This is due to the fact that the 5-alpha reductase enzyme behaves to decrease the strength of nandrolone, while in compare lots of other anabolic steroids are untouched by this enzyme, and testosterone's strength is actually boosted by it.
ນີ້ແມ່ນຍ້ອນວ່າ enzyme 5-alpha reductase ເຮັດເພື່ອຫຼຸດຜ່ອນຄວາມສາມາດຂອງ nandrolone, ໃນຂະນະທີ່ໃນທາງກົງກັນຂ້າມຫຼາຍ steroids anabolic ອື່ນໆແມ່ນບໍ່ໄດ້ຮັບຜົນກະທົບໂດຍ enzyme ນີ້, ແລະການສັກຢາຂອງ testosterone ແມ່ນຕົວຈິງແລ້ວເພີ່ມຂຶ້ນໂດຍມັນ.
