I am lucky to live in the tropics where lots of benificial herbs/ natural ingredients are easily available. These herbs have been around for centuries, knowledge passed down from our great great ancestors. Also scientifically proven; my brother is a biochemist who is doing research on some of these medicianal plants. Just want to share some of my knowledge on supplements/ herbs that really works for me.. sure will work on u guys as well -euricoma longifolia/ tongkat ali/ longjack -cordyceps -Ginseng -Ashwagandha/ withania -tribulus -bee polen (my father gave me this supplement after i had my 5 stiches and cuts/ bruises from an accident. The wound healed super fast. Noticed some 'side effect'; woke up in the middle of the night by intense erection). -black seed At first, trying these herbs to improve endurance in sports and to gain some muscles from my workout (i m a hard gainer). Really helped to increase stamina and improve sport endurance, also gain some muscle.. however still not satisfied My personal guarantee that these supplements have tremendous effect on mens' health. Have been supplementing with these herbs for more than 2 years. safe and no side effect. surely will make you exXxtra hard and horny ..however it is wise to consult your physician before taking any supplements.
