STAMINA Pre-Workout Energy Powder



As women, we pack a lot into a 24-hour day — fitness, work, family — and let’s face it, sometimes it’s exhausting! STAMINA can help you conquer whatever the day brings with a dose of natural energy from sources like B vitamins and green tea extract. In addition, amino acids not only support muscle health but also slow caffeine absorption for sustained energy that lasts all day. Each serving contains about as much caffeine as a cup of coffee, so no crazy jitters here — just the perfect pick-me-up for women in motion.*

Ways to Enjoy

Mix + Blend

Get to know our ingredients.

What’s inside, you ask? Just about everything you need to get (and stay!) energized all day long. Best of all, our formulas are backed by science and research, so there are no guessing games or secrets when it comes to our ingredients. STAMINA, for example, contains natural energy sources such as green tea extract and vitamins B6 + B12, which provide sustained energy before your workout (and long after, for that matter). Plus, we’ve supplemented this pre-workout with electrolytes for hydration and amino acids for muscle health, leaving you energized, invigorated, and ready to run the world.

Power in numbers.

You might have noticed a little number on the corner of our packaging — that digit signifies how each PRTCL product fits into your daily routine. Each one of our nutritional supplements for women was designed to work in tandem, helping you maximize results and reach your health and fitness goals.

Here’s the lineup:

01 | ESSENTIAL: A nutritious dose of fortified whey protein powder.

02 | STAMINA: An energizing pre-workout for any time of day.

03 | REPAIR: A recovery formula perfect for post-workout. 

04 | SUPPORT: A vitamin-packed immunity booster.

Girl, you got this.

At PRTCL, we know that women need more from their nutritional supplements — more nourishment for our physical goals, more vitamins and minerals for our bodies to recover, and more information about what we’re putting into our bodies and why. Our team (who happens to be predominantly female), realized we could do better for women athletes in need of supplements, and so we did.

Energy + Focus

Energize your day with STAMINA Energy Formula, a pre-workout for women.


  • When should I take a pre-workout for women?

    If you’re using STAMINA Energy Formula before a workout, we recommend taking it about 20-30 minutes before your training begins. That way, your body has enough time to digest the pre-workout, allowing you to feel its energizing effects throughout your session. Did you also know that pre-workouts aren’t just for, well, pre-workout? You can take STAMINA any time throughout the day when you need a boost of energy. What’s more, our energy formula is a great alternative to your morning java — one serving contains about as much caffeine as a cup of coffee.

  • How much caffeine should you have?

    Most of us know (and dread) the jittery effect that too much caffeine can have on our bodies, which is why the Mayo Clinic recommends no more than 400 MG of caffeine per day — about four cups of coffee. However, some people are more sensitive to caffeine than others and may need to adjust their intake accordingly.

  • Will it make me jittery & itchy like other pre-workouts?

    It shouldn't! We formulated this product and the doses to make sure that doesn't happen!

    That feeling you get from other pre-workouts? It's from the high levels of caffeine and Beta-Alanine. Our pre-workout does contain both of these ingredients because they help boost your workout, but we dropped them to a level appropriate for a woman's body.

    If you haven't taken pre-workout powders before, we do suggest starting with a half scoop to allow your body to get used to the supplement and building up from there.

I just started getting back into working out and waking up at 5:30 am or earlier is tough... PRTCL Pre-Workout "STAMINA" has been such a helpful tool in my journey. Thank you so much for such a great-tasting product. Now... I just need to hide it from my husband! He says it tastes and works better than what he was using! lol.

I've Found My New PreWorkout!

LOVE this product! No jitters, no crashes, just pure energy for those early morning workouts. I used to be a big pre-workout in a can person, but since trying this I'm never going back!

Crazy reaction.

I tried this prior to one of my workouts. Immediately had a pins and Needles all over my body and face. It was terrifying. I dont know why this happened but it did so I did not try it again. It taste good though so I still gave it a few stars.

We hate that you still felt the skin tingle after our reformulation. Sometimes this happens to those who are sensitive to caffeine and beta-alanine. While we dropped the doses of both to be for a woman's body, we suggest you use half a scoop in 20 oz of water to help your body get used to the new energy source and take away this feeling and increase little by little every 30 days.
