Product Overview


Refuel. Recover. Rebuild
Blue Star Nutraceuticals Post-Factor bottle

Support Power*

Enhance Performance*

Support Exercise Recovery*

Athlete working out in the gym
A strong finish means
a stronger start.

Gritty, bar-bending workouts are what separate the men from the boys. They bend and break your muscles into a catabolic state, depleting your energy reserves.

And as a result, your muscles are now stimulated. Ready to grow bigger and return stronger - but only if they have the nourishment they need.

Everything your muscles crave - In one scoop.

Post-Factor™ is much more than a protein shake. It contains carbohydrate and antioxidants (Vitamins C and E), and is a fast-acting protein shake designed specifically to be taken after your next grueling workout.* Oh yeah, it also comes with our trademarked XD Delivery Technology™.*

Broken down for you.

The building blocks of new muscle are amino acids. Protein has them. Post-Factor has it. See the pattern here?

Each Post-Factor serving contains 27 grams of the most advanced whey protein ever developed — hydrolyzed whey protein isolate.* Hydrolyzing whey protein isolates, breaks the larger proteins into smaller pieces. These ultra-pure whey isolates are thought to be absorbed by your body much faster than non-hydrolyzed isolates, allowing your muscles to begin recovery significantly sooner.*

Man stretching.
Support Recovery - Antioxidants.*

Each serving of Post-Factor contains more than 100% of the recommended daily intake of Vitamins C & E; two powerful antioxidants that help with exercise recovery.*

Your after-workout dessert.

So what exactly does a groundbreaking rapid-recovery shake taste like? Well, when the flavor team has over 25 years of experience, the answer is "pretty darn good."

Reward your post-workout taste buds with Key Lime Pie, Blueberry Pomegranate, and Chocolate Truffle. Your mouth, and your muscles will thank you for it.

“The couple of hours immediately post-exercise are when muscles are the most sensitive for growth. However, exercise alone in a fasted state leaves your muscles in constant catabolism until your next meal. Your post-exercise meal is a critical component to how your muscles will respond to the exercise. Post-Factor™ takes all the guess work out and provides only the best ingredients to maximize your muscle growth and recovery.”*

This post-workout carb/protein/recovery drink is simply amazing. The profile is superb, and the taste is AMAZINGGGGGG. The kinda drink that makes you sad to take off days because you don't get to drink it that day. I was at a point with my routine that every day, I was wondering if I'd be recovered enough for the next days workout, and sometimes still worked out sore. I'm at a calorie deficit so recovery has been tougher for me, but even after lowering calories from a 250 deficit to a 500 cal deficit, I have observed greater recovery where I am no longer sore for my workouts. It could just be a giant coincidence, but experience in the matter leads me to believe this product really actually helped with recovery. The scooper is HYUGE lol never seen any that size before. The shake foams up quite a lot, which I'm not used to, but this product is so great that this aspect is very easily forgiven and forgotten. YUM

First and foremost ... the taste is amazing!! I don't usually write reviews but I had to for this product. Probably one of the best tasting supplements I have ever tried period. It also helps that this product actually works. The 27g of protein and 50g healthy carbs are exactly what I need after one of my sessions. There is a lot of foam after mixing for some reason but I don't mind, and usually I will shake it up, go grab a quick shower and come back. By then almost all the foam has dissipated, chug and go on about your day. The scoop is HUGE for such a small container, but this is only a problem because I have very much larger than average hands. It's just hard to get my hands in the container with a full scoop and transfer it to my storage container for the day without powder going EVERYWHERE. Not a big deal unless I'm already dressed for work as it's interesting to try to explain the bits of powder that is on the sleeves of your suit jacket LOL. But I've noticed decreased DOMS and my strength has not decreased nearly as much as I am used to by this stage in my cut. I have been using Bluestar products for a while now. If you are familiar with their products you know they only make quality products and this one does not disappoint.

This simplifies my post-workout nutrition immensely. It's hard to keep fats at a bare minimum and have something that is enjoyable. Post-Factor hits on all accounts. I use this on my heavier lifting days and dose it at 1.5 scoops to hit my target of 75g carbs/37-40g protein. Great ~2:1 ratio, and some nice recovery additions in there as well (tart cherry, L-Carn). I found that mixing it in a blender and with 2/3 the suggested amount of water work best. I've also tried 1 scoop mixed with plain greek yogurt and was amazing. My only knocks on this product is that due to the fast digesting carbs, it is a fine powder that can blow everywhere if not careful; I would like to see a 1/2 serving scoop, the one provided is so large that it is hard to control transfer into a regular shaker; and either have more servings per container or a price that I could get 2 at a time.

Post Factor is not a regular protein powder. It is intended to be a post workout recovery shake. One serving includes 27g of hydrolyzed whey protein isolate, 50g of high quality carbs, more than 100% of the RDA of vitamins C and E, LCLT, and CherryPure (tart cherry) to help you recover from your toughest workouts. The label says to mix one scoop with 12 ounces of water. I mixed my first serving with 12 ounces of water and a few ice cubes and it mixed a little too thin for me. The flavor was good, but maybe a little watered down. Next time, I mixed it with 8 ounces of water and a bunch of ice cubes. Better. The flavor is a bit sweeter than I expected from blueberry pomegranate (I thought it might be a little more tart), but still very good. Then I decided to try it with milk. Even just 2 ounces of milk and the remaining amount water and it tastes like a rich smoothie. Delicious! Same for key lime pie. The hype is real, this stuff tastes great! The serving size is large and it is filling but it doesn't sit "heavy" in my stomach, either.This is a product that really comes in handy when you don't have time for a real food meal after a tough workout. It will be a big help for me to have this on the shelf when I get home from a 40, 50 or 60 mile bike ride and can't sit down to eat before I have to leave again.

Very effective product with amazing taste! Can't ask for much more from a post workout product. I'm a huge Key Lime Pie fan and Blue Star nailed this flavor. Very smooth and refreshing after a hard workout. Noticeable improvement in recovery. Highly recommended!
