I'm now an LG rep, so let's kick off the festivities! Instead of putting up a log for a specific product, I'll be phasing products in and out as this progresses, or stacking them. As some of you may know, I lift to aid my pursuit of progress in judo and BJJ, so I will be putting products through a slightly different wringer than the norm here.
First off will be ASGT. No introduction needed there, it's reputation FAR precedes this log. I am very interested in seeing how it performs from a fight standpoint, as opposed to just lifting.
So far I did one BJJ class on it, and this mornings workout. First impressions:
Energy - totally caught me off guard. I know approximately how much caffeine it has, and expected something else. It creeps up slow, and lingers LONG. Like all day long. At no point have there been jitters. I did crash after the first dose, like 17 hours later.
Strength - too early to tell, but todays workout was very good. I have been on creatine for the last month, so I am already fully saturated, creatine-wise.
Pumps - undetermined as of yet, due to stacking with the last of the GB.
Let's take a peak at one of ASGT's ingredients, ellagic acid (from the LG write-up):
Let's see what else it may do.Ellagic Acid, has an interesting study that shows it to act like the popular post cycle therapy product Nolvadex (R) by blocking estrogen at the cellular level. This gives the body the signal to produce more testosterone, which is a great thing for the serious bodybuilder.

Anticarcinogenic effects of polyphenolic compounds in fruits and vegetables are well established. Although polyphenols naturally occur as combinations, little information is available regarding possible synergistic or antagonistic biochemical interactions between compounds. Identifying potential interactions between polyphenols may provide information regarding the efficiency of polyphenol-containing foods in cancer prevention. The objective of this study was to investigate the interactions of ellagic acid and quercetin with resveratrol, polyphenols which occur in muscadine grapes, with the hypothesis that the selected polyphenols would interact synergistically in the induction of apoptosis and reduction of cell growth in human leukemia cells (MOLT-4). To test this hypothesis, alterations in cell cycle kinetics, proliferation, and apoptosis (caspase-3 activity) were examined after incubation with ellagic acid, quercetin, and resveratrol as single compounds and in combination. Results showed a more than additive interaction for the combination of ellagic acid with resveratrol and furthermore, significant alterations in cell cycle kinetics induced by single compounds and combinations were observed. An isobolographic analysis was performed to assess the apparent synergistic interaction for the combinations of ellagic acid with resveratrol and quercetin with resveratrol in the induction of caspase 3 activity, confirming a synergistic interaction with a combination index of 0.64 for the combination of ellagic acid and resveratrol and 0.68 for quercetin and resveratrol. Results indicate that the anticarcinogenic potential of foods containing polyphenols may not be based on the effects of individual compounds, but may involve a synergistic enhancement of the anticancer effects.

Interesting, because ASGT contains all three substances mentioned above.Ellagic acid potentiates the effect of quercetin on p21waf1/cip1, p53, and MAP-kinases without affecting intracellular generation of reactive oxygen species in vitro.

Anticarcinogenic effects attributed to polyphenols in fruits may be based on synergistic, additive, or antagonistic interactions of many compounds. In a previous study, it was demonstrated that quercetin and ellagic acid interacted synergistically in the induction of apoptosis in the human leukemia cell line, MOLT-4. To investigate possible cellular mechanisms, this study evaluated whether synergistic effects might be detectable within proapoptotic or antiproliferative signal transduction pathways. We found that quercetin and combinations of quercetin and ellagic acid nonsynergistically increased p53 protein levels. In contrast, ellagic acid potentiated the effects of quercetin for p21(cip1/waf1) protein levels and p53 phosphorylation at serine 15, possibly explaining the synergistic effect observed in apoptosis induction. Phosphorylation of the mitogen-activated protein (MAP) kinases, c-jun N-terminal (JNK)1,2 and p38, was also increased by the combination of ellagic acid and quercetin, whereas quercetin alone induced only p38. We further evaluated whether the generation of reactive oxygen species (ROS) and/or quercetin stability were influenced by interactions of ellagic acid with quercetin. Quercetin increased the generation of ROS, which was neither potentiated nor inhibited by ellagic acid. The stability of intracellular and extracellular quercetin was not influenced by the presence of ellagic acid. In summary, quercetin and ellagic acid combined increase the activation of p53 and p21(cip1/waf1) and the MAP kinases, JNK1,2 and p38, in a more than additive manner, suggesting a mechanism by which quercetin and ellagic acid synergistically induce apoptosis in cancer cells.

Ellagic acid is a plant-derived polyphenol, possessing antioxidant, antiproliferative, and antiatherogenic properties. Whether this compound has estrogenic/antiestrogenic activity, however, remains largely unknown. To answer this question, we first investigated the ability of ellagic acid to influence the activity of the estrogen receptor subtypes ERalpha and ERbeta in HeLa cells. Cells co-transfected with an estrogen response element (ERE)-driven luciferase (Luc) reporter gene and an ERalpha- or ERbeta-expression vector were exposed to graded concentrations of ellagic acid. At low concentrations (10(-7) to 10(-9) M), this compound displayed a small but significant estrogenic activity via ERalpha, whereas it was a complete estrogen antagonist via ERbeta. Further evaluation revealed that ellagic acid was a potent antiestrogen in MCF-7 breast cancer-derived cells, increasing, like the pure estrogen antagonist ICI182780, IGFBP-3 levels. Moreover, ellagic acid induced nodule mineralization in an osteoblastic cell line (KS483), an effect that was abolished by the estrogen antagonist. Endometrium-derived epithelial cells (Ishikawa) showed no response to the natural compound by using a cell viability assay (MTT). These findings suggest that ellagic acid may be a natural selective estrogen receptor modulator (SERM).
