Solvent Math

Direct Concentration Formula

Determines solution potency in micrograms per milliliter based on dry peptide mass and added liquid volume.

Formula (Mass × 1,000) / Vol
KLOW Example 50,000 mcg / 2.0 mL
Result 25,000 mcg/mL
  • Governs base solute-to-solvent concentration
  • Accounts for total mass vs active compound mass
  • Linear scaling across any diluent volume
Syringe Math

Injection Draw Volume Formula

Converts a clinical target microgram prescription into physical milliliters and insulin syringe unit marks.

Formula (Target / Conc) × 100
KLOW Example (2,000 / 25,000) × 100
Result 8.0 Units (0.08 mL)
  • Translates microgram targets into physical barrel lines
  • Calibrated for standard U-100 insulin syringes
  • Guarantees zero fractional roundoff dosing errors

STEP-BY-STEP PROOF

Mathematical Proof of Proportional Dosing

In blended multi-peptide vials such as the 70 mg Glow Triad or 80 mg KLOW Quad, the ratio between compounds remains chemically fixed during the manufacturing lyophilization process. When solvent is added, each constituent peptide dissolves uniformly throughout the aqueous diluent.

Because all compounds share identical solution volume, the microgram yield of each secondary peptide is directly proportional to its mass fraction relative to the benchmark peptide, GHK-Cu. For example, in an 80 mg KLOW vial containing 50 mg GHK-Cu and 10 mg each of BPC-157, TB-500, and KPV:

Compound Vial Mass Mass Fraction Yield Formula Delivered Yield
GHK-Cu 50 mg 62.5% Target Prescription Benchmark 2,000 mcg (2.0 mg)
BPC-157 10 mg 12.5% 2,000 mcg × (10 mg / 50 mg) 400 mcg (0.4 mg)
TB-500 10 mg 12.5% 2,000 mcg × (10 mg / 50 mg) 400 mcg (0.4 mg)
KPV 10 mg 12.5% 2,000 mcg × (10 mg / 50 mg) 400 mcg (0.4 mg)

Diluent Tonicity & Tissue Permeability

Bacteriostatic 0.9% benzyl alcohol sterile water functions as an isotonic carrier that prevents hypotonic cellular lysis during subcutaneous administration. When diluting lyophilized polypeptide cakes, maintaining an osmolality between 280 and 310 mOsm/kg ensures rapid tissue diffusion without cellular edema.

Preservative 0.9% Benzyl Alcohol
Target Osmolality 280–310 mOsm/kg
pH Range 4.5 to 7.0 (USP)

Methodology & Calculation Inquiries

COMMON QUESTIONS

Frequently Asked Clinical Inquiries

01 Why is C1V1 = C2V2 the foundational law of peptide reconstitution?

The dilution law (Concentration 1 × Volume 1 = Concentration 2 × Volume 2) embodies the law of conservation of mass. It establishes that the total mass of peptide molecules remains invariant regardless of how much liquid solvent is introduced into the vial.

02 Why should sterile bacteriostatic water be used instead of sterile saline?

Bacteriostatic water contains 0.9% benzyl alcohol, an antimicrobial preservative that prevents bacterial proliferation over multiple needle punctures across a 30-day period. Plain sterile saline contains no preservative and must be discarded within 24 hours of first puncture.

03 Does adding 3.0 mL of water dilute the therapeutic effectiveness of the dose?

No. Adding more water alters liquid volume but does not diminish peptide mass. Drawing 12.0 units of a 3.0 mL solution delivers the exact same 2,000 mcg of GHK-Cu as drawing 8.0 units of a 2.0 mL solution, while reducing localized tissue irritation.
