Choose the vial or preloaded pen
The range has three products: a 50 mg powder blend, a 70 mg powder blend and a preloaded autoinjector. The two vials differ in their ingredient proportions as well as their total contents. The pen has a different presentation and a larger labeled total.123

What changes between the three products?
The 70 mg vial is not simply a scaled-up 50 mg vial. It contains 15 mg more GHK-Cu and 5 mg more BPC-157, while TB-500 stays at 10 mg. That changes the ingredient balance from 7:1:2 to 5:1:1.12
| Product detail | 50 mg vial | 70 mg vial | Autoinjector |
|---|---|---|---|
| Total labeled blend | 50 mg | 70 mg | 150 mg nominal |
| GHK-Cu | 35 mg | 50 mg | 107 mg |
| BPC-157 | 5 mg | 10 mg | 21.4 mg |
| TB-500 (Thymosin β4) | 10 mg | 10 mg | 21.4 mg |
| Ingredient mass ratio | 7:1:2 | 5:1:1 | Approximately 5:1:1 |
| Presentation | Freeze-dried powder | Freeze-dried powder | 3 mL preloaded solution |
| Concentration as supplied | Powder; no liquid concentration | Powder; no liquid concentration | Labeled 50 mg/mL |
For a like-for-like comparison, use the amount of each ingredient rather than the total milligrams alone. A higher total tells you there is more labeled material; it does not establish a better cosmetic or recovery result.
The pen is labeled 150 mg in 3 mL. Its listed component amounts are 107 mg, 21.4 mg and 21.4 mg, which sum to 149.8 mg. Both the nominal label and the supplier's component figures are retained here without altering them.
Powder vial or preloaded autoinjector?
50 mg or 70 mg vial
Both contain a freeze-dried blend. The ingredient quantities are fixed for that formula, while a solution concentration would depend on the preparation specified for the laboratory procedure.
3 mL autoinjector
The cartridge arrives preloaded with solution. There is no dry powder to dissolve. The supplied label gives a total concentration of 50 mg/mL and a nominal total of 150 mg.
Choose by the format and composition your research requires. The 50 mg and 70 mg vials offer two different ingredient ratios. The pen offers a ready-filled presentation with component proportions close to the 70 mg vial.123
Preloaded describes the product's physical state. It is not a personal dosing instruction, and a pen setting should not be inferred from the total concentration. The GLOW dosage page is the separate place for amount and concentration questions.
Inside the GLOW pen

3 mL · 50 mg/mL
Each pen's specification lists 107 mg GHK-Cu, 21.4 mg BPC-157 and 21.4 mg TB-500 (Thymosin β4). It describes an aqueous solution in bacteriostatic water containing 0.9% benzyl alcohol, inside a glass cartridge.
Sealed storage: 2–8 °C in the original carton, protected from light. The safety-data-sheet identifier is PL-SDS-070.3
Read the pen specificationThe powder vials have different sealed-storage instructions: the supplied lot certificates state −20 °C, desiccated and dark. Keep the storage instructions matched to the product rather than using one rule for every format.12
See the actual report before you choose
The two vial reports are available below in their original, two-page form. The 50 mg record reports 99.70% RP-HPLC area purity; the 70 mg record reports 99.72%. Each also reports three component identities confirmed by LC-MS.12

Questions before choosing a GLOW product
Is the 50 mg vial the same formula as the 70 mg vial?
Does the autoinjector contain powder?
No. The supplied specification describes a preloaded 3 mL aqueous solution. Its label gives 50 mg/mL, with a nominal total of 150 mg.3
Are these one-ingredient products?
No. Each option combines GHK-Cu, BPC-157 and TB-500. The cards show the amount of each component; the headline 50 mg, 70 mg or 150 mg refers to the combined labeled amount.
Can I download the COA before ordering?
Yes. The report cards above open the original PDFs in a new tab. The Quality + COA page also has downloads, chromatograms and certificate-verification details.
Does 99.72% mean the 70 mg vial will work better?
No. It is the reported chromatographic area purity for that lot, not a score for cosmetic results. The two vial formulas also contain different ingredient amounts.
How do I identify the right batch report?
Where can I ask a product question?
