13 Best Supplements to Gain Muscle 

Did you know there are supplements that are key to help you gain muscle mass and help you become the healthiest you’ve ever been? 

There are a lot of different supplements out there, and they all may have different uses, but there are 13 that play key roles in your muscle building goals. 

If you’re interested in adding supplements into your daily routine, then you’re going to want to add the best of the best. Here’s our list of the 13 best supplements to gain muscle:

  1. Creatine

Creatine Monohydrate is a naturally occurring metabolite found in muscle tissue. It helps rapidly re-synthesize ATP, the ultimate form of energy used by muscle cells to generate force (muscle contraction). Creatine has been clinically shown to improve muscle strength, torque and performance. GAT Creatine helps maximize muscle size and power and enhance recovery. 

  1. BCAAs

BCAAs or branched-chain amino acids are 3 of the nine essential amino acids (leucine, isoleucine and valine), which are key to the health of your body. “Branched-chain” is the chemical structure of BCAAs, which support lean muscle-building and recovery. GAT Sport BCAAs include co-factors to support your metabolism, improve endurance, and boost your body’s immune system. 

  1. Protein 

GAT Sport Plant Protein is an all-natural protein powder blend that provides 21 grams of protein from five plant sources. Plant protein offers a unique combination of taste, potency, and digestibility and supplies a 20g amino acid profile of pea protein isolate, organic brown rice protein concentrate, quinoa sprout powder, coconut pulp powder, and artichoke protein. 

GAT Sport Plant Protein delivers the best combination for muscle growth and recovery. With each serving providing all the same amino acids found in whey protein.

  1. EAAs

L-Carnitine helps the body produce energy providing support for endurance exercise (aerobic) and during recovery from high-intensity activities such as weightlifting and sprinting (anaerobic).

  1. CLA 1250

Controlled scientific studies have suggested that supplementing with Conjugated Linoleic Acid (CLA) supports maintaining lean muscle while reducing fat. This natural supplement works by stimulating your metabolism. With proper exercise and a healthy diet, supplementing with CLA supports fat loss and muscle growth. 


GAT Beta-Alanine supplementation has been shown to increase muscle carnosine levels, which lead to improved physical performance during high-intensity exercise. GAT Beta-Alanine can help you knock out more reps and power through your workouts. 

  1. Caffeine

GAT Caffeine Tablets deliver a 200 mg surge of caffeine any time you need to quickly jump start your mental and physical performance in order to maximize your training. Caffeine triggers a range of performance-specific benefits including improved focus, elevated alertness, faster reaction time, reduced fatigue and increased endurance.


Agmatine, a by-product of Arginine, is a more direct way to improve nitric oxide synthesis, which has been shown to enhance muscle pumps and support recovery from intense workouts. Agmatine also helps regulate hormone release and is beneficial for healthy neurotransmitter activity and insulin response.


L-Arginine is a conditionally essential amino acid and helps your body produce Nitric Oxide, which supports muscle development and recovery. L-Arginine helps increase blood flow to the muscles making it an excellent supplement for high-performance athletes like bodybuilders. 

  1. Whey Protein

Each scoop of GAT Whey Protein is packed with 25g of fast-acting 100% premium whey protein that gets straight to work on your muscles. Each scoop contains over 5 grams of BCAAs from protein.
