Frequently Asked Questions

Yes. Vintage Blast™ will deliver excellent results for men and women wanting a pre-workout supplement to help sustain them through rigorous workouts and competitive events.


Vintage Blast™ is specifically designed to deliver its ingredients over an extended period of time, rather than all at once, by harnessing the ingredients’ different digestive and assimilation properties.


Vintage Blast™ contains no carbs, no sugars, and no calories. The sweetening in Vintage Blast™ is provided by stevia leaf extract, a natural sweetener with zero calories and zero carbs.


Yes. Anecdotally, some bodybuilders say they get even better, longer-lasting pumps and muscle fullness when stacking Vanadyl Sulfate (a key ingredient in Vintage Burst™) with creatine. Vintage Build™ is a great source of high-quality creatine and stacks very well with Vintage Burst™.


Yes. Fat-loss or fat-cutting diets typically require eating less food (i.e., cutting down on your calories). This may cause your energy level to fall and your metabolism to slow, making it harder to lose fat. When you’re on a calorie-reduced diet, you may also be eating fewer antioxidant-rich foods. Besides boosting your energy and metabolism, Vintage Burst™ supports healthy antioxidant levels with Spectra™.


Vintage Burst™ can be taken before any type of exercise. For the best pumps, we recommend keeping your rest between sets between 30 and 60 seconds.
