STAMINA Energy & Focus 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 support muscle health and slow caffeine absorption for sustained energy that lasts all day. Each serving contains about as much caffeine as a cup of coffee, so there are no crazy jitters here — just the perfect pick-me-up for women in motion.* 


  • FORMULATED BY WOMEN, FOR WOMEN: PRTCL Products were created for women, by women and are formulated specifically for a women’s body and her nutritional needs based on actual scientific research.
  • NO JITTERS! LOW-CAFFEINE LEVELS: to be the same as a cup of coffee (100 mg) vs. the overload (300mg) in a men's pre-workout. 
  • NATURAL ENERGY SOURCES: We added vitamin B6 and B12 to give a natural source of energy that sustains us longer.
  • LITTLE TO NO SKIN TINGLES: We dropped the beta-alanine (1.5g) content to get the benefits, but not the side effects.
  • GET FOCUSED: L-theanine and l-tyrosine (500mg) are two amino acids our bodies need to help you focus on the task at hand. 
  • GLUTEN FREE: Safe for those with celiac disease and gluten allergies.
  • INFORMED SPORTS-ACCREDITED: All PRTCL Products’ Supplements have been third party, Informed Sports-tested and certified to be free of a broad range of substances banned by the World Anti-Doping Agency (WADA).

What’s inside our energy supplements for women?

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 and B12, which provide sustained energy for your day. Plus, we’ve supplemented this energy supplement for women with electrolytes for hydration and amino acids for muscle health–leaving you energized, invigorated, and ready to run the world. 

Get to know our ingredients

Thiamin: Also known as vitamin B1, thiamin helps the body convert carbohydrates into energy. Additionally, the body uses thiamin to create adenosine triphosphate (ATP), a molecule that transports energy within your cells.

Vitamins B6 and B12: These vitamins work to give you an energy boost — vitamin B6, also known as pyridoxine, contributes to metabolism and the creation of red blood cells, while B12, or cobalamin, supports nerve cell function, red blood cell formation, and DNA synthesis.  

Amino Acids: Not only do these amino acids support muscle health, but they also help slow down caffeine absorption for sustained, all-day energy.

Green Tea Extract: A concentrated form of green tea, this extract contains immune-boosting antioxidants as well as caffeine for a natural boost of energy. 

Phosphorus: This mineral is the second most abundant mineral in the body after calcium, and is required for vital bodily functions like filtering waste and repairing tissue and cells.

Potassium: This electrolyte is known to help with muscle cramping — especially during long workouts — because it helps regulate blood pressure and water retention.  

Sodium: We lose a lot of sodium through our sweat when working out, so it’s important to replenish this mineral as it regulates the proper balance of water and minerals as well as muscle contractions.

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 - Strengthen + Nourish: Whey protein powder anytime or in your favorite recipes.

02 | STAMINA - Energy + Focus : An alternative to your morning coffee to energize and hydrate.

03 | REPAIR - Strength + Recovery: To rebuild and recover as you wind down at night.*

04 | SUPPORT - Immunity + Hydration: A boost of vitamins for healthy immune function and hydration.

Girl, you got this.

At PRTCL, we know that women need more from their energy supplements — more protein, 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 in need of energy supplements, and so we did.

Energy + Focus

Energize Your Day With STAMINA Energy + Focus Formula


  • When should you take the STAMINA Energy + Focus Formula for women?

    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.

    If you’re using STAMINA Energy + Focus 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. 

  • 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 energy supplements? It's from the high levels of caffeine and Beta-Alanine. Our energy powder for women does contain both of these ingredients because they help boost your energy and focus, but we dropped them to a level appropriate for a woman's body.

    If you haven't taken energy 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.
