Tribulus works good at first

Tribulus works good for the first 2 weeks.my penis and balls hang and feel big.Then it starts working againsed you shutting down your testosterone .then my penis and balls get shriveled and tight and I get premature ejaculation .is there a way to prevent negative feedback by cycling tribulus? .Lets just say 4 on 3 off?

Tribulus doesn’t shut down your T production. In fact it makes your tests to produce more T. It works by increasing your LH hormone which signals your tests to produce more T. When your tests come to know that increase in LH is due to some foreign substance it no more produces extra T but switches back to its normal mode. But it’d not shrivel up and it’d not shut down natural T production.

Try using it for 2 weeks followed by 1 week break. You can also try 5 days on and 2 days off to see how it works.

May I know which brand of trib and the dose you use?

Maybe the placebo effect wore off?

I used to use whatever the GNC stock tribulus was when I was 17/18.. I can honestly say that the increased sensation during ejaculation and extra testicular mass were no placebo =D

Haven’t used it for a while though.. and I didn’t have any shrivelling or any of that when I took it.

If from placebo effect, how would you know?

There aren’t any legitimate studies backing claims that tribulus raises testosterone through any mechanism. The few studies that have been done show it doesn’t.

I’ve been on Trib. for over 5 months & I haven’t noticed any effect on my penis.

Haha fair enough for you to say.. it would have had to be one mad placebo effect though. I don’t think my brain holds that much sway over my body. But if it does.. PE should be a joke.

I got the same effect when I tried two ADD drugs a couple of years ago. Adderall and I can’t think of the name of the other one but they were green capsules.

What brand are you taking? Some brands contain no protodioscins.
