As a certified personal trainer, nutrition coach, and longtime lifter, there’s one supplement that’s remained in my routine for years: protein powder.
While it’s probably the most popular product within the health and fitness community, you don’t have to be a competitive athlete to reap its rewards. In fact, I’d argue that just about everyone could benefit from keeping a tub of high-quality protein powder in their cabinet.
After all, even if you’re dialed in with your diet, it can be tough to get a sufficient amount of this important macronutrient solely through food. Luckily, there are plenty of delicious, well-formulated protein powders available that can help you hit your daily goal.
Having tried dozens of brands dating back to my high-school football days, I’ll acknowledge that some are better than others simply on taste. However, at BarBend, we know not to judge a protein powder on flavor alone. Hence, we’ve developed a comprehensive supplement testing methodology that allows us to get a full understanding of what’s inside the tub.
For this 1st Phorm vs Transparent Labs comparison, I tried similar flavors from both brands so I could deduce their differences and see how they stacked up against each other. After testing their top protein powders for three weeks, I’ll be as transparent as possible so you can form your own opinion about which direction to go.

What Is Transparent Labs?
Although it hasn’t been around for quite as long, Transparent Labs has quickly earned a reputation as one of the top supplement manufacturers since it launched in 2016. Headquartered in Utah, the brand focuses on science-backed, all-natural supplements with no artificial sweeteners and fully transparent ingredient labeling (hence the name).
Unlike 1st Phorm, Transparent Labs doesn’t offer apparel or accessories. However, the brand has a diverse supplement lineup that includes BarBend favorites like Creatine HMB, Hydrate (a great product for endurance athletes), Lean Pre-Workout, and BulkBlack Pre-Workout—a high-stim formula that earned strong praise from our team (check out our Bulk Black review for more details).
Of course, for this article, I’m pitting protein powders against each other, which puts the focus on Transparent Labs’ flagship product: Grass-Fed Whey Protein Isolate. So, while the brand does offer a mass gainer, grass-fed protein shakes, and whole-food protein bars, I’ll let you shop for those on your own.
1st Phorm vs Transparent Labs: At a Glance
The BarBend team is no stranger to either of these two brands. In fact, we’ve done a full 1st Phorm Phormula-1 review, and another expert review on Transparent Labs Whey Protein Isolate, too.
However, we can always do better (and provide some new perspective).
So, for this head-to-head battle, I also tried 1st Phorm Level-1, a slow-digesting protein blend that’s a bit higher in calories than Phormula-1. Before I go into each component of our testing process, here’s a high-level overview of all three protein powders I tested for this comparison piece.
| 1st Phorm Phorm ula-1 | 1st Phorm Level-1 | Transparent Labs Grass-Fed Whey Protein Isolate | |
| Calories per serving | 100-110 cal, depending on the flavor | 130-150 cal, depending on the flavor | 120-150 cal, depending on the flavor |
| Protein per serving | 23g | 23-24g, depending on the flavor | 28g |
| Type of protein | Whey protein isolate | Whey protein concentrate | Grass-fed whey protein isolate |
| Sweetener | Sucralose | Sucralose | Stevia extract |
| Number of flavors | 13 | 12 | 22 |
| Third-party testing | Informed Choice Certified, NSF Certified for Sport | Informed Choice Certified, NSF Certified for Sport | Informed Choice Certified, Informed Protein Certified |
1st Phorm vs Transparent Labs: The Nitty Gritty
Now that you know a bit more about both companies, let’s get granular about each powder. I’ll provide my feedback and analysis on 1st Phorm Phormula-1 and Level-1, as well as Transparent Labs Grass-Fed Whey Protein Whey Isolate. I’ll also relay further insight from a registered dietitian.
Formulation
For the closest apples-to-apples comparison, let’s start with Phormula-1 vs. Transparent Labs’ protein powder.
The former delivers 23 grams of protein per serving with very little fats and carbs (just 0.5 grams and between 0.5 to 1 gram, respectively). As a pure whey protein isolate, this is a great option if you’re trying to lose weight, as you get a great protein-per-calorie ratio. While it’s not totally lactose-free, it’s “virtually void of lactose and fats,” which is especially useful if you have dairy sensitivities.
It’s worth noting that 1st Phorm uses sucralose (1) in both Phormula-1. That may be a dealbreaker for those who want to steer clear of artificial sweeteners, but the formula checks most of the boxes we look for at BarBend.
“It’s a great high-protein option that delivers bioavailable proteins for pre- and post-workout use or as a supplement to improve your protein intake,” says our expert registered dietitian, who rated the formulation a 4 out of 5.
