In the supplement market, there are great pre-workouts and there are the best pre-workouts. If you've been using supplements for a while, German American Training and Cellucor are no stranger to your ear. These two giants have two of the best-selling products but are Nitraflex and C4 really all they're cracked up to be? Let's review these two supplements to see which one is worth picking up.
Where can I buy it?
- Here's where you can buy GAT Nitraflex.
Pros of GAT Nitraflex
Right away, you can see that GAT's Nitraflex is geared towards a male audience and this has everything to do with the fact that there is a testosterone support agent inside of this pre-workout. I'll speak more on that below.
As to the pre-workout itself, Nitraflex hosts an impressive combination of ingredients that combine stimulants and nootropics, or 'brain boosting' compounds. Ingredients of note are the following:
- Similar to Yohimbe in structure and function
- Supports weight loss
- May trigger boost in norepinephrine (energy) without an increase in blood pressure (1)
- Famous stimulant
- May significantly boost your energy levels
- May increase mental focus and alertness (2)
- May be beneficial for neuromuscular health
- May boost focus and memory
- May prevent feeling of anxiousness, which is common feeling with stimulants (3)
Cons of GAT Nitraflex
There are two concerns with Nitraflex that I have: First, GAT uses a proprietary blend. This is frustrating because you don't know exactly how much of a certain ingredient you're getting in this blend. With the blend being 7.2 grams, you have to wonder just how effective the pre-workout can be. For example, elite pre-workouts use 2 to 3 grams of Beta Alanine alone. With that said, this is an impressive line-up and at 7 grams, there should be a decent amount of everything in there. As always you can double the dose.
The only other issue we have is with marketing. By adding the unproven testosterone booster into the pre-workout, GAT is losing out on a potential female market. I'd say ditch the unproven t-booster and market to everyone.
Where can I buy it?
- Here's where you can buy Cellucor C4.
Pros of Cellucor C4
C4 by Cellucor has been dominating the pre-workout market for a long time. User reviews report that C4 gives them the energy they need without the crash that comes with caffeine-dominant supplements. This may be directly related to the use of Theacrine, which is considered a softer cousin of caffeine. One study revealed that taking a mixture of both caffeine and Theacrine resulted in an increase in cognitive function and energy without the rise in blood pressure associated with other stimulants. (4)
Cellucor C4 is also backed by Beta Alanine, Arginine Alpha Ketoglutarate, and Creatine Nitrate. Again, you're looking a solid line-up of ingredients that have all been the subject of research, study, and fanfare.
Cons of Cellucor C4
Like GAT, Cellucor uses a proprietary blend when it matters most. They do reveal that C4 only has 150 mg of caffeine per serving but you're left in the dark with the other 275 mg of the blend. With that said Cellucor does provide the information for most of the other ingredients, which is helpful. As I mentioned above, you could double the dose, if need be, but I feel as if one serving will be plenty considering ingredients like Beta Alanine are dosed appropriately.
You have two industry giants with two amazing products. It's impossible to choose between them because both have so much to offer. Despite relying on proprietary blends, GAT and Cellucor are providing products that are sure to get you through your workouts. I really like the addition of Theacrine in C4 but I'm also a huge fan of the Raulwolfia in Nitraflex. I'd suggest buying both and see which one is better for your body type.
