My experience with TNE has always been beneficial, given one caveat...how high is your weekly testosterone dosing already?
For me personally, if I'm running over 500 to 750 mg a week, TNE seems lackluster unless it's dosed at a minimum of 100 to 300 mg pre-workout.
However, if you are using it within a TRT+ regimen, it is amazing every single time when it comes to drive, focus, and a slightly antagonistic edge. I find I become easily irritated by things I am usually very mellow about, like someone playing on their phone while I'm waiting. In those moments, I'm much more prone to let someone know exactly how I feel.
The symptoms are identical whether you use a water or oil base, outside of the absorption rate. Typically, a water base hits me pretty strongly within an hour. With an oil base, it takes about 1.5 to 2 hours before I am at maximum overdrive. It is also worth mentioning that if you are using high-milligram dosing, especially with a water base you will end up utilizing every injection site you can find. I personally recommend injecting the specific muscle group you intend to work (legs, lats, etc.), as the extra blood volume from training can help alleviate the PIP over the following 24 to 48 hours.
Someone previously mentioned guaiacol. In the old days, using this was common to prevent the compound from crashing. Personally, I avoid it at all costs now because it is horrible for you, and you will taste it all day the moment it hits your bloodstream, it's on your taste buds. Today, we know we can much more easily adjust the BA/BB ratios to achieve equivalent solubility. As well as carrier.
I love my injectable pre-workouts and have used them routinely for years. If I can help further, let me know. Adrol, Dbol, TNE, Blends, so on...
