Recently, I made it my mission to test and review every single weight gainer on the UK market. I wanted to keep the project UK-focused so that I wouldn’t have to take out a second mortgage to pay for delivery costs.

But as my reviews began to go viral, I got more and more requests to do a Transparent Labs Mass Gainer review. At first, I refused. But after looking into the product a bit more and being impressed with the ingredient purity, I caved in and ordered a tub.

So this one’s for all my American readers. I hope y’all (that is you all, in case there are any Brits reading) appreciate my investment!

Let’s see how Transparent Labs Weight Gainer stands up to my strict British scrutiny.

Transparent Labs Mass Gainer Ingredient Quality

The supplement facts for Transparent Labs Mass Gainer

Holy macros! That’s what I first said when I saw the Transparent Labs Mass Gainer ingredient list. I’d heard on the grapevine that Transparent Labs used premium ingredients (which you do pay for), but I didn’t expect macros like this.

Per 2-scoop serving, you get:

  • 750 calories
  • 110g of carbs
  • 53g of protein
  • 14g of fat
  • Only 12g of sugar
  • 3g of creatine monohydrate

The 2:1 carbs-to-protein ratio is ideal for hardgainers (and anyone who lifts, really) to gain quality muscle mass without piling on the fat. I love how Transparent Labs uses organic tapioca maltodextrin rather than the horrible GMO maltodextrin that you find in virtually every other mass gainer.

The Transparent Labs Mass Gainer ingredients

And 14g of fat! Healthy fats like these MCTs are ideal for bulking because they’re calorie-dense (9 calories per gram) and quickly absorbed, meaning that they don’t slow down protein absorption, which is important if you take your weight gainer after a workout.

The icing on the cake, especially for a health-conscious person like me, is that Transparent Labs Mass Gainer is 100% free from artificial sweeteners, colouring, and preservatives. There’s also no gluten or GMOs, so this supplement is easily the best gluten free mass gainer for a lot of people.

Grass-Fed Whey Protein

Nobody will dispute the fact that grass-fed cows produce the highest quality milk proteins. So why do virtually no other supplement brands use grass-fed whey protein in their mass gain formulas?

To keep costs down, that’s why.

The scoop size for Transparent Labs Mass Gainer

Worse still, many brands artificially inflate their gainer’s protein content with cheap filler amino acids like taurine. Some even use soy protein. No thanks.

On the other hand, this Transparent Labs Weight Gainer contains 53g of 100% grass-fed whey protein, so it’s no wonder that people are experiencing great gains from drinking these calorie-dense shakes.

You know, with some of the big-name mass gainers, you’d need to use twice as much powder to get this much protein (how do they still get away with that?!).

So far, I’m really impressed with how nutrient-dense this Transparent Labs Gainer is. I suppose that you can fit a lot of protein into your powder when you don’t cram your formula with all those nasty fillers.

Quality Carbohydrates

The nutrition information for Transparent Labs Mass Gainer

Like many enthusiastic lifters, I’m all about getting those gains and setting new PRs. Yet, I’ll never sacrifice my health in pursuit of muscle mass.

This is why I typically steer clear of weight gainers that contain maltodextrin.

However, unlike the genetically-modified maltodextrin that you find in most other gainers, Transparent Labs Mass Gainer uses only organic tapioca maltodextrin, which is naturally produced and, therefore, not only healthy but much easier on your stomach as well.

So if you’re used to feeling sick or bloated from your mainstream mass gainer, drinking Transparent Labs Weight Gainer will be a welcomed change to both your stomach and your taste buds (more on the taste in a minute).

Healthy Fats

It seems like with weight gainers, you either get no fat whatsoever, or you get so much fat that your mass gainer basically turns into a fat gainer.

Personally, I like my mass gainer to have balanced macros, which is exactly what you’re getting with this Transparent Labs gainer and it’s 14g of fat, which is derived from coconut milk and MCT oil.

As you probably know, consuming enough fat is vital for optimal testosterone production, which is why it really bugs me when brands boast about their mass gainers being super low in fat, as if it’s somehow a good thing.

Unlike virtually any other weight gainer on the market, Transparent Labs Mass Gainer actually has more fat than sugar, which is a sign that the ingredients are ultra-pure.

While this might scare off a few gullible gym bros, savvy supplement users know that fat isn’t the enemy. Indeed, with twice the energy density of protein and carbs, fat can be your secret weapon for cramming in those extra crucial calories during a bulk.

Zero Fillers

Look at the nutrition label on your average mass gainer. I’ll bet that there are at least 3 ingredients that you can’t even pronounce.

And while mainstream supplement brands might think they can hide their fillers and junk ingredients behind fancy tradenames, the truth is catching up to them—fast.

Supplement users are more science-savvy than they were 10 years ago. Many of us are no longer fooled by fancy packing and outrageous claims. We look at the ingredient label, check out the customer reviews, and then make a decision.

With absolutely zero fillers or artificial ingredients, this Transparent Labs Weight Gainer really does live up to its name. 

While this gainer is more expensive than average, you’re also not paying for any junk, so the overall value for money is actually pretty good, especially if you go for their subscribe & save option.

