High-Stim Pre-Workout
A high-stim pre-workout built for athletes who want serious energy, focus, pumps and intensity when it is time to train. Formulated with full-dose citrulline, beta-alanine and 350mg of caffeine.
High caffeine. Contains 350mg of caffeine per serving. Not intended for anyone sensitive to caffeine. Do not combine with other caffeine sources.
Three ingredients carry the load in Mainline. Here is what each one is in the formula to do, and the exact amount you get per serving.
The pump ingredient. Citrulline is included at a full 6g serving and is used in pre-workout formulas to support nitric oxide production and blood flow during training.
The set-extender. Beta-alanine is dosed at 3.2g per serving and is one of the most commonly researched ingredients in performance formulas for higher-volume training.
This is a high-caffeine product. Each serving contains 350mg of caffeine, which is roughly three to four cups of coffee. Assess your tolerance before using a full serving.

Sharp lemon flavor built for your pre-training ritual.
Tart, cold and clean — the kind of flavor you actually want to finish before a session instead of forcing down. Mixes fast in cold water with a shaker.
One scoop in cold water. Shake it and give it time to settle before you walk in.
Headphones on. First set loaded. The noise drops away.
Set after set. Focus holds where it usually breaks.
Nothing left on the rack. That is the entire point.
We are not going to invent numbers for anyone else's tub. Here is exactly what is in Mainline, next to what you should check on any pre-workout before you buy it.
These are the disclosed key actives per serving. The full ingredient panel is printed on the tub — see the Supplement facts tab.
Follow the directions printed on the product label. Because this is a high-stimulant formula, start with a partial serving to assess your tolerance before using a full serving. Do not exceed the serving size shown on the label, and do not use within several hours of bedtime.

Three words that decide what makes it into a Vital Asset formula and what does not.
Show up when it is inconvenient. The formula is built for people who train whether or not they feel like it.
Every ingredient has a job and a disclosed amount. Nothing is in the tub to look good on a label.
Training is a long game. Build something that still stands when the trend cycle moves on.
Mainline is Vital Asset's high-stim pre-workout in Electric Lemonade. Each serving is formulated with 6g of citrulline, 3.2g of beta-alanine and 350mg of caffeine.
350mg per serving. That is roughly the caffeine in three to four cups of coffee, which puts Mainline firmly in the high-stimulant category. If you are caffeine sensitive, this is not the right product for you.
Follow the timing printed on the label. As a general rule, high-caffeine pre-workouts are taken shortly before training and not within several hours of bedtime.
Servings per container are listed on the Supplement Facts panel on the tub.
Sharp, tart lemonade. It is designed to mix quickly in cold water and go down fast before a session.
Anyone under 18, anyone who is pregnant, nursing or trying to become pregnant, and anyone sensitive to stimulants. If you have a medical condition or take medication, talk to your physician before using any high-caffeine product.
No. Do not stack Mainline with coffee, energy drinks, fat burners or any other stimulant product. One serving already contains 350mg of caffeine.
Store in a cool, dry place with the lid sealed, and keep it out of reach of children. Follow any storage instructions printed on the label.
