Frequently Asked
Questions
What does pre-workout do?
Pre-workout supplements work by acutely enhancing multiple aspects of your physical and mental performance, especially strength, stamina, blood flow, perceived energy, and focus.
Is pre-workout good or bad for you?
The answer depends entirely on the quality, formula, and usage of the pre-workout in question. Some pre-workouts may be “bad” in the sense that they contain exorbitant stimulants or even designer drugs, leading to adverse effects. In contrast, other pre-workouts, such as Transparent Labs Bulk, can be “good” by providing evidence-based ergogenic ingredients in efficacious, well-tolerated doses.
Can beginners take pre-workout supplements?
Absolutely. We recommend starting with a ½ serving of whichever pre-workout you use, especially if it contains caffeine. If the effects are underwhelming after a ½ serving, try a full serving before your next workout and reassess.
When should I take pre-workout for best results?
When taking a pre-workout on an empty stomach, 20-30 minutes before exercise is ideal. If you take a pre-workout within three hours of eating a sizable meal, 30-45 minutes before exercise should suffice since food in the GI tract slows the absorption of ingredients.
How long does pre-workout last in your system?
On average, the effects of pre-workout supplements last between 1.5 to 2.5 hours but may last up to four or five hours in caffeine-sensitive users. The circulating half-lives of most pre-workout ingredients are less than five hours.
What is the difference between stim and non-stim pre-workouts?
Stim pre-workouts include caffeine and potentially other stimulants to boost alertness and perceived energy. Conversely, non-stim pre-workouts are free of caffeine and other stimulants. Instead, they may contain amino acids, herbal extracts, vitamins, minerals, and other ergogenic aids that enhance athletic performance without directly stimulating the central nervous system.