RELATED: Do Artificial Sweeteners Make You Fat?
Meanwhile, Transparent Labs is slightly higher in calories, coming in at 120 to 150 calories per serving, depending on the flavor. However, that’s not necessarily a bad thing.
As a whey protein isolate, this product is similar to Phormula-1 in that essentially all of the calories come from protein. Transparent Labs ranges between 0-3 grams of fats and 0-3 grams of carbohydrates while delivering 28 grams of protein per scoop. Coupled with the fact that it contains stevia extract (a natural sweetener), and this meets the definition of a clean protein powder with a clinically-dosed formula.
Meanwhile, Level-1 is a bit different since it’s a protein blend—not a pure isolate. You get 23 to 25 grams of whey protein concentrate per scoop, making this a better option if you’re looking for a slow-digesting protein. Each serving also provides 5 grams of BCAAs (branched-chain amino acids), and 2 grams of glutamine, which has been shown to help with muscle recovery (2).
Because it’s low in fat and carbs (and still fairly low in calories), however, you shouldn’t look at Level-1 as a meal replacement.
“The lack of macro and micro nutrients and fiber makes it better for supplementation versus complete nutrition,” says our expert RD, who rated Level-1’s formulation at a 3.5 out of 5. “However, I like that it’s processed with low-temperature techniques to protect the bioavailability of the proteins.”
If we’re comparing Phormula-1 to Grass-Fed Whey Protein Isolate, I’ll give the slight edge to Transparent Labs because it uses a natural sweetener over an artificial one. However, I wouldn’t have any problem making Phormula-1 my primary protein powder, especially if I was in a cutting phase where I wanted to keep my calories low and my protein high.
The Winner: Transparent Labs (slightly)
Solubility
Solubility is one of the key areas we assess with protein powders because, let’s be honest: nobody wants to sip on something that’s gritty or clumpy.
To assess this thoroughly, I didn’t just rely on the old shaker cup method. I also wanted to mix these into other liquids to see if the solubility was different with just water.
My other methods included using a NutriBullet blender with ice to create a true “shake” consistency. I also mixed each protein powder with coffee (after letting it cool slightly) in the NutriBullet to create an upgraded morning cup of joe.
The results?
Both 1st Phorm protein powders dissolved completely in my shaker cup after shaking it for about 30 seconds and letting it sit for about 15 seconds. There was no residue on the bottom of the cup, and zero clumps or grit.
The NutriBullet also did its job effectively when I mixed Phormula-1 and Level-1 (separately, of course) with ice and water, producing a smooth, creamy concoction that was reminiscent of a Wendy’s Chocolate Frosty. The protein coffee pairing also yielded a pleasant result, as I thoroughly enjoyed having a hint of chocolate in my typical cup of black coffee. It also created a creamy texture similar to a latte.
As for Transparent Labs?
I had a very similar experience, as it mixed without issues with all blending techniques. To be honest, you couldn’t discern any differences between either brand.
So, even though I’d love to say one was the clear winner, both are winners here.
The Winner: Tie (both mix great!)
Taste
Taste is obviously subjective, but to keep things as objective as possible, I tested the Phormula-1 Chocolate Milkshake flavor vs. Transparent Labs’ Milk Chocolate Grass-Fed Whey Protein. I also got the Milk Chocolate version of Level-1, so truly this was about as close a comparison as you can get.
While I wouldn’t call myself a chocoholic, I generally go for that flavor with my protein powder because I do have a HUGE sweet tooth.
Luckily for me, 1st Phorm satisfied that craving.
Phormula-1 tasted almost exactly like a real-deal chocolate milkshake—even when I just mixed it with water. If you use milk, almond milk, or a plant-based alternative, you can achieve an even better result, especially if you blend it with ice.
Meanwhile, pitting Level-1 directly against Transparent Labs allowed me to get a true A/B test of which Milk Chocolate formula tasted better. I literally prepared two separate shaker cups with one serving of each powder, plus about 6 ounces of cold water. Both gave me a bit of a nostalgic Nestle’s Quick vibe, but Level-1 (as well as Phormula-1) had a slightly sweeter undertone that I suspect is due to the sucralose.
That punch of artificial sweetener may not be for everyone’s palette, but it made my taste buds do a proverbial happy dance. For me, 1st Phorm—at least based on my experience with the Milk Chocolate and Chocolate Milkshake flavors—earns the nod over Transparent Labs.
