Inner Armour is a Connecticut-based brand that targets their supplements toward athletes, particularly football players and bodybuilders. They’ve got a significant amount of mass gainers, fat burners, nitro peakers, and other supplements but we decided to order their branch chain amino acid supplement, which is called “BCAA Peak Leucine Loaded.”

The bottle claims it supports “rapid muscle growth” and “post-workout recovery” and their site adds that it delays post-workout muscle soreness, improve athletic performance, muscular endurance, lifting capacity, and help athletes “achieve and maintain a lean, cut physique.”

Inner Armour BCAA Peak Leucine Loaded Nutrition and Ingredients

This product contains zero calories. One serving weighs 13 grams and delivers 7.2 grams of branch chain amino acids: 6.2 grams of leucine and 500 milligrams each of isoleucine and valine.

The only other active ingredient is 2.5 grams of glutamine. Then there’s just the ingredients used for flavoring: the artificial sweeteners sucralose and acesulfame potassium, citric acid, and natural & artificial blue raspberry flavor.

Inner Armour BCAA Peak Leucine Loaded Beneits and Effectiveness

There aren’t many ingredients to talk about here; it’s a very basic product. It has the three main branch chain amino acids leucine, isoleucine, and valine, which have been linked to improved muscle retention, endurance, and focus during a workout.

Inner Armour BCAA PEAK Ingredients

What’s most unusual about this product is that it’s much higher in leucine than other BCAA supplements, which typically stick to a 2 or 3:1:1 ratio of leucine, isoleucine, and valine. Inner Armour Peak BCAA has a 12:1:1 ratio.

The reasoning given is that leucine is the amino acid that’s most responsible for muscle protein synthesis, so it stands to reason that a BCAA supplement that’s very high in leucine would be better at stimulating muscle growth. That sounds good in theory, but studies have found that for whatever reason, muscle protein synthesis is higher when study participants stuck to a more conventional BCAA ratio than a very high leucine blend.

The only other ingredient is the glutamine. A lot of people see glutamine as a muscle building amino acid, but supplementation doesn’t appear to be that useful with otherwise healthy adults. It’s already the most abundant amino acid in the body and went supplemented, it looks like most of it winds up stored in the gut.

Inner Armour BCAA Peak Leucine Loaded Price

Inner Armour BCAA PEAK Price

If there were a lot of vitamins, citrulline, beta alanine, agmatine, or any other extras, BCAA Peak Leucine Loaded wouldn’t appear that expensive. But for what you get with this one, I think it’s a bit on the pricer side.

Inner Armour BCAA Peak Leucine Loaded Taste

I tried the Blue Raspberry flavor, which was a little unusual. It tasted a lot like a blue raspberry-flavored candy (which is typically just raspberry and a little vanilla), but it wasn’t as sweet as I was expected. To be honest, it tasted a little chalky, and it stuck to the inside of my mouth a bit more than usual.

The Takeaway

I was mixed on Inner Armour’s product. It’s on the pricier side, and it has a lot of leucine (which research is still somewhat inconclusive on as far as how much you really need in a supplement like this), and beyond that, it’s a fairly basic intra-workout supplement.
