Purus Labs D-Pol

Purus Labs D-Pol

Purus Labs D-Pol was designed kind of as a pre-workout/testosterone hybrid basically with the idea of providing users with duel benefits:

• Boosted testosterone
• Increased nitric oxide

If Purus Labs D-Pol really works it should benefit men who exercise regularly and want to improve their workouts, muscle mass, strength and body composition.

Purus Labs claims D-Pol is supported by research. So, I decided to find the truth about Purus Labs D-Pol.

Does Purus Labs D-Pol Contain Effective Ingredients?

I didn’t have to look far for research on the ingredients because the official website provides several references.

D-Aspartic Acid – Men with low testosterone took D-aspartic acid during a 12-day study. On day 6, increases in luteinizing hormones and testosterone were noted. On day 12, luteinizing hormones had increased 33% and testosterone had increased 42%.[1] Researchers believed testosterone levels would have continued to rise if the study had lasted longer.

D-aspartic acid is an amino acid found in hormone-producing tissues. It increases testosterone by triggering luteinizing hormone release. Luteinizing hormones stimulate the testes to produce testosterone.

Nitratine – Purus Labs provides several studies showing nitratine increases nitric oxide.[2][3][4] Nitric oxide’s main purpose is to relax and widen blood vessels, which increases blood flow. As blood flows more freely, oxygen and nutrient delivery improve. Muscle pumps increase and muscles heal faster. Erections and cardiovascular health are enhanced as well.

Vitamin D3 – Vitamin D3 improves calcium absorption, strengthens bones, and may prevent high blood pressure, osteoporosis, and cancer. But perhaps the best benefit for men is vitamin D3’s ability to elevate testosterone. When study participants took vitamin D3 daily, their total, free, and serum testosterone levels increased significantly. Whereas, the placebo group didn’t notice any changes.[5]

Research shows the ingredients are safe. My only concern is I don’t know if Purus Labs D-Pol has the right D-aspartic acid and nitratine dosages. During studies, the participants took these ingredients in liquid form, but Purus Labs D-Pol contains the solid form. Accurately converting liquid measurements to solid measurements is very difficult.

How Much Should You Take?

Purus Labs D-Pol comes in 2 forms: tablets or powder. Each container holds 30 servings. For powder, 1 scoop equals a serving. For tablets, a serving is 3 tablets.

Purus Labs says consumers only need 1 serving a day. Taking more may not improve results, but may cause harm or side effects.

Take 1 serving an hour before exercise with food.

Purus Labs D-Pol doesn’t contain stimulants. However, the company says you get better results by taking it during the day. Do not take Purus Labs D-Pol before bedtime.

Purus Labs D-Pol Customer Reviews

58 Purus Labs D-Pol users have left feedback and ratings on Amazon.com. The average rating given was 3.3 out of 5 stars. Here are the individual ratings:

• 5 stars: 13 users
• 4 stars: 16 users
• 3 stars: 13 users
• 2 stars: 10 users
• 1 stars: 6 users

It concerns me there are almost as many 2 and 3-star ratings as 4 and 5-star ratings. These ratings show Purus Labs D-Pol is an above-average testosterone supplement, but it doesn’t rank with the best ones.

Many users said Purus Labs D-Pol boosted testosterone, improved workouts, and helped them build muscle. Users who gave lower ratings said the supplement didn’t make any-or-much difference. Side effects such as bloating, acne, and stomach pain were mentioned by a few users.

The Purus Labs D-Pol powder is “Custard Creme” flavored. I don’t know if users liked the powder’s flavor or mixability because no one mentioned it.

Several users complained the tablets were too large, chalky, and hard to swallow.

There are only 3 active ingredients in Purus Labs D-Pol, but they are powerful. Clinical studies show D-aspartic acid and vitamin D3 increase testosterone levels considerably. Nitratine was proven to improve blood flow and provide numerous benefits.

Many users liked Purus Labs D-Pol, but many also said it was just an average testosterone supplement. Side effects didn’t affect most users.

Overall, Purus Labs D-Pol is a good testosterone supplement, but it’s not the best. If you buy it on sale, Purus Labs D-Pol may give you your money’s worth.

Nathan Bishop Says:

I absolutely love D-POL. I can definitely feel of boost of energy when I take it with a light meal about an hour before training. Another thing that I’ve noticed is that it keeps me freaking horny! All in all its a great product and stacks well with many other products.
