Frequently Asked Questions
Find answers to common questions about our products.
Pre-workout supplements are usually taken before training to help with energy, focus, pumps, or performance. Intra-workout supplements are taken during your session to help you stay fueled while you train. If your workouts are long or intense, amino products from our EAAs and BCAAs collection can be a smart option to sip between sets.
Start with how much stimulation you want. High-stim pre-workouts are built for strong energy, while moderate-stim options can feel easier to use on a regular schedule. Stim-free formulas are a better fit if you train late or want pumps without caffeine. If pumps are your main goal, you can also browse citrulline supplements.
Most pre-workout supplements are taken before training, usually close enough to your workout that you feel the effects when your session starts. Always follow the product label, especially with caffeine-based formulas. If you train later in the day, a stim-free or lower-stim option may be easier to fit into your routine.
Yes, many people use pre-workout and creatine in the same routine. Pre-workout is usually used for the session itself, while creatine works best when taken consistently over time. Some pre-workouts already include creatine, so check your label before adding more. You can shop standalone options in our creatine supplements collection.
You do not need one, but a shaker bottle makes powders easier to mix at the gym or on the go. It also helps if you use an intra-workout drink and want to sip it throughout training. For an easier setup, browse our shaker bottles and blenders.
