This is because the 5-alpha reductase enzyme acts to decrease the potency of nandrolone, while in contrast lots of other anabolic steroids are untouched by this enzyme, and testosterone's strength is really increased by it.
ນີ້ແມ່ນຍ້ອນວ່າ enzyme 5-alpha reductase ເຮັດເພື່ອຫຼຸດຜ່ອນຄວາມສາມາດຂອງ nandrolone, ໃນຂະນະທີ່ໃນທາງກົງກັນຂ້າມຫຼາຍ steroids anabolic ອື່ນໆແມ່ນບໍ່ໄດ້ຮັບຜົນກະທົບໂດຍ enzyme ນີ້, ແລະການສັກຢາຂອງ testosterone ແມ່ນຕົວຈິງແລ້ວເພີ່ມຂຶ້ນໂດຍມັນ.
