Baby Safety / Compounds / Nandrolone

Is Nandrolone safe for babies and kids?

Elevated risk for kids

Infants have immature drug-metabolizing enzymes (CYP450 ontogeny), reduced renal clearance, and different volume of distribution. Accidental exposure or breast milk transfer of Nandrolone poses heightened risk.

What is nandrolone?

The IUPAC name is (8R,9S,10R,13S,14S,17S)-17-hydroxy-13-methyl-2,6,7,8,9,10,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-one.

Also known as: (8R,9S,10R,13S,14S,17S)-17-hydroxy-13-methyl-2,6,7,8,9,10,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-one, 19-Nortestosterone, Nortestosterone, 19-Norandrostenolone.

Risk for babies

Elevated risk

Infants have immature drug-metabolizing enzymes (CYP450 ontogeny), reduced renal clearance, and different volume of distribution. Accidental exposure or breast milk transfer of Nandrolone poses heightened risk.

Neonates and infants up to 12 months have incomplete blood-brain barrier development, immature Phase I/II metabolic enzymes (particularly CYP3A4, UGT1A1), and higher gastrointestinal permeability. Equivalent doses produce higher internal concentrations and longer residence times.

What to do: Minimize infant exposure through source control. For breastfeeding mothers: reduce maternal exposure. For formula-fed infants: use certified low-migration bottles and verified water sources. Consult pediatrician regarding any concerns.

Risk for pregnant and nursing people

High risk

Nandrolone poses pregnancy risk through potential teratogenicity, altered pharmacokinetics (increased blood volume, changed CYP activity), and placental transfer. FDA pregnancy category should be evaluated.

Known reproductive toxicant (GHS H360) or confirmed endocrine disruptor. Placental transfer is presumed. Fetal exposure during critical developmental windows may cause structural malformations, growth restriction, or functional deficits.

What to do: Minimize exposure during pregnancy and lactation. Consult healthcare provider regarding specific risks. Consider alternative products with lower hazard profiles.

AgencyYearClassificationNotes
IARC (androgens as anabolic steroid drug class classified Group 2A in Vol 100A, 2012; nandrolone as individual compound within this class)2012IARC Group 2A for androgenic anabolic steroid drug class; Schedule III controlled substance (USA DEA); anabolic androgenic steroid (AAS); performance-enhancing drug of abuse; FDA-approved as nandrolone decanoate for anemia of chronic renal failure and HIV wasting; hepatotoxicity less than 17α-alkylated AAS; world anti-doping agency (WADA) prohibited substance; not classified for carcinogenicity by NTP, EFSA, or US EPA as individual compound

Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
