Using a potent muscle building stack will significantly speed up the rate at which you pack on size.

Getting your hands on the right combination of supplements can get challenging, especially if you don't know what works and what doesn't.

We found that there's just a small group of products that worked for us by significantly adding lean muscle mass, strength and maximizing our performance.

Keep reading as we're revealing what combination of supplements has worked for us.

The 3 Best Muscle Building Stacks

We've tried many stacks out on the market, but unfortunately, the majority didn't live up to our expectations.

But, there are three combinations that we find to be the best muscle building stacks. We've done a cycle of each and have been impressed by the results.

Take a look at the following three options and consider trying them out to enhance your performance.

#1. Advanced Anabolic Stack


The Advanced Anabolic Stack by Huge Nutrition is the best muscle building stack available right now. If you're looking to take your performance to the next level, this is the stack you're going to want to use.

This stack consists of two products - Sapogenix and Huge Ecdysterone. I've even used them individually, and they're highly effective, but when stacked together, it's just a whole different level of gains.

Here's what I experienced while taking these products:

  • Accelerated lean muscle gains
  • Improved muscle conditioning
  • A massive increase in strength
  • Faster recovery
  • Better pumps during workouts

And what I liked the most is that you can feel the effects extremely fast, within a week. It's because the products contain an advanced absorption technology, meaning they're absorbed more quickly by the body.

The Advanced Anabolic stack will last you four weeks. For maximum results, get yourself two and run it for eight weeks. I gained roughly 10lbs with this muscle building stack and kept most of that.

You won't need post cycle therapy after using this stack since it does not mess with your body's testosterone levels. There are also no other side effects you have to worry about.

It's also worth mentioning that no other company offers these legal steroids or anything that comes close. That's because both the products found in this stack are exclusively available for Huge Nutrition.

#2. Ultimate Mass Stack

Next up, we have the Ultimate Mass Stack by STEEL. It's a combination of three effective and unique products, 1-Andro, 19-Nor-Andro, and 4-Andro.

STEEL is one of the few companies that sell these supplements. Here's what I felt from taking these three products:

  • Increased muscle hardness and fullness
  • Improved mass gains
  • Enhanced vascularity
  • Testosterone suppression

All in all, I felt good while taking this stack, but the testosterone suppression kicked in pretty hard. It ended up causing fatigue and decreased libido for a few weeks.

That's because the Andro's cause hormonal suppression, meaning you will need to take a post cycle therapy afterward. So make sure to purchase a PCT and use it after if you're going with this stack.

The Ultimate Mass Stack is roughly $275 and will last you a week. We find it quite expensive, and you're going to have to spend another $50 to $100 on a post cycle therapy supplement.

#3. Animal Stack

The last muscle building stack on our list is the Animal Stack by Universal Nutrition. It consists of three staple supplements which are the Animal Pak, Animal Flex, and Animal Whey.

These three products will be useful for those that want to improve their physique. As someone that has used the Animal stack, here's what I noticed:

  • Improved energy and power
  • Accelerated recovery
  • More mass growth

I'll be honest; I didn't find it effective for building muscle as the first option on this list. These products focused more on power and recovery for me, but that could be different for you.

Since these products contain quite a few ingredients, you're going to be taking many capsules each day. So if you aren't used to doing that, perhaps a different option would suit you better.

You can find the Animal Stack for sale on various supplement retailer websites. Generally speaking, it goes for around $125.

Should You Use A Muscle Building Stack?

If you're eating right and training hard, I absolutely recommend adding a muscle building stack to your routine. When you've got all the aspects covered, you're going to be gaining size very quickly.

Try and use the stack for as long as possible, preferably 8 to 12 weeks. I found that the longer you use them, the better everything gets.

To give you an idea, with the Advanced Anabolic Stack, I managed to pack on roughly 10lbs with an 8-week cycle. There aren't a lot of supplements out there that could make me achieve similar results.

Long story short, if you're looking to get a stack, make sure to pull the trigger and start taking one as soon as possible as they can have a massive impact.

Are Muscle Building Stacks Safe?

We can't speak for all the muscle building stacks out on the market, but the three options in this article are safe. Otherwise, we wouldn't be recommending them.

There's nothing to worry about when taking them, meaning you won't get any side effects. Even if you take them for more extended periods, it's OK to do so.

But make sure you're taking the proper dosages - don't take extra pills because that won't speed up your results. If your bottle says to take two capsules, take two - no more.

If you follow the guidelines closely, you'll be able to see significant results within just a few weeks. It's also a good idea to add other supplements such as BCAAs or a post workout to maximize your performance.


Taking your performance to the next level is challenging, but adding a muscle building stack to your routine makes things a lot easier.

Not every combination of products out there is worth using, simply because they could be too weak for putting on size. That's why we've put together a list of the 3 best stacks for muscle growth.

Here's a recap of the options we featured in our article:

  1. Advanced Anabolic Stack – visit & shop
  2. Ultimate Mass Stack
  3. Animal Stack

They're all great options for packing on size, but of course, the first option has our preference due to potency.

Add one of these to your routine, and you'll start noticing the effects within a week.
