1st Phorm Phormula-1

1st Phorm boasts that their Phormula-1 whey protein is one of the best-tasting products on the market. It mixes well and contains 20 grams of protein in each serving. A low-temperature processing method has been used to increase assimilation speed and amino acid retention. You can pair Phormula-1 with other 1st Phorm products, such as their Ignition Recovery supplement.

This product is unique in that it includes whey protein isolate, whey protein concentrate and hydrolyzed whey protein.

What is Promix Grass-Fed Whey Protein?

Comprised of whey protein concentrate, Promix Grass Fed Whey Protein has a complete profile of omega-3 fatty acids. It’s made from milk from grass-fed cows that are rBST-free. Each serving contains 25 grams of protein and nothing artificial. This is a very clean product that features traceable testing for every batch.

Six different flavors are available, including chocolate, unflavored, vanilla and peanut butter. Promix flavors their products using actual food. Their peanut butter chocolate variety is made using Texas peanuts and raw organic cacao.

My Experience With Promix Whey

I used Promix Whey with good results. Here’s what I thought:


I tried the chocolate peanut butter version of Promix Whey as well as the unflavored variety. I like the unflavored option because I can add it to my fruit smoothies that I make first thing in the morning for breakfast. The peanut butter variety was a bit sweet. I liked it later in the day for an afternoon snack.


Promix blends together very quickly. I often added it to a shaker bottle, and it took about 20 seconds to mix. It also mixed very well in my blender.


I like the amount of protein that’s in this product. To consume 25 grams in a single serving was an excellent option for me when I wanted to ensure I had enough energy for a workout. I also feel like this product helped me with my recovery time.

What is Transparent Labs Grass-Fed Whey Protein?

Transparent Labs Grass Fed Whey Protein is one of my favorite protein-focused products. It’s hard to find a product that provides more protein than this. With an average of 28 grams of protein per serving, I noticed I was much more energetic when I used this product. I looked forward to getting my workout in. I also felt full for longer periods of time, so I didn’t feel the need to snack as much throughout the day.

This is a very pure product that helps hydrate the muscles, enhance blood flow and balance nitric oxide production in the body.

My Experience With Transparent Labs Whey

I have been using Transparent Labs Whey for a couple of years now. It’s a product that I currently have in my pantry right now. Here’s what I think of it:


I love the taste of Transparent Labs Whey Protein. My favorite flavors are dark chocolate and sugar cookie. They are a bit sweet, but not overwhelming at all. The texture is very smooth, adding to the overall taste.


I like how Transparent Labs Whey mixes. I’ve used it both in a shaker bottle and in a blender. It blends a little better with a blender, but shaking it for about 30 seconds results in a very smooth beverage.


I love the protein content of this product. It helps energize me and boost my recovery after working out. I’ve even used this product when I wasn’t feeling well in order to get some additional calories in my body.

How do these two whey protein options match up? Read on to find out more.

Comparing Formulas

The formulas for these two products are pretty similar. They are both based on whey that is sourced from grass-fed cows. You don’t have to worry about hormones or antibiotics being in the final product.

You do get a few extra grams of protein in Transparent Labs’ product. Depending on the flavor, TL has 28 grams of protein in each serving, compared to 25 grams in Promix products.

Comparing How It Mixes and How It Tastes

Both Promix and Transparent Labs have protein powders that mix incredibly well. Like I mentioned, I’ve mixed them both using a shaker bottle as well as a blender. I like the final product when using a blender, but they’re both very smooth as long as you shake them long enough.

The taste of both products is very good. Depending on the variety, I find some of the flavors for each brand to be a little sweet. However, it’s nice that both companies offer an unflavored version that I can add to a fruit smoothie.

Comparing Price

The cost of Promix Whey Protein is currently $49 for a one-time purchase. This is a very affordable price compared to other similar products on the market. You can save a few extra dollars by signing up for a subscription or buying larger quantities of product.

Transparent Labs sells their Whey Protein Isolate for $59.99 for a one-time purchase. A subscription saves you $6 and includes free shipping.

What Are the Main Differences Between Promix and Transparent Labs?

The main difference between these two products is that Promix uses whey protein concentrate. Transparent Labs uses whey protein isolate. The difference between these two ingredients has to do with how they are processed. Isolate tends to have a bit more protein, less carbs and less fat.

Also, Transparent Labs offers more flavor options. I prefer that Promix uses natural ingredients to flavor their products, whereas Transparent Labs uses non-organic natural flavors.

Final Thoughts

If you’re looking for a whey-based protein powder that provides clean protein without unnecessary ingredients or additives, both Promix and Transparent Labs offer excellent options. I’ve used them both, and I can say that they’re both incredibly high-quality protein supplements.

My Recommendations

I would recommend looking at both of these products a little more in depth to see if one stands out more than the other. Transparent Labs offers the protein isolate option, which increases protein and lowers fat and carb content. However, Promix is still an excellent product to consider.


Promix Whey Protein is better for…

  • Clean and natural protein
  • People who want protein concentrate over isolate

Transparent Labs Whey Protein is better for…

  • A higher protein content
  • Low-fat and low-carb
