Have been working out for about 2 years now 5' 10" 175lbs started out at 205lbs. 45 years old looking to put on some size and reduce my body fat. Someone has recomended to use Deca, TEST and d-bol for 12 weeks.My question is Can i use Deca only for 12 weeks since it has less side effect and is less toxic to the liver? Or should i use Deca with TEST or DECA with Dbol thanks in advance for you input.
