BLACKSTONE LABS BCAA RESURGENCE BCAA + CAFFEINE
When your primary concern is building muscle, there’s a few things you need to focus on each day -- eating ample calories, training intensely by following the principles of progressive overload, and getting enough rest. But sometimes that’s not enough. Sometimes your body is missing those key nutrients it needs throughout the day to repair, replenish and rebuild your mind and muscles.
L-Leucine (2.5g) Dubbed the “king” of all amino acids, Leucine is one of the three branched-chain amino acids, along with Isoleucine and Valine, that play a key role in muscle growth. Leucine is the primary stimulator of muscle protein synthesis by activating the mTOR pathway which flips the switch in your body to build muscle.
Iso-Leucine (1.25g) Another one of the BCAAs that can stimulate muscle protein synthesis, but to a lesser extent than leucine. However, isoleucine does play a significant role in glucose uptake and utilization during exercise, resulting in greater energy production and performance. Isoleucine may also play a role in fat loss, as some research indicates the amino acid inhibits fat storage and increases fat burning.
L-Valine (1.25g) The third BCAA, Valine supports greater endurance and reduced fatigue while training. Valine competes with tryptophan (another amino acid) for uptake into the brain (and wins!), leading to decreased serotonin production. The brain interprets serotonin as an indicator of fatigue, so with less serotonin, you’ll be able to push harder for longer during your lifting sessions.
