Alright, this is going to be my personal unbiased review on the new product BLOX by BPI Sports. This product is touted as the next generation of intra-workout because supposedly silk amino acids are better than regular amino acids. I chose to personally buy, try, and review this product because of the marketing hype, exorbitant prices, and inconsistent reviews on this product thusfar.
30 Servings 5g/serving
SAA Sequenced Proteins 3,960mg
(Alanine, Glycine, Serine, Valine, Threonine)
Other Ingredients (Citric Acid, Taurine, Silica, Flavors, Sucralose, ect)
A recent animal study, found that when exercising mice were given three different doses of silk amino acids for 44 days, the mice experienced: Improved exercise performance.
SAA fed mice exercised more than twice as long as mice not fed SAAs (28 minutes vs 13 minutes)
In terms of absolute improvement in exercise performance, SAAs produced improvements that were six times greater than that seen with just exercise (18 minute increase compared to 3 minute increase).
Eliminated the increase in blood lactate levels (which were significantly increased with just exercise)
Eliminated the increase in muscle oxidation (which was also significantly increased with just exercise)
Maintained blood glucose levels (vs being significantly lowered in exercising mice)
Increased muscle glycogen and liver glycogen (compared to exercise alone)
Increased testosterone levels (64% increase vs 36% reduction in exercise group; in absolute terms, blood testosterone levels that were 2.6 times higher in SAAs group compared to exercise group)
Reduced cortisol (140% increase in cortisol in exercising group while no significant increase was seen when SAAs were given)
Increased anabolic ratio (4-fold higher anabolic ratio; ie, the testosterone to cortisol ratio compared to mice not receiving any)
Increased muscle size (16% increase with high-dose)
All these claimes were gleaned from wikipedia, there was a workes cited to the actual study. The three doses that they gave the mice were 50, 160, and 500mg/kg. That would translate between 5-50 GRAMS for someone my size (approx 100kg). So, according to the study, if we reacted proportionatly with mice, we would need approx 12-15 scoops of BLOX per day for results mimicking the upper level dosages in mice.You can claim all you want, but if I’m really going to have to take 50 grams for proportionate results I want to know that ahead of time.
Now for my ratings:
In order to gauge comparable effectiveness, I took a similar amount of BLOX as I would any other amino acid intra, which is approx 3 scoops (15 grams) per workout. Ok, so not quite accurate as 3,960mg/scoop makes 3 scoops what? 11.8grams? Anyway, I dosed it that way after switching off of my normal intra amino. During the entire time I took this, I did not notice any increase in recovery whatsoever. I was, in fact, a lot more sore, but I also switched my routine to a more demanding set toward the end and I added more in to make up for the recovery gap.
Overall, my summary for effectiveness is that it didn’t stand out to me as the “next generation in recovery”. Did it work? Yes, as opposed to nothing it worked, but I don’t think it worked any better than your run-of-the-mill intraworkout.
I tried out the watermelon flavor and it was pretty good. It was not overly sweet or an overpowering flavor, it was a good flavor to drink as an intra, when in my opinion, you would rather feel like you are drinking water than a soda or something thick tasting.
First off, dosing. There are 30 scoops per tub, but needing at minimum 3 scoops per workout, the tub will only last 10 workouts. The price of this product has come down a little bit, but even now, its about 30 bucks a tub. That makes each necessary dose cost $3 bucks a day which is very steep. Amino acid powder is very cheap, Modern BCAA sells 35 actual servings (10g BCAA’s) for 29.99. That’s less than $1 a serving!
I think I am very generous giving this product an overall 5 rating. Why? First off, their own research on silk amino’s put the effective dose at between 5-50 grams per day. I did not go through the actual paper to find out which claims went with which doses, but I think it’s safe to assume that the bigger claims went hand in hand with the huge doses. Do you want to take a tub and a half of BLOX a day for results?
Ok, but it works ok right? Yeah sure, in comparison to the same amount of BCAA’s its fine, but it also costs THREE TIMES AS MUCH. Not only three times as much as and BCAA product, but three times as much as USP’s Modern BCAA, which is one of the highest rated BCAA products available.
Overall, this is not an outstanding product at all, and it is not worth the exorbatant price that they offer it for. Not only did I not notice commendable results, but their own research data does not back up their claims.
- Not Outstanding
- Too Expensive
