hard to say. at the begginig some might have an extra erection but in short terms only. and ofc it depents what u take and wat doses. but in long terms u may fucked up ur dick forever :d
always use the minimal recommended doses (like some products are recommended from for example 20 to 60g, i'd take 20 30 max) and ALWAYS but ALWAYS use TAC products to keep your body healthy.
