Androgenic-anabolic steroid administration significantly lowers serum Lipoprotein(a) [Lp(a)] concentrations, which may have a beneficial effect on cardiovascular risk, although this benefit is offset by the adverse effects on other lipids.

AAS use tends to lower Lipoprotein(a), which is generally considered a good thing for heart health. However, because AAS simultaneously destroys your 'good' cholesterol (HDL) and raises 'bad' markers, you cannot assume the Lp(a) benefit cancels out the damage. The net effect on heart disease risk is likely negative and complex.

Serum Lp(a) declined from 189 (315) to 32 (63) U/l... Administration of AAS for 14 weeks was associated with slower recovery to pretreatment concentrations than administration for eight weeks.
