nolva is agonistic in adipose tissue (it causes fat gain, at least in menopausal women).
where did you gain the fat, if it more handles, lowback and lower abs (particularly if its soft in character) then estrogen is the likely culprit. Using aromasin or AIFM in conjunction with yohimburn ES (blocking the A2 receptor) would be beneficial in this situation. if the fat is more central belly fat and there is distention (intraabdominal fat) then insulin issues may be the more likely cause, in that case supplements like glucorell and green tea extract can be helpful as well as increasing cardio and adjusting diet (avoid sugar and high fructose intake, avoid hydrogenated oils, limit saturated fats).
