Transparent Labs Mass Gainer: 110% Open Formula Weight Gain!

Transparent Labs Mass Gainer

As part of a new 2.0 face lift for the brand, Transparent Labs has release a new Mass Gainer that brings NutraBio-level transparency.

It’s been quite a while since we’ve heard any rumblings from the crew over at Transparent Labs in California. Fear not, the guys have quietly been busy, upgrading their entire lineup with new ingredient labels that approach a new level of transparency — “110% transparency” that we’ve only seen out of NutraBio!

But today, we’re here to talk about the popular online company’s newest product, a weight gainer that shows what the future of Transparency looks like.

The first of these new wave products is the Transparent Labs Mass Gainer, and when we say it packs a tremendous caloric load. If you’re needing to pack on some extra weight, but want to know where every last milligram of your product is used, then take a look at the new label they’ve got for you!

The details are below, but before that, take a moment to check the best deal and sign up for PricePlow alerts and stay on top of our Transparent Labs coupons, because it’s definitely not cheap:

Transparent Labs ProteinSeries Mass Gainer Ingredients

TL’s Mass Gainer is part of their new “v2.0 lineup”, where all of their products are getting a facelift more or less in the transparency of their labels. They’re is stepping up their game and giving us NutraBio-level transparency in terms of labeling, even down to the amount of sweeteners used in the product, as you’re about to see.

This product is formally called the “ProteinSeries Mass Gainer” but we’re just calling it Transparent Labs Mass Gainer. It stays true to keeping things 100% natural, even with the whopping dose of their carb source:

  • Organic Tapioca Maltodextrin (100g)

    Transparent Labs Mass Gainer Ingredients

    Everything even down to the amount of cocoa and salt is detailed out for the extremely curious.

    We’ll start off the analysis with an ingredient you are probably partially familiar with, the complex carbohydrate maltodextrin. This is a common carb found in many other mass gainers and intra/post workout supplements, but more likely than not, it’s not derived from organic tapioca like this version is.

    Derived from 100% pure tapioca starch, this form of maltodextrin is hypoallergenic, non-GMO and certified kosher.[1] FYI, virtually all maltodextrin you’ll find in other products are derived from GMO corn.

    When you get down to what maltodextrin actually is, the ingredient is all the same, GMOs or not. This one just happens to have a far more natural basis, which pleases many of Transparent Labs’ customers. Basically, malto is a polysaccharide (complex carb) comprised of short chains of bonded dextrose molecules.

    Researched benefits of maltodextrin in athletes

    You’re already aware that this is primarily here for its caloric impact on the product, but did you also know consuming maltodextrin either during or after exercise significantly increases endurance and glycogen replenishment, while also lowering fatigue.[2,3]

  • New Zealand Whey Protein Concentrate (62.5g)

    The sole source of protein in Mass Gainer is 100% Grass-Fed New Zealand Whey Protein Concentrate (WPC) from the same supplier that also provides TL with Whey Protein Isolate (WPI) for their Transparent Labs 100% Grass-Fed Whey Isolate product.

    While both are derived from whey, WPC is a less refined (more “natural” and closer to the source) compared to WPI as it undergoes one less step in processing at the manufacturing facility. This means that WPC ultimately has more fats and carbs than WPI[1], as well as more calories overall, which is exactly what you’d want in a mass gaining powder.

    WPC-80 Whey Protein Concentrate Confirmed!

    The bad news is that Transparent Labs forgot to put what grade of WPC they used. Whey protein concentrates can vary in their protein content between 35 – 80%, where the WPC-80 is higher quality form.

    The good news is that WPC-80 has been confirmed by Transparent Labs staff, and they will be updating the label as soon as possible.

    This is exactly what we had hoped for – more protein by weight means less junk and impurities!

  • The Rest

    Transparent Labs Mass Gainer Ingredients Poster

    Mass Gainer packs one heck of punch in terms of macros. You get all of these in just ONE SCOOP!

    The remainder of the ingredients in Mass Gainer address all of the flavoring, textural, and sweetening needs of the powder. Fear not, these ingredients are just as transparently dosed as the two heavy hitters above.

    Rounding out the label, we have Coconut Milk Powder (6.65g), Natural Chocolate Flavor (6.3g), Cocoa (6), Medium Chain Triglycerides (5.71g), VitaFiber (3g), Creatine monohydrate (3g), Sodium Chloride (1.2g), Oat flour (1g), and Sweet Potato Powder (1g).

    In terms of additional sweeteners (aside from maltodextrin), Mass gainer uses a combination of Stevia (200mg) and Monk Fruit (200mg) to lend a subtle sweetness to their powder – not much is needed when you have that many carbs!

Mass Gainer Macros

TL’s Mass Gainer is a true behemoth, even amongst other mass gaining protein powders in terms of not only scoop size, but also caloric density. Each serving (1 scoop) of Mass Gainer clocks in at a towering 196.76g and contains the following:

  • Calories: 750
  • Protein: 53g
  • Carbs: 109g (15g sugar)
  • Fats: 12g (6g saturated)

Even if you’re on a high-carb, high-protein diet, this may slant you a bit deep into the carb territory. This is a great thing for those of us who have trouble staying on top of our high carb load day in and day out, but if that’s not a problem, you’re going to need to make sure you get enough high-protein sources (like steak!) to balance things out. All in a day’s bulking!

Flavors Available

Transparent Labs PreSeries Earned

Gains don’t come on their own, you have to be willing to bust you butt each and every rep of every set.

As we’ve seen with just about all of Transparent Labs products, flavors are at a premium especially given the fact that they are all naturally flavored and void of any and all artificial sweeteners like sucralose or Ace-K. Given the difficulty of getting stevia-sweetened products just right, it makes sense that as of right now, Mass Gainer only comes in the chocolate flavor.

Hopefully, once the rest of the “facelift” for TL’s other products is complete, they’ll circle back to their protein powders and expand the flavor lineup.


If you’re looking to put on mass in the cleanest way possible, short of only relying on whole foods, it doesn’t get much better than Transparent Labs Mass Gainer. Free of all GMO-free maltodextrin and grass-fed GMO will definitely appeal to the “natural” crowd out there and is a nice compliment to TL’s promise to remain free of artificial colors and sweeteners.

The price of TL’s Mass Gainer may not be the cheapest on the block (even with our exclusive Transparent Labs Coupon), but remember with protein powders, you ultimately get what you pay for. Extremely cheap weight gainers are often spiked with amino acids, leaving you with a protein that contains just a fraction of what the label states.

Transparent Labs Isolate powder currently presides as the #1 naturally sweetened whey protein isolates on our Best Protein Powders page, and if/when we get to a Top 10 Mass Gainers Guide, you can rest assured this one will make this list as well – we can’t think of many other purely natural options out there, so thank you to Transparent Labs for the unique product and the 110% transparent labels!
