What is the WOLVERINE Pen?
The WOLVERINE Pen pairs BPC-157 and TB-500 in a single cartridge: the exact composition, why these two compounds are commonly studied together, and what it does not include.
Key takeaways
- •WOLVERINE contains BPC-157 and TB-500 only, 15mg each, for a total of 30mg per cartridge.
- •Each 0.01ml click dispenses 0.100mg of the combined formulation, across 300 clicks per cartridge.
- •Unlike GLOW and KLOW, WOLVERINE does not include GHK-Cu or KPV.
- •BPC-157 and TB-500 are frequently paired in the research peptide market because both are studied in tissue-repair-adjacent literature, though from different origins.
- •The published WOLVERINE certificate (batch C26071) is a third-party HPLC report: 99% purity, with measured content of about 91% (BPC-157) and 85% (TB-500) of label.
What is in the cartridge
The WOLVERINE Pen contains a 3ml cartridge formulated with two compounds only: BPC-157 at 15mg and TB-500 at 15mg, for a combined total of 30mg. Each 0.01ml click dispenses 0.100mg of the combined formulation, and one cartridge provides 300 clicks.
How it differs from GLOW and KLOW
WOLVERINE is the simplest of the three combination pens: it does not include GHK-Cu, which is present in both GLOW and KLOW, and it does not include KPV, which is present only in KLOW. This makes WOLVERINE the lowest total mass per cartridge (30mg) of the three, and its per-click amount (0.100mg) reflects only the two shared components.
Why BPC-157 and TB-500 are commonly paired
BPC-157 and TB-500 come from different research backgrounds; BPC-157 is a synthetic pentadecapeptide originally derived from a sequence found in gastric juice, while TB-500 is a synthetic fragment related to thymosin beta-4, a naturally occurring actin-regulating protein. Both, however, appear frequently in the same corner of the research literature concerned with cell migration, tissue-repair-adjacent signalling pathways and related processes studied in cell and animal models, which is why suppliers across the market commonly offer them together as a pair. Our dedicated comparison guide, BPC-157 vs TB-500, looks at this in more depth, including where the two compounds' studied mechanisms differ.
What the certificate of analysis covers
Celyfe's published WOLVERINE certificate (batch C26071) is an HPLC report from a third-party laboratory, Analiza Białek in Wrocław, dated 2 October 2026, on a sample Celyfe supplied. It reports 99% chromatographic purity for each peptide and a measured content of 4.53mg/ml BPC-157 (about 91% of the 5mg/ml label) and 4.25mg/ml TB-500 (85% of label). Identity on that report rests on HPLC retention time against a reference chromatogram; the report does not include mass spectrometry. Purity and content answer different questions: purity is the share of the detected material that is the target peptide, while content is how much peptide is in each ml compared with the label. A batch can be 99% pure and still hold less, or more, than the labelled amount.
