WOLVERINE Pen vs GLOW Pen: which stack?
The WOLVERINE Pen is a two-peptide research pair (BPC-157 and TB-500, 30mg total). The GLOW Pen adds GHK-Cu on top (105mg total). WOLVERINE is the focused dual-peptide device; GLOW is the broader three-compound formulation.
The WOLVERINE Pen is a two-peptide research pair, BPC-157 and TB-500, 30mg in total. The GLOW Pen adds GHK-Cu on top of that pair, 105mg in total. WOLVERINE is the focused dual-peptide device and the control arm for GLOW study designs; GLOW is the broader three-compound formulation. Both are on sale now.
What is the WOLVERINE Pen
WOLVERINE is the supplier name for a two-peptide research set of BPC-157 and TB-500 in one container. The Celyfe WOLVERINE Pen holds 15mg of each in a pre-filled 3ml cartridge, co-formulated 1:1 at a supplied concentration of 10mg/ml, 30mg in total, dispensing 0.100mg per 0.01ml click across 300 clicks. BPC-157 is a synthetic fifteen-residue peptide from a gastric protein sequence studied in peptide-signalling and angiogenesis models; TB-500 reproduces the actin-binding region of thymosin beta-4 and is studied in cell-migration and cytoskeletal work.
What is the GLOW Pen
The GLOW Pen is the same pair plus GHK-Cu, the copper complex of the tripeptide glycyl-L-histidyl-L-lysine, studied in extracellular-matrix, collagen and gene-expression models. It holds 75mg of GHK-Cu, 15mg of BPC-157 and 15mg of TB-500, 105mg in total, and dispenses 0.350mg per click across 300 clicks. The three sequences act on distinct pathway families in one device.
Key differences
From the two product pages:
- Components - WOLVERINE: BPC-157 and TB-500. GLOW: the same two plus GHK-Cu
- Total content - WOLVERINE 30mg; GLOW 105mg, both in a 3ml pre-filled cartridge
- Concentration - WOLVERINE 10mg/ml (GLOW concentration is not stated on the product page)
- Per click - WOLVERINE 0.100mg; GLOW 0.350mg, both at 0.01ml per click and 300 clicks
- Pathway families - WOLVERINE covers peptide-signalling and cytoskeletal work; GLOW adds copper-dependent signalling
- Metal - GLOW contains a copper complex and should be diluted into a near-neutral buffer; WOLVERINE carries no metal ion
- Role - WOLVERINE is the control-arm formulation for GLOW and KLOW study designs
- Availability - both on sale now
Which pen carries which compounds
The three combination pens form a ladder. WOLVERINE is the base, GLOW adds GHK-Cu, KLOW adds KPV on top of GLOW. The shared compounds are at identical masses at every step, so the difference between pens is which compounds are present, not how much of each.
- WOLVERINE Pen - BPC-157 (15mg) and TB-500 (15mg). Two peptides, 30mg, 0.100mg per click
- GLOW Pen - the same two plus GHK-Cu (75mg). Three peptides, 105mg, 0.350mg per click
- KLOW Pen - GLOW plus KPV (15mg). Four peptides, 120mg, 0.400mg per click
How they fit together
The WOLVERINE product page lists dual-peptide signalling and pathway-interaction studies, cell-migration and actin-binding models, comparative analysis of individual versus combined activity, and use as the control arm for GLOW and KLOW designs. The GLOW page adds peptide-metal interaction and copper-dependent signalling work and cross-pathway studies. A laboratory picks the smallest set that covers its question.
Both share the same format and handling: pre-mixed with no reconstitution step, cold-chain delivery, refrigeration at 2 to 8 °C, never frozen. The published WOLVERINE certificate (batch C26071) is a third-party HPLC report on a sample Celyfe supplied: 99% purity for each peptide, with a measured content of about 91% of label for BPC-157 and 85% for TB-500. The GLOW certificate is being re-issued and is not yet published. The guide to the WOLVERINE Pen notes that the lower total mass reflects fewer components, not a lower concentration of any shared compound. Every Celyfe pen is supplied and labelled for laboratory research use. Nothing on this page is guidance on use in humans or animals.
