Regan Grimes Recommended Supplements

Everyday we receive thousands of questions from loyal consumers inquiring about our line of supplements as well as the healthy lifestyles of our featured athletes.

One of the most frequently asked questions is what does Regan Grimes’ supplement stack look like?

Well, you’re in luck as we reveal precisely what Primeval Labs supplements Regan Grimes uses on a daily basis.

Regan Grimes' Pre WOrkout

Mega Pre is a delicious-tasting, stim-free pump pre workout formulated to support athletic performance, focus, and stamina.

Mega Pre White 

Mega Pre White is a stimulant-free pump pre workout supplement designed all around enhancing blood flow, performance, and pumps.

Regan takes two scoops of Mega Pre white prior to every training session, 

Every serving of Mega Pre contains quality doses of research-backed ingredients, such as L-Citrulline, Betaine Anhydrous, elevATP, and VasoDrive-AP.

The reason we chose to no include stimulants in Mega Pre is three-fold:

  • Certain stimulants can cause blood vessels to constrict (vasoconstriction), which limits blood flow, nutrient delivery, and pumps
  • Stimulant blends are often the cheapest component to a pre workout, and we’d rather invest those dollars into ergogenics and nootropics like elevATP, Huperzine, and VasoDrive-AP.
  • Sleep is vital to recovery, performance, and growth. Consuming stimulants late in the day can disrupt sleep. We formulated Mega Pre so that it can be taken anytime of day (morning, noon, and night) for a great training session without having to worry about jitters, crashes, or disrupted sleep.

Intracell 7

As you’ve seen for yourself, Regan likes to train hard using heavy weight and high reps. To help him sustain a high level of performance throughout is high volume workouts, he uses Intracell 7 Black.

Intracell 7 Black was created to supply hard-training athletes with the essential nutrients they need to go the distance in their workouts, be it powerlifting, bodybuilding, CrossFit or field sports.

Intracell 7 Black contains a synergistic matrix of fast-digesting, performance-boosting carbohydrates such as Cluster Dextrin and Carb10 alongside blood flow enhancers and hydration agents. We’ve also included a full complement of essential amino acids to support muscle protein synthesis and resist muscle breakdown during training and competition.


After a tough workout, your muscles are screaming for nutrients, protein in particular.

Regan’s post workout meal of choice is Primeval Labs best-tasting protein powder - ISOLIT.

ISOLIT supplies 25 grams of high-quality protein from 100% cold-processed whey protein isolate.

Whey protein isolate is an incredibly clean protein source that’s low in carbohydrates, lactose, and fat while retaining high amounts of beneficial fractions naturally occurring in whey concentrate.

ISOLIT mixes easily, tastes delicious, and provides skeletal muscle with a fast-digesting, highly bioavailable source of protein. Best of all, ISOLIT comes in SEVEN flavors, so there’s sure to be a flavor that suits even the most discerning palate! 


Amino acids are the "building blocks" of protein, and amino acid supplements are some of the most popular products on the market.

EAA Max is a delicious-tasting essential amino acid supplement that supplies all nine essential amino acids (EAAs) required for protein synthesis, including 5g 2:1:1 BCAA, as well as valuable electrolytes from Pink Himalayan salt to support hydration.

Regan likes to use EAA Max as a between meal snack to keep a steady supply of essential amino acids pumping into his muscles during the day to support muscle recovery and growth. 

EAA Max can also serve as a low-carb, low-calorie intra workout for those carb conscious athletes out there who want to take advantage of intra workout nutrition but don’t want to consume a lot of carbs during training.

Glory MV

The final component to Regan’s supplement stack is one that many of you likely have -- a multivitamin/multimineral supplement.

Glory MV is our take on the popular dietary supplement that supplies over 20 essential vitamins and minerals to support your active lifestyle.

Multivitamins help “fill in the gaps” in your diet that may develop as a result of intense exercise. Deficiencies in these essential micronutrients can impair performance, recovery, and growth.

We developed Glory MV to complement a healthy diet and help prevent any gaps from developing in your micronutrient intake.
