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™.*

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.

“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.”*

I was concerned that the lime taste might be overbearing in this, but I need not have worried. The taste is perfectly balanced, you get just the right amount of lime flavor with a hint of the crust flavor underneath. I don't know how they layer flavors like that, but this shake is delicious. It mixes very well with just a blender bottle, leaving no grittiness or residue. I don't like any protein shake with water, and this is no exception, but when mixed with milk it is perfectly creamy. The profile boasts many ingredients above and beyond your run of the mill protein shake, for that extra recovery boost. The profile is actually really amazing, and you get a lot of carbs to go with that protein. Win/win if you ask me. The price is a bit high at $4/serving, so that keeps it from becoming a staple in my supplement regimen, but it is a solid, quality product that I will keep my eye on and will very likely be purchasing from time to time. I would recommend this to anyone.

Post Factor is without a doubt in my mind one of the best recovery formulas/supplements out there. With carbs and a healthy amount of protein with minimum fats, it's the perfect supplement to go to after a heavy session to help your body recover/repair. The Key lime pie is DELICIOUS and I could drink it every day. It's a touch of sweet with the distinct taste of key lime without being over bearing. Mix it in with milk for that perfect creamy texture. The only "downside" to the product is the price as it's generally more than most people want to spend but if you want a QUALITY recovery supplement that tastes great, give post factor a try... you don't be disappointed.

[center][color=blue][size=10][b]Final Review[/b][/size][/color] I want to thank the folks at Blue Star for sending me a tub of Post Factor to try out and review. I requested the Chocolate Truffle flavor and then purchased the Key Lime and to get about a months worth of servings. Post Factor is Blue Star Nutraceuticals recovery supplement, it is something I had looked at a few times and had an interest in. Over the last few years I adapted more to eating whole foods after a workout compared to using shakes and after doing a little research and self testing I realized that pre and post workout shakes benefit from protein and carbs. In the past I had used Anabolic Window from Nutrabolics but that product was discontinued a few years ago and after that I never really found another recovery shake that I liked. Knowing that Blue Star is a reputable company I knew at some point I would pick up a container of this to try out. Here is a link to the product in the store - you can read all the tech/science behind the product as I won't get into all of that in this review but I will touch on some of the claims and how I felt the product worked out for me. At 310 calories per serving, Post Factor is giving you 27 grams of protein, 50 grams of carbs, 3 grams of sugar, half a gram of fat, 2 grams of L-Carnitine L-Tartrate, half a gram of Cherry PURE, and 61mg of their XD Delivery Technology Complex. There are also some vitamins and antioxidants in the product. One of the first things I noticed and liked was that the ingredient list was not a mile long, pretty cut and dry which is nice. The additions that are included in the Muscle Recovery Complex and the XD Delivery Technology Complex are nice, seeing the 2g's of LCarn LTart was nice along with the Tart Cherry. I've used a few different LCarn products or supps that have LCarn - a few readings I looked at showed that at 2g's a day, there can be some great benefits to recovery as well as how your body metabolizes fat. There is a bit of different writings on the tart cherry but Blue Star claims that between the Tart Cherry and LCarnLTart recovery is drastically better. I don't know that I could agree with 370% (science) but I do believe the product aided and assisted with recovery. I was able to get in more sessions and get more out of my sessions I felt. Initially I had been on a 4 day split, after using the product for a week or so I started pushing in some extra work with the intent of seeing how the body reacted and was capable of pushing out. On the regular 4 day split I can say recovery differences were noticeable and while adding in 2-3 days at times, I was able to get the extra work in and push out some good sessions on back to back days or working some body parts multiple times in a week without rest days in between. While smell isn't the most important thing I think it is worth touching on. Having a wine background and enjoying wine you learn that if something doesn't smell right you may not want to take the next step in tasting it. With this product both flavors had nice aromas, no issues there. The taste, I was surprised with the flavoring, chocolate being as common of a flavor as it is, I tend to either like or dislike them. The ones I like tend to be pretty common in taste, this one was not only very good and did have a different taste to it. The flavor was not over powering and seemed to linger on the palate more than most. I can't really compare the Key Lime to other supps as this was the first Key Lime supp I've had but it was outstanding as well. I do enjoy Key Lime Greek Yogurt and while this did not taste exactly like that it was very pleasing. This was probably the only area where the product gave me some occasional issues. I've had proteins that have mixed a lot worse but this did take a lot of shaking to really get it dissolved. I didn't have major clumping but after the initial shakes I'd normally have quite a bit of smaller clumps. I used the same shaker most the time to see if it was a consistent issue or not, it was one of the shakers with the metal ball inside. Normally it would take about 2-4 rounds of some good shaking to get most the product dissolved. Below are some pictures you can see some of the smaller clumps I'm talking about. Keep mind, this was not a major issue and I've seen much worse, but this as probably the only negative I found with this product. There was a noticeable amount of foam when shaking initially but it does settle fairly quick. Here at the product sells for $56.99 a tub, you are getting 14 servings per tub so it comes out to $4.07 a serving, while it would be nice to see this in the low to mid $3 dollar range per serving I would purchase at the current price considering the quality ingredients you are getting and knowing Blue Star is putting out quality products. Its nice to be able to get a good post shake out of one product also, mixing multiple things PWO, Intra

This is easily one of the best recovery formulas on the market. A full dose of protein, post workout carbs, and a number of adaptogens to promote recovery in clinical doses. Yes, it is pricey, but there is nothing in the market like Post Factor. The Key Lime Pie is delicious. It's sweet without being overly sweet and the texture is fantastic.

