They market it as being better or equal to testrogel personally I think klein-becker's testrogel is probably not that potent but then I'm sour because like a dumb ass I paid 85.00 for the oxydrene about 6 mths ago and it sucked. I have to admit I most have split personality because here I am again thinking about buying the testroxin gel form nutrasport. I don't think you'll get many replies I'm willing to bet most think it's a waste of money but if you do but it let me know what your results are also DPS nutrition sells testrogel for about 54.00 and bodybuilding.com sells the Nutrasport version for 39.99 a good 40.00 less than the advertisement.
