different results for different people. thats why the reviews you will see are also mixed. example, yung robust, sabi ng iba effective daw. among those na nagsabi effective, meron nagsabi sumakit ulo, meron namang nagsabi walang side effect. also meron din nagsabi na wala naman effect sa kanila yun robust
which is why until now hindi ganun kasikat mga product na to. if there was one pill/lotion/cream or whatever that was truly 100% effective for everyone, then im pretty sure sobrang sikat na nun. example, yung viagra. kaya sikat na sikat siya kasi it works for everyone, kahit walang ED, hindi mixed ang results, it does what it says it does.
but as its different results for different people, the only way to know for sure is to try etong mga titan gel for yourself