Transparent Labs Mass Gainer Benefits and Effectiveness

Reading through the Transparent Labs Mass Gainer reviews, I couldn’t help but notice the high praise for this weight gainer’s ability to produce results in a safe and effective manner.

The Transparent Labs Mass Gainer nutrition facts

So, as you can imagine, I had high hopes—especially given that it cost me a fair bit to order from the UK!

I have to say, my experience with this Transparent Labs Gainer matched that of the hundreds of satisfied customers.

Unlike other gainers, which taste extremely artificial and sit heavy on your stomach, Transparent Labs Mass Gainer goes down really easily and doesn’t cause any stomach discomfort or bloatedness because it has 100% clean ingredients.

As such, you’ll actually be able to look forward to your mass gain shake rather than dreading the unpleasant side effects and the sugar crash. Ultimately, this means you can drink your Transparent Labs shakes consistently and maximise your muscle growth!

Personally, with Transparent Labs Mass Gainer, I found that my energy levels were way more stable than when I forced myself to gulp down mainstream mass gainers.

Obviously, since I’ve been training hard for over a decade, I didn’t gain massive amounts of muscle mass from taking this gainer. However, many people did; and they got really good results in both hypertrophy and strength.

Transparent Labs Mass Gainer Taste Test

I can safely say, that after taste testing around 65 different weight gainers, there’s nothing worse than having to gulp down a sickening shake after you’ve just given your all in the gym.

Most brands fill their gainers with so many junk ingredients that they’re forced to use dangerous amounts of artificial sweeteners and colourings just to make their shakes drinkable.

With just a bit of stevia extract, I wasn’t expecting my Transparent Labs Mass Gainer to taste amazing. But honestly—and I very rarely use this word to describe a mass gainer—the flavour was nothing short of delicious, and that’s with both water and milk.

I got the Chocolate Glaze Donut flavour, which I initially thought would be a bit too indulgent for my mild British tastes, but to my surprise, the flavour struck the perfect balance between not being bland and not being too sweet and overpowering.

My shakes also didn’t have that grainy, cement-like texture that often makes you gag when drinking low-quality weight gainers.

Overall, while taste and mixability aren’t as important as ingredient quality and purity, it’s cool to see that Transparent Labs is leading the supplement industry in both the flavouring and nutrition departments.

How To Use Transparent Labs Weight Gainer For Optimal Results

As with any supplement, you’ll get the best results from your Transparent Labs Mass Gainer when you take it consistently, ideally every day.

Some novice lifters might think that drinking a weight gainer on their rest days is unnecessary.

However, I’d argue that rest-day nutrition is just as important as training-day nutrition because your muscles are repairing and (hopefully) growing when you’re resting—not when you’re in the weight room.

Muscles are stimulated in the gym, but they’re built at home via your recovery, which consists of diet, sleep, and supplementation.

So, for best results, I’d definitely recommend taking your Transparent Labs Weight Gainer on a daily basis.

Transparent Labs Mass Gainer Side Effects

Everyone reacts differently to supplements. For example, I have near-perfect lactose tolerance and can drink milk until the cows come home, but I have friends who simply cannot stomach anything with milk protein.

But since this Transparent Labs gainer contains 100% clean ingredients, it’s unlikely to cause gastric distress for most people.

That said, if you’ve never drunk a weight gainer before, then a full 750-calorie serving might make you feel a bit full at first. Transparent Labs actually recommends starting with half a serving per day if you’re new to mass gainers, which will help ease your stomach into the new calorie surplus.

Obviously, if you’ve been drinking mass gainers for years like me, then you can drink a full serving on day one without any issues.

Transparent Labs Mass Gainer is a solid weight gainer for women and for men because it contains quality, natural ingredients that will help anyone gain weight, regardless of whether you’re a novice lifter or a competitive bodybuilder.

In this regard, It’s also a safe mass gainer for teens who need a supplement that’s 100% clean (nothing artificial) and 3rd party lab-tested.

Is Transparent Labs Weight Gainer Worth Buying For Bulking Up?

Well, I promised myself that I’d stick to UK products for this project. But my persistent and enthusiastic American readers tempted me to try this Transparent Labs weight gainer.

And honestly, I’m glad that I did.

While the shipping was a little pricey to the UK, I simply can’t fault the flawless nutrition that this Transparent Labs gainer offers. 

With 100% grass-fed whey protein, healthy fats, and clean, complex carbohydrates, this formula contains everything you need to gain weight and muscle mass.

Overall, if you’re fed up with poor-quality weight gainers that leave you feeling undernourished and bloated Transparent Labs Mass Gainer will be a breath of fresh air.

Best of all, for my US readers, you can save 10% on Transparent Labs Supplements and get free shipping when you subscribe and save.

And yes, my fellow Brits, Transparent Labs do ship to the UK as well. But I’d recommend ordering a few tubs at a time to make the shipping costs worthwhile.

Thanks for stopping by and reading my Transparent Labs Mass Gainer review. I really loved trying and testing this weight gainer, and I can’t wait to try some more Transparent Labs supplements soon.
