Buy KLOW peptide: 80 mg vial or 240 mg pen
KLOW combines GHK-Cu, BPC-157, TB-500 and KPV in a fixed 5:1:1:1 ratio. The 80 mg vial arrives as powder; the 240 mg pen contains 3 mL of prepared liquid. One pen holds three vials’ worth of blend by label amount. Both are research-labelled formats. [1]

KLOW vial and pen compared
| Specification | 80 mg vial | 240 mg pen |
|---|---|---|
| GHK-Cu | 50 mg | 150 mg |
| BPC-157 | 10 mg | 30 mg |
| TB-500 | 10 mg | 30 mg |
| KPV | 10 mg | 30 mg |
| Total blend | 80 mg | 240 mg |
| Ratio by mass | 5:1:1:1 | 5:1:1:1 |
| Mixing | Powder needs reconstitution | Already mixed |
| Liquid volume | Depends on preparation | 3 mL |
| Concentration | Depends on final volume | 80 mg/mL |
| Liquid ingredients | Depend on the specified diluent | Water + 0.9% benzyl alcohol |
The pen contains more blend, with the same ingredient proportions. Changing format does not add another peptide or let you adjust KPV separately. Increasing a portion increases all four ingredients together. [1]
KLOW 80 mg vial: powder and flexible concentration
The vial contains 50 mg GHK-Cu and 10 mg each of BPC-157, TB-500 and KPV. All four are already blended into one blue freeze-dried cake. Blue is the expected colour from the copper complex; colour alone does not verify purity or amount. [2]
The 80 mg figure is the total content. It becomes a concentration only after the final liquid volume is known. An 80 mg vial prepared to 2 mL would contain 40 mg/mL; at 3 mL it would contain about 26.67 mg/mL. These are calculation examples, not a prescribed mixing method.
A 4 mg total portion contains 2.5 mg GHK-Cu + 0.5 mg BPC-157 + 0.5 mg TB-500 + 0.5 mg KPV. That gives twenty mathematical portions per vial before losses and discard limits. Adding more water changes the volume representing that amount, without creating more portions.

KLOW 240 mg pen: already mixed at 80 mg/mL
The pen contains 150 mg GHK-Cu and 30 mg each of BPC-157, TB-500 and KPV. Its liquid is already prepared in water with 0.9% benzyl alcohol. No water needs adding to the cartridge. [1]
The supplied device configuration uses 300 marked units per 3 mL cartridge: 0.01 mL per marked unit. At 80 mg/mL, each marked unit represents 0.8 mg total blend—0.5 mg GHK-Cu plus 0.1 mg of each other ingredient. This scale was supplied for the featured device; a mechanical click has not been independently equated to one marked unit.
For a 4 mg calculation, the pen volume is 0.05 mL, equivalent to five marked units on that specified scale. The same amount in a vial prepared to 2 mL would occupy 0.1 mL. Copying a volume from the vial to the pen would double the amount.
The pen’s larger content does not guarantee more usable portions. Priming, liquid left in the cartridge and the applicable discard date reduce usable yield; their exact values have not been supplied.
The four ingredients on the label
GHK-Cu
Five of every eight milligrams are the copper–peptide complex. The 50 mg vial amount is not 50 mg of elemental copper.
BPC-157
10 mg per vial or 30 mg per pen. The supplied report identifies the 15-amino-acid BPC-157 sequence.
TB-500
This product specifies full-length N-acetyl thymosin beta-4, a 43-amino-acid molecule. Match that identity when comparing another label.
KPV
The three-amino-acid sequence Lys-Pro-Val. The vial adds 10 mg KPV to the 50/10/10 mg composition of the GLOW 70 mg vial.
The certificate confirms the identity of all four components. These percentages describe the label composition; they are separate from the laboratory’s chromatogram peak percentages. [2] For the ingredient research, see KLOW benefits; for the three-peptide alternative, compare GLOW vial and pen specifications.
Compare value against three vials
Divide the vial price by 80 and the pen price by 240. The result is price per milligram of the same 5:1:1:1 blend. One pen and three vials both contain 240 mg by label total.
| Pen price | Nominal blend value |
|---|---|
| Less than three vial prices | Lower price per milligram |
| Exactly three vial prices | Equal price per milligram |
| More than three vial prices | Higher price per milligram |
Preparation materials, delivery and unused liquid still affect the final cost. Three sealed vials can be prepared separately; the pen holds the whole 240 mg in solution from the start. A larger label total has less value if part of the product reaches its discard date unused. Current selling prices and ordering links have not been provided.
Storage: sealed powder and prepared liquid
−20°C / −4°F
Keep the vial dry and protected from light. The lot’s 15 September 2028 retest date applies to stored powder.
2–8°C / 36–46°F
Protect from light. Keep the pen in its carton and do not freeze it. No verified in-use day limit was supplied.
The normal pen solution is clear blue to blue-violet. Its handling instructions require discarding a pen that has frozen, become cloudy or changed from that appearance. The powder’s retest date does not become the expiry date of a mixed vial or opened pen. [1]
Redacted KLOW certificate of analysis
KLOW blend — powder lot PL-2609-057
Two sampled powder vials from lot PL-2609-057. Shown beside both formats; no finished-pen testing or exact pen-batch linkage is supplied.
Open redacted COACertificate PL-26-00057 covers powder lot PL-2609-057. Two vials were sampled from a 250-unit lot. It records 99.66% combined HPLC area purity, all four ingredient identities, 0.06 EU/mg endotoxin, 2.1% water and no growth after 14 days in the sterility test. [2]
The testing is in-house. No independent laboratory report is attached. HPLC area purity measures the share of detected chromatogram peaks belonging to the four components; it does not separately weigh the 80 mg fill or verify each labelled ingredient quantity.
The same redacted two-page PDF is available beside both products. Its tested sample is powder. A finished-pen assay, finished-cartridge sterility result and confirmed link to the pen’s batch were not supplied. The report retains its original lot, dates, methods and signatures.
Questions & answers.
Is the KLOW pen 80 mg or 240 mg?
It contains 240 mg total. The 80 mg/mL concentration multiplied by its 3 mL fill gives 240 mg. The powder vial contains 80 mg total.
Does the KLOW pen need mixing?
No. The blend is already dissolved in the cartridge. Its solution contains water and 0.9% benzyl alcohol; do not add more water.
Does KLOW have the same ingredients as GLOW?
KLOW contains the GLOW ingredients—GHK-Cu, BPC-157 and TB-500—plus KPV. This 80 mg vial adds 10 mg KPV to the 50/10/10 mg GLOW vial composition.
Can the amount of KPV be adjusted separately?
No. The fixed 5:1:1:1 blend changes all four ingredient amounts together. More liquid changes concentration without changing their proportions.
Does one pen equal three vials?
Yes by label content: 240 mg in one pen equals three 80 mg vials. Usable yield can differ because of preparation losses, priming, residual liquid and discard limits.
Are needles and mixing supplies included?
The vial specification identifies a sealed powder vial. The pen specification describes a prefilled cartridge with a fitted needle. Additional needles, diluent and other accessory quantities are not confirmed.
Does the supplied COA test the finished pen?
No. It reports tests on two powder vials from lot PL-2609-057. It is displayed with the pen as a blend-lot reference; finished-pen testing and the exact batch linkage were not supplied.
