>Clomid is a bit more expensive, but it will increase your ejaculate volume dramatically. It also raises T levels.
I’m very skeptical that Clomid will do much for load size. I took Nolvadex (basically the same thing) for a few months and nothing changed.
Both Clomid and Nolvadex (tamoxifen) are selective estrogen receptor modulators. Any increase in testosterone comes about from the drugs reducing the estrogen feedback to the hypothalamus. The brain sees estrogen as being low, estrogen level being one of the feedback mechanisms for testosterone production, and LH and FSH secretion increases in response.
However, this doesn’t necessarily result in a higher level of free T. Results vary tremendously in the abstracts I’ve read. Some show increases of T; others don’t.
According to the most knowledgeable guys on bodybuilding groups/forums, tribulus terrestris doesn’t live up to the hype of those who are selling it.
If it helped you, great, but that probably isn’t the norm. It’s like the damiana that greatly increased the size of one guy’s balls (search for the thread here). Others tried it and didn’t get the same result. Another guy at PE Forums had increased load size from taking maca. RB and I both tried it (I used the exact same brand), with no effect.
