One hundred milligrams per millilitre is the old pharmacy strength for nandrolone decanoate, and it is what Maxtreme use here, spread across ten single-use ampoules.
The practical difference from the concentrated versions lies in the carrier rather than the hormone. Less steroid per millilitre means less solvent, a thinner oil and an easier passage through a fine needle, in exchange for a larger volume holding the same quantity of active. What is dissolved in it is unchanged: a long-chain ester of 19-nortestosterone that releases slowly from the injection site over a period of weeks.
