What is Equipoise (Boldenone Undecylenate) 300mg/mL?

Equipoise 300mg/mL is a higher-concentration boldenone undecylenate preparation providing 50% greater boldenone delivery per mL vs the 200mg/mL formulation. Maintains the same long-acting undecylenate ester kinetics (~14–21 days) while enabling more concentrated dose delivery for protocols requiring higher boldenone exposure per injection volume. Research use only.

Research Applications

High-Concentration Boldenone PK

300mg/mL vs 200mg/mL — dose-volume normalised serum AUC and depot formation comparison

Dose-Response Erythropoiesis

EPO upregulation and haematocrit at higher boldenone concentration — dose-response modelling

Volume-Efficient AAS Research

Equivalent boldenone dose in 67% of injection volume — depot tolerability and bioavailability

Undecylenate Depot Concentration

High-concentration ester depot release kinetics — crystallisation and solubility at 300mg/mL

Reduced Aromatisation Androgen

C1-2 double bond boldenone at higher dose — estradiol conversion ceiling, aromatase saturation

Frequently Asked Questions

How is this QSC injectable supplied?
QSC injectable solutions are supplied ready-to-use — no reconstitution required. Each vial contains the stated concentration in pharmaceutical-grade carrier (oil or aqueous). Draw using a sterile syringe appropriate for the solution viscosity.
How should this QSC injectable be stored?
Oil-based solutions: store at room temperature (15–25°C), away from direct sunlight — do not refrigerate as cold temperatures can cause crystallisation. Aqueous solutions: store at 2–8°C. Properly stored, injectable solutions are stable for 2–3 years.
What purity is this QSC injectable and how is it verified?
All QSC injectable compounds are ≥99% pure by HPLC on every production batch, with MS-confirmed identity. COA is published on the product page and independently verifiable at verify.janoshik.com.
🧪 Peptide Research Tools: Use QSC’s free peptide calculators — reconstitution, BAC water, dosing, half-life, and mixing charts.
