Hormonal

Self-administration of polydrug androgenic-anabolic steroid (AAS) regimens for 8-14 weeks significantly decreases HDL-C, HDL2-C, HDL3-C, and Apo-A1, while increasing Apo-B, creating a highly atherogenic lipid profile.

Using multiple anabolic steroids at high doses significantly worsens your cholesterol profile by lowering 'good' cholesterol (HDL) and raising 'bad' markers (Apo-B). This effect is not subtle; it creates a high-risk state for heart disease that does not immediately resolve after you stop using the drugs, especially if you use them for longer periods (14 weeks vs 8 weeks).

AAS administration led to decreases in serum concentrations of HDL-C (from 1.08 (0.30) to 0.43 (0.22) mmol/l), HDL2-C (from 0.21 (0.18) to 0.05 (0.03) mmol/l), HDL3-C (from 0.87 (0.24) to 0.40 (0.20) mmol/l, and Apo-A1 (from 1.41 (0.27) to 0.71 (0.34) g/l), whereas Apo-B increased from 0.96 (0.13) to 1.32 (0.28) g/l.

Why this rating

Study 1 is a prospective, non-blinded investigation with a control group, but lacks randomization and blinding, introducing potential bias.
