The argument that Anavar (Oxandrolone) is the perfect and safe tool for pubertymaxxing because it is more potent than testosterone, does not aromatize into estrogen, stimulates bone growth in children, and supposedly does not close growth plates is a dangerous misconception
High doses of androgens in Anavar directly cause accelerated skeletal maturation. In medicine, it is prescribed to children with growth disorders exclusively in micro-doses under strict X-ray monitoring of bone age. If taken uncontrollably during puberty, the growth plates will close several years ahead of schedule: after a brief initial height spike, linear bone elongation will completely freeze, leaving your final height well below your genetic potential. Furthermore, any synthetic anabolic inevitably suppresses your body's own testosterone production and shuts down the HPTA (hypothalamic pituitary testicular axis), which can permanently disrupt your hormonal balance during crucial developmental years