The Winner: 1st Phorm (especially if you have a sweet tooth)
Third-Party Testing
Third-party testing should give you peace of mind and full confidence about whatever you’re sipping on. Luckily, both brands do an excellent job of putting their products through rigorous protocols.
1st Phorm Phormula-1 stands out because it’s not only Informed Choice-certified, but it’s also NSF Certified for Sport. This is particularly important for athletes, as this certification ensures products are free from banned substances, heavy metals, and harmful contaminants. Meanwhile, Level-1 is also Informed Choice-certified, and some (but not all) flavors are NSF Certified for Sports. You can check out the official NSF website to verify which 1st Phorm products carry this certification.
Meanwhile, Transparent Labs has built its reputation upon being completely transparent about its third-party testing protocols. Grass-Fed Whey Protein carries an Informed Choice certification as well as an Informed Protein certification, which verifies that the actual amount of protein matches up with the listed amount. Transparent Labs also provides a Certificate of Analysis (COA), ingredient verification results, and the amino acid profile on its site.
Ultimately, both brands deserve a tip of the cap for being open about what’s inside the tub. I don’t think you can go wrong with either one, so between Phormula-1 being NSF Certified for Sport (a huge plus) and Transparent Labs providing detailed third-party testing information, I can’t go with one over the other.
The Winner: Tie (you can sip with confidence!)
Price Per Serving
Finally, let’s get to the all-important price per serving.
After all, many of us (myself included) weigh the price pretty heavily when deciding on which supplement to add to our stack. Here’s a breakdown of the cost for all three products if you make a one-time purchase:
| Phormula-1 | Level-1 | Grass-Fed Whey Protein Isolate | |
| Cost | $69.99 | $62.99 | $64.99 |
| Total Servings | 30 | 30 | 30 |
| Price Per Serving | $2.33 | $2.10 | $2.17 |
Clearly, there’s not a huge price difference between any of these protein powders. However, Transparent Labs is slightly more affordable by about $0.16 per serving over Phormula-1.
Of course, if you end up liking one of these products and want to keep it in your rotation on the regular, you could sign up for a subscription.
Transparent Labs offers $7 off a subscription for a 2-pound tub, lowering the total cost to $58.49.
Meanwhile, 1st Phorm offers $7 off for Phormula-1 with a subscription, lowering the total cost to $62.99. You can get $8 off for Level-1, reducing the total cost to $54.99.
One important caveat here is that while Transparent Labs offers free shipping with a subscription, 1st Phorm only offers free shipping for orders of $150 or more. Here’s a complete breakdown of their shipping policies:
- First subscription order: If the order subtotal is under $150 after discounts, standard shipping rates apply based on the carrier’s rates.
- Future subscription orders: Orders under $150 receive a flat $5 shipping rate. Orders of $150 or more after discounts qualify for free standard shipping.
- One-time orders: Orders of $150 or more after discounts qualify for free standard shipping. Orders under $150 have shipping charges applied at checkout.
Given the value add of free shipping and the lower overall cost (even without a subscription), Transparent Labs has the edge in this category.
The Winner: Transparent Labs (though it’s not a huge gap)
The Final Word on 1st Phorm vs Transparent Labs
Choosing the best protein powder involves more than just looking at which brand offers the most robust lineup of flavors. You need to carefully evaluate the formulation in order to determine whether it aligns with your dietary preferences and health and fitness goals. In addition, you should pay close attention to solubility so you’re motivated to keep sippin’.
Finally, third-party testing is critical, as you shouldn’t have any hesitation about putting something in your body because you don’t know where it was made, how it was made, or what exactly’s inside the tub.
As someone who’s tried dozens of protein powders over the last two decades, I’ll admit it can be tough to narrow down your choices to just one or two. There are truly many high-quality options on the market, and both 1st Phorm and Transparent Labs offer well-formulated protein powders that can help support your muscle growth and strength-building goals (as well as your overall health).
If you’re weighing your options, consider whether the taste is more important than the cost. If so, I’d lean toward 1st Phorm. Ditto if you’re looking for a lower-calorie option in order to support your weight-loss goals. On the other hand, if you want the best bang for your buck, you get a little bit better value with Transparent Labs.
However, my ultimate takeaway after trying Phormula-1, Level-1, and Grass-Fed Whey Protein Isolate is that all three are great-tasting protein powders that can fit seamlessly into your diet. It all depends on your goals and preferences, so I encourage you to try them and see what you like best.
After all, every palate is different, and only you will know which powder deserves your undivided attention and hard-earned money.
