Sustanon-style preparations combine multiple testosterone esters within one injectable formulation. The individual esters may have different release characteristics, influencing how testosterone is released after administration.
The product name identifies a 300 designation, but the exact ester composition should be verified from the product packaging. Testosterone exposure can affect fertility, endogenous hormone production, hematocrit, cholesterol, prostate-related parameters, and cardiovascular health.
