Never thought of that (in regards to 1RM changes). Good catch.studies are always a little suspect. For instance, look at the data on their diet. Placebo was scarfing down calories, at like 700 cals more than the test group by week 8, and yet no significant difference in diet was noted. Yet a significant difference in bodyfat was noted. Since there is nothing to suggest that testofen is actually lipolytic, it's pretty obvious where the statistical significance came from.
To make matters worse, at baseline, the members of the placebo group were lighter (by about 12 lbs, yet eating more) and had a lower baseline bodyfat % (which makes it easier to gain bodyfat as the study progresses).
Lastly, I find it odd that their 1 RM increases in the fenugreek group, yet working reps and peak power changes were not statistically different between the two groups. What aspect of fenugreek allows one to move more weight on a single repetition, but not with 80% of 1RM? We typically observe this effect with stimulants...not herbs.
