I used Tribulus for YEARS as a Natural bodybuilder(Until i made the leap

) It is the MOST EFFECTIVE legal supplement(and more effective than certain illegal drugs) at rasing ENDOGENOUS levels of testosterone(and possibly other androgens). HOWEVER--not ALL TRIB IS CREATED EQUAL! MOST trib is GARBAGE, not containg ANY or very LITTLE of the ACTIVE ingredient known as PROTODICOCIN--which is a steroidal saponin that is responsible for triggering the onset of LH and FSH release--subsequently elevating test levels to the HIGH normal range(+2,000/nl). You MUST have a product containing at LEAST 10% PROTODICION--NOT just "Frustanol Saponins". The best product on the market is Tribex, followed by Tribestan and Vitrix. WORTH EVERY PENNY. WHILE ON cycle, your balls will stay plump. And used in conjunction with clomid as PCT will enable you to retain more gains than ever though possible. As for HAIRLOSS--YES it is possible. i speak from experience. If you are genetically predisposed, the elevated DHT can have its affect. It should be VERY MINOR however. ALSO...use another herb known as Eurycoma Longfolia, or "Tongkat Ali".....GOOD SHIT.....
