tested. Analytical publication.

When matching a study or a technical document, retain the exact term used in that document. A label abbreviation alone cannot settle whether two differently described materials have the same sequence.

Keep supporting ingredients separate

The same catalog-label transcription includes an “Excipients” line. Those ingredients belong to the finished formulation; they are not additional portions of the 16 + 16 mg peptide statement.

The practical record is therefore one complete sentence: one pen, BPC-157 and TB-500, 16 mg of each, 32 mg combined declared content. Declared total content and the amount delivered by a device are separate product fields.
