The heavier of the two boldenone concentrations Pharmacom Labs offer, this vial holds 500 mg per millilitre across 10 ml.
Doubling the concentration does not change the hormone, only the carrier: more solvent, less oil, a denser solution that takes longer to pass through a needle. What it buys is compactness — the same bottle carries twice the material of a 250 mg/ml preparation.
Boldenone undecylenate is used as an injectable androgen and has one of the slowest release curves of the esterified steroids, a consequence of the eleven-carbon chain hung off the seventeen-beta position.
