Reviews – The Best Weight Gain Pills

Optimum Nutrition Micronized Creatine Monohydrate Capsules – Best Overall

Creatine has been extensively researched and proven to be effective ever since it was released in the early 90s.

For some, the powder is too gritty and the taste is poor. Capsules are a convenient way to go for users that want to use creatine but don’t want the powder.

Optimum Nutrition Micronized Creatine Capsules provides 2.5g of the proven monohydrate form. This is per a two capsule serving. Two servings at divided times provide the standard 5g dose.

You can take creatine whenever you want during the day. The directions suggest taking creatine with a meal.

For best results, take them with a high carbohydrate meal for better absorption.

Creatine acts as a cell-volumizer, and improves training endurance. It also increases strength, and stimulates muscle growth. 

This is the best overall weight gain pill.

PROS

  • Only 4 Capsules Per Day Suggested Serving
  • 2.5g Creatine Per 2 Capsules
  • Tested 100% Pure

CONS

  • Expensive Compared To Their Powdered Creatine

Buying Guide – How To Choose The Best Weight Gain Pills?

What Are Weight Gain Pills?

At first glance, you might think “weight gain” pills are like those high-calorie weight gainers. Or perhaps pills that stimulate your appetite so you eat more. What we mean is muscular weight gain.

So, we’re talking about natural muscle builders that come in pill form. These pills are designed to help you pack on pounds of lean muscle.

The Best Weight Gain Ingredients

BCAAs

BCAAs – Protein synthesis has become known as a direct key to muscle growth. Of the three BCAAs, l-leucine is the most effective. They are commonly found in several formula types across numerous sports nutrition categories. They can also be used by themselves. Beyond protein synthesis, they also support recovery and help prevent muscle protein breakdown. One of the best ways to use BCAA pills is to take them with your protein powder.  (1)

Creatine

What can be said about creatine? It’s the most researched supplement of all. It’s been consistently proven to be effective. Creatine causes a cell volume or pumped effect by pulling water into the muscle cells. It’s also involved in ATP production, and it supports strength increases.  (2,3)

Epicatechin

This is known as a flavonoid. It occurs naturally in green tea and dark chocolate. Epicatechin stimulates muscle growth and increases the production of nitric oxide. One theory on how it may stimulate weight gain is by myostatin inhibition. This is a form of protein that controls how much muscular weight you can gain. (4)

Laxogenin

This is a plant steroid that activates protein synthesis and increases strength. (5)

HMB is derived from the BCAA l-leucine. It supports protein synthesis and promotes recovery. Vitamin D3 supports the functions of HMB.

(6)

Nitric Oxide Booster

NO boosters stimulate the production of nitric oxide in the body. This promotes good pumps, and increases nutrient delivery. Ingredients include citrulline, arginine, agmatine sulfate, and nitrosigine. They can be in any combination or be stand-alone products. (7)

Testosterone Boosters

Test boosters include ingredients like boron, magnesium, zinc, boron, d-aspartic acid, and tribukus. to name a few. This type of weight gain pill is especially good for older users. This is because natural levels start to decline as soon as the early 20s. (8)

GDAs

Glucose Disposal Agents work by manipulating insulin to drive excess carbs into the muscles.  Carbs are stored as energy by the body. They also pull water into the muscles, thereby increasing muscle cell volume.  (9)

Phosphatidic Acid

This is an ingredient that helps activate protein synthesis.  (10)

Arachidonic Acid

This ingredient is an omega-6 fatty acid that supports protein synthesis. This compound is naturally stored in the muscles. Intense training reduces levels, which can impair protein metabolism.

PEAKO2

This patented compound is a blend of 6 mushrooms that act as an adaptogen. This means it helps the body adapt to physical stress, such as intense training. It also helps increase endurance and power, which helps users get more from your workouts.

elevATP

This compound is a combination of peat and apple polyphenols that supports endurance, power and strength.

What To Consider When Buying Weight Gain Pills

If your goal is to add as much muscular weight as you can, you’ll want to begin by eating a high protein, moderate carb, moderate fat diet. Your training program should be designed to help you build muscle.

For example, a program of compound exercises, progressively heavier weight, and reps in the 6-8 range are a good place to start.

Make sure your protein intake is high and consistent. Use a protein powder, but complement that with BCAA pills. One of the keys to your goal of weight gain is to maintain an anabolic, or positive, environment in the body. This simply means your body is in an ideal state to build muscle.

BCAAs should be a foundational product, and to be honest, creatine should be as well.  From here, you can add any of the products you see in our guide.

How To Use Weight Gain Pills

No matter which weight gain pill you choose, you should read and follow all label directions. Read all available information and take exactly as directed.

Conclusion

There’s quite a few good choices when it comes to weight gain pills.

Optimum Nutrition Micronized Creatine Monohydrate Capsules are the best overall. Creatine has been the standard bearer when it comes to products that are well-researched and considered effective.

If you don’t want to use creatine, MuscleTech Platinum BCAA Pill are the best of this type in pill form. BCAAs are well known for their impact on protein synthesis.
