View Full Version : Maybe this will help clear up some questions on natural test boosters.

Hello i did some searching on pubmed. I checked some of the ingredients found in test boosters.I still feel these boosters will not give steroid like results but may at least help those who need a boost.

1st one i checked was Testofen. Results were:

The aim of the clinical study was to evaluate the effect of Testofen, a standardized Trigonella foenum-graecum (Fenugreek) extract and mineral formulation, on male libido (sexual drive, urge or desire) in a double blind randomized placebo controlled study. The study recruited 60 healthy males aged between 25 and 52, without erectile dysfunction and randomized to an oral dose (two tablets per day) of the active treatment (600 mg Testofen per day) or placebo for 6 weeks. The primary outcome measure was the DISF-SR (male) self-administered QOL total score and the four domain scores. The secondary outcome was specific quality of life parameters. Testofen had an overall positive effect on physiological aspects of libido. In particular, there was a significant increase in the subdomains of sexual arousal and orgasm. Testofen had a positive effect on QOL in self-reported satisfaction with muscle strength, energy and well-being but did not have an effect on mood or sleep. Serum prolactin and testosterone levels remained within the reference range. It was concluded that Testofen demonstrated a significant positive effect on physiological aspects of libido and may assist to maintain normal healthy testosterone levels.

2nd one was D- aspartic acid. Results were:


D-aspartic acid is an amino acid present in neuroendocrine tissues of invertebrates and vertebrates, including rats and humans. Here we investigated the effect of this amino acid on the release of LH and testosterone in the serum of humans and rats. Furthermore, we investigated the role of D-aspartate in the synthesis of LH and testosterone in the pituitary and testes of rats, and the molecular mechanisms by which this amino acid triggers its action.

For humans: A group of 23 men were given a daily dose of D-aspartate (DADAVIT) for 12 days, whereas another group of 20 men were given a placebo. For rats: A group of 10 rats drank a solution of either 20 mM D-aspartate or a placebo for 12 days. Then LH and testosterone accumulation was determined in the serum and D-aspartate accumulation in tissues. The effects of D-aspartate on the synthesis of LH and testosterone were gauged on isolated rat pituitary and Leydig cells. Tissues were incubated with D-aspartate, and then the concentration (synthesis) of LH and cGMP in the pituitary and of testosterone and cAMP in the Leydig cells was determined.

In humans and rats, sodium D-aspartate induces an enhancement of LH and testosterone release. In the rat pituitary, sodium D-aspartate increases the release and synthesis of LH through the involvement of cGMP as a second messenger, whereas in rat testis Leydig cells, it increases the synthesis and release of testosterone and cAMP is implicated as second messenger. In the pituitary and in testes D-Asp is synthesized by a D-aspartate racemase which convert L-Asp into D-Asp. The pituitary and testes possesses a high capacity to trapping circulating D-Asp from hexogen or endogen sources.

D-aspartic acid is a physiological amino acid occurring principally in the pituitary gland and testes and has a role in the regulation of the release and synthesis of LH and testosterone in humans and rats.

I hope this helps with some of the questions.

I gotta tell you, the best way to "clear up" any questions on TB's is to just try them. If you are expecting even 20% of what they hype themselves up to be, you'll be clear that you've wasted your hard earned cash on them. They clearly cost too much and really do next to nothing for the natural lifter.

The very fact they can be discussed here and now on this site is clear proof they're nearly worthless. Think about that....

I do think many actually do DO something, it's clear they are DOING something when you use them. It's just that a great diet and lifting plan will DO way much more without any pills at all. It's just the plain truth dude. ;)
