The Truth About Mass Gainers

Most mass gainers make you fat, not big. Here’s how to choose one that actually helps you build lean, clean muscle.

Hi again guys,

Food should always be the foundation of a successful bulk. Real meals, real digestion, real nutrients — that’s the backbone of sustainable weight gain.

But the moment someone decides to start a bulk, what do they do?
They run straight to mass gainers.

So let’s break them down properly — what they are, why they seem helpful, why most of them fail, and how to actually use them effectively.

💥 What Are Mass Gainers?

Mass gainers are some of the most popular supplements for putting on weight. Think of them as hyper-caloric protein shakes — usually a blend of:

  • whey protein

  • fast-absorbing carbs

  • cheap oils or fats

  • artificial flavors

  • thickeners and fillers

It would not be an exaggeration to say that 90% of mass gainers on the market are trash.
They’re high-calorie, yes — but usually in the worst possible way.

And while making your own is ideal, what if you didn’t have to?
Let’s first understand the “why.”

🧠 Why Do People Use Mass Gainers?

A few reasons come up over and over:

  • Liquid calories are easier to consume

  • They’re fast to prepare

  • Easy to drink on the go

  • They create a psychological “I’m bulking” feeling

  • They help people hit a calorie surplus

Do they work?
Yes — if “work” simply means gaining weight.

But weight ≠ muscle.
Most commercial gainers push you into a sloppy surplus, leading to:

  • excess fat gain

  • blood sugar issues

  • poor digestion

  • inflammation

  • worse training performance

So yes, they work — but not cleanly, not intelligently, and not sustainably.

❌ What Most People Get Wrong

The biggest mistake?
Using mass gainers at the wrong time.

People drink them:

  • for breakfast

  • as a random snack

  • before bed

  • during work breaks

All of these are pointless. They spike calories when you don’t need them and encourage fat storage.

✅ When mass gainers actually matter:

Peri-workout.

This includes:

  • Pre-workout:
    If you haven’t eaten in the last 2–3 hours

  • Post-workout:
    When glycogen is low and cortisol is high

  • Intra-workout:
    If you’ve already mastered pre and post nutrition

During these windows, your body is primed to:

  • shuttle carbs into muscle

  • spike insulin at the right time

  • drop cortisol

  • accelerate recovery

  • build lean mass instead of fat

Outside of these windows?
They’re just sugar bombs.

🔍 What to Look For in a Mass Gainer

With hundreds on the market, people usually pick:

  • the most popular

  • the highest calorie

  • or the best tasting one

In reality, those are typically the worst.

Example of a problematic one:

Serious Mass by Optimum Nutrition

  • 254 g carbs

  • 1000+ calories

  • 50 g protein

  • artificial flavors + sweeteners

Unless you train like a bricklayer and burn calories all day, this is a fat gainer, not a mass gainer.

⭐ What I Recommend Instead

TRUE Nutrition — Post Workout Blend

This is what a mass gainer should look like.

Why it works:

  • Clean ingredients

  • High-quality protein

  • Optimal carb:protein ratio

  • Creatine included

  • Easy to digest

  • Designed specifically for peri-workout

Macros per serving:

  • 28.6 g protein

  • 33.5 g carbs

  • 2.5 g creatine

Do one serving pre-workout, one post-workout, and you’re set.

Mix with skim milk or filtered water to keep fats under 1 g and digestion smooth.

This is a clean gainer — not an insulin rollercoaster.
