Bigger By The Day® With Turk Vs Bigger By The Day® With Laxogenin


Many of you remember when 5% Nutrition’s innovative Bigger By The Day® first hit the market. What a product! One of the key things about the original version was the combo of Laxogenin and Epicatechin, backed up by several key ingredients including Leucine. Now, we’ve replaced Laxogenin with the more powerful Ajuga Extract (Turkesterone). In this article, we will look at the differences between the two and see why the updated Bigger By The Day® with Turk is more powerful than ever!

What Is Laxogenin? 

The original Bigger By The Day® contained a potent 150 mg dose of laxogenin per serving. There are 2 forms of this compound. The first is 5 Alpha Hydroxy Laxogenin, a synthetic version. The other form is Smilax sieboldii, a natural version. Both versions have the same benefits. These benefits include increased protein synthesis, improved strength, and anti-catabolic properties. (1)

Why Has Laxogenin Been Pulled Off The Market By Some Companies?

Laxogenin as 5 Alpha Hydroxy Laxogenin is the version that was recently the target of “concern” by the FDA. The agency sent a letter to several companies implying that this version of Laxogenin is not a natural dietary supplement. Regarding the FDA letter, they requested specific reasons why companies felt 5 Alpha Hydroxy Laxogenin was a natural ingredient. Since then, the FDA has gone further and stated that this version is not isolated from a plant. Therefore, according to the FDA, it’s not natural and has been pulled from the market. Of course, 5% Nutrition pulled the original Bigger By The Day® immediately.

Yet the benefits of Laxogenin can’t be denied so we wanted to find an ingredient that was even more impressive. 

Enter Bigger By The Day® with Turk!

What sets this powerful compound apart? Let’s find out! First, Turketerone comes from the Ajuga plant. This is a plant that has a naturally high content of ecdysteroids. Turkesterone is the most potent ecdysteroid. (2)

Of course, that’s the one we wanted in Bigger By The Day®!

Besides being the strongest ecdysteroid, Turk has several in-vitro studies supporting its benefits. (2)

One primary benefit of Turk is that it stimulates protein synthesis. This is huge. That’s because protein synthesis directly activates muscle growth. Bigger By The Day® with Turk is one more tool to help you achieve your muscle mass goals. This outstanding formula also contains Leucine and HICA. Both of these are involved in the process of protein synthesis (especially Leucine). (3, 4)

We wanted to make Bigger By The Day® more powerful than ever - and we succeeded!

Stack It!

Yep, you can stack Bigger By The Day® with other key 5% supplements to dramatically enhance protein synthesis! For example, stack it with ADYM. One serving contains 6g of BCAAs in an exclusive 10:1:1 ratio. That means you’re getting a generous dose of Leucine. ADYM also contains EAAs and CEAAs. Plus, there’s Drink Sleep Grow with the revolutionary Active TR Leucine. This is a time-released Leucine that’s taken at night. Who said sleep had to be catabolic? Not with 5%!

What Else Does Turkesterone Do?

Along with enhanced protein synthesis, Turkesterone supports increased strength. Plus, Turk also has anti-catabolic properties. Add to the fact that we used a very generous 1g dose and Bigger By The Day® becomes a must-have for your mass-gaining supplement arsenal!

How Do I Use Bigger By The Day® For Optimal Results?

Since Turkesterone stimulates protein synthesis, it’s suggested to be taken with a high-protein meal. Therefore, take Bigger By The Day® with your two highest-protein meals of the day. This is where 5% protein shakes can also help you out. Right after your workout, do what Rich did and have a shake consisting of Real Carbs. You can add Egg White Crystals or Shake Time. Either is the perfect high-protein complement to Bigger By The Day®!


Leave it to 5% Nutrition to react quickly to changing market conditions by creating updated formulas that exceed your expectations. Bigger By The Day® with Turk is one of the best examples of 5% innovation. It’s always been a potent formula that would have made Rich proud. Now with Turk, it’s better than ever!