Aug 01, 2017

Perhaps the best overall recovery supplement that I've had the privilege of using. Post-Factor has definitely allowed me to recover faster after my workouts and feel completed recharged and ready to go the following day. 50 grams of carbs, 27 grams of whey isolate.....I couldn't ask for a better recovery combo than that. Plus L-Carnitine L-Tartrate and Tart Cherry and you've got yourself the ultimate recovery formula.

Key Lime Pie! Need I say more! Taste: If you like Key Lime Pie you will love this post workout shake! This is awesome! You get the tartness of the Key Lime along with the sweetness but not too sweet along with the flavor of the graham cracker crust! I don't know how they get all the flavors in there but just imagine taking a slice of Key Lime Pie and adding a little protein to it in a blender with some milk.... MMMmmmm! So Good!!!!! Mixability: This stuff mixes up great whether in a blender or in a shaker bottle. I had no clumps or settling. It will produce some foam but to me that just made it better. Kind of like the whipped topping on top of a pie! Ingredients: I'm not going to list them here because they are already listed at the top of the page! They are QUALITY! I love the transparency of the label. No proprietary blends! Good quality ingredients which shows in the cost. Price: I am not a fan of the price at $56.99 that's $4.07 a serving, but I understand that with quality comes cost. If you want a quality product then you must be willing to pay for it. You get what you pay for! Overall: I give this product a 10 out of 10 even at the price point because of what you get for it. A great recovery shake that gives all the right nutrients to replenish what your body needs after that hard grueling workout! Give Blue Star Nutraceuticals Post-Factor a try today!

Currently I am following Lyle McDonald's UD2.0 regimen where its several days of PSMF macros topped with depletion/tension workouts (hell). Followed by a structured massive 1.5 day carb up and a power full body lift on Saturday. During this carb up I am aiming between 1100-1200gs of carbs (fun stuff). By the end of it I dread the thought of pasta and sweet potatoes lol. This product fits perfectly into that time frame and allows me to get the right carbs at the right time (even though nutrient timing is mostly irrelevant, I still try to follow the protocol to a T) Ingredients : 50g C / 27g P / .5g F - your not gonna find more bang for your buck macro wise if your looking for quality proteins and carbs without the unnecessary fat. Going from a ketogenic state to a full on carb load, this is the first thing I consumed after last night's tension workout when I was fully glycogen depleted. I could almost feel it going straight to my muscles and my skin feeling tighter and my body more full (not bloated). It's easy to notice how effective this was working due to being completely flat and depleted from high rep workouts and hard cut macros during the week. This is exactly the fast acting carbs I was looking for in a product. Before I was using a combo of dextrose, oats, protein powder, fairlife milk etc.. this one product replaced them all! It was glorious and efficient. 10/10 Flavor : I chose the key lime flavor and boy I am glad I did. Each sip reminded me of a beautiful summer day by the pool or a cool summer night on the deck of a cruise crushing key lime pie (some of my fondest memories of key lime pie - I used about 15oz of water which was a good amount. On top of the flavor, I sipped it slowly to enjoy which was awesome, other carb-y products I have had to choke back and get them down just because you know .. macros. This also led to me being comfortably full and sweet tooth cured so by the time I got home I was not ravenous for sugary junk. I could focus on pasta, sweet potatoes, and starchy goodness. This flavor is refreshing, smooth, and a good change of pace from the countless chocolate, CnC, vanilla etc flavors of protein powders I have. 10/10 Mix-ability - Few good shakes in a blender bottle with some ice cubes and we were good to roll. Like most high volume (g) carb-y products I have experienced, it was a little foamy. Nothing to write home about. Can't fault the product at all here 9/10 Price - For the purpose of my individual needs and frequency I would use this product, price is not an issue to me for something of this quality and efficiency. At 56.99 someone who is using it every day and only getting 14 servings it might be an issue. This is the only real downfall. 7/10 Overall - I am very pleased I chose this product out of the Blue Star line to try. It fits perfectly into my plan, the taste is A++++++, the macros are on point, it pretty much takes the spot of my old carb up drink that needed 4+ ingredients all in one scoop! Highly recommend. 9/10

WOWOWOWOWOWOWOWOWOWOW! This is one amazing protein. The flavor is exactly like a key lime pie. It makes me want to try out the blueberry pomegranate too because at this point, I don't think Blue Star can do anything wrong.

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.

Feb 08, 2017

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!

Feb 05, 2017

**** Post Factor Key Lemon Pie tastes amazing!!! Def nailed that flavor! Idk about you but when I have dessert I like to enjoy it, I take a bite and let it melt in my mouth, before downing it and Post Factor got that same taste as the actual dessert pie. Does not amaze or surprise me as the company always has put out great tasting proteins! A lot of people mention the scoop size, well yeah it does have 50g of carbs along with the protein and the rest of the goods, it can't be the same size of the other protein powders out there, if it was, you know something wouldn't be right... but that's not what the guys behind this company are like. I had no problems mixing this with water in my shaker, does foam somewhat but that has never been a problem for me. I think the profile is fantastic as well, personally, i can't say if it helped me recover after the gym because the taste is so **** good that every time I was having my shake I was enjoying the flavor so much that I never really took the time to notice lol. It's not cheap but you do get what you pay for and that's quality!

Feb 04, 2017

This tasted unreal! Mad props to the flavour, mixes really well with water and milk. 85g scoops with this, so you have to be willing to drink a pretty tall glass. It better taste right... and it does. Overall just a great feel to have after a lift when you know you're getting pact with goodies, nice clean carbs, 27g of protein, solid recovery process right there. Plus they throw their blend of recovery and delivery technology complex is the mix. Pricey, but you know you're going to get some of the best quality in supplements.
