How to use
-

Take up to two 250mg capsules daily, ideally in the morning with food.
-
2-3 month cycle

-
TAKE WITH FOOD
It's usually best to take Tongkat Ali with food in the morning. Some individuals feel nauseous when taking Tongkat Ali on an empty stomach due to quick absorption or gastrointestinal irritation.
HOW DOES TONGKAT ALI WORK IN THE BODY?
After digestion, Tongkat Ali stimulates the pituitary gland to release more luteinizing hormone and follicle-stimulating hormone into the bloodstream.
The Leydig cells in the testicles detect these hormones as a biological signal to increase testosterone and sperm production.
Increased testosterone levels help to build muscle, increase libido, boost erectile function, decrease stress and enhance your mood.
