Best product for increasing free testosterone

Without a doubt, HCGenerate (and one of my favorites BRIDGE) are phenomenal. I am running low on TestForce2 (chelated DAA w/sarcosine) and don't know whether or not to re-up, because Nelson has expressed some misgivings about it's legitimacy, so I'm just waiting to hear back :)

try bulk daa ..it works i can tell you ,,,try them especially bulk daa its the cheapest supp out there and gave me better results than a 65 dollar test booster!!

Well I've REALLY enjoyed TestForce2 (DAA + Sarcosine that has been chelated) along with HCGenerate and BRIDGE. I usually shy away from buying bulk, believe it or not, because of the rampant state of the industry selling bunk powders or engaging in either incorrect or knowingly poor sourcing practices. There's no way as a consumer to totally protect yourself however, so I only purchase from companies I trust in and have earned my confidence and faith be it through cGMP/ISO certification, or having their items produced at an FDA inspected facility.

Do you have a link to the study? Sounds fishy.

Oh yeah, it's that landmark study performed in Italy that the current craze regarding DAA supplementation is founded upon. The mean ascension in serum T concentrations were elevated 40% after only 12 days of administration at a very low 3g/day dosage.

As I said before, this study earned such note because it concerned that rare specific demographic we're all in search of to gather relevant data: Trained male humans, already at the peak of physiological T production (20-30yr olds).

Reproductive Biology and Endocrinology | Full text | The role and molecular mechanism of D-aspartic acid in the release and synthesis of LH and testosterone in human and rats

I assumed since I am taking more than double the dosage used in this human investigation, along with a receptor up-regulating potentiator coupled with the fact the DAA itself is chelated to hugely amplify the water solubility (75x) and in-vivo absorption rates, I was on the right track - especially when taken in concert with HCGenerate and BRIDGE. The results I have felt, have been profound.

From the research site (below), here is an excerpt:

Methods

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.
Results

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.
Conclusion

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.


BUMP for Nelson :)
 
I'm sorry, maybe I'm missing something. Where did it say the dosage was 3 grams? And how was it administered?
