USP Labs Test Powder Review, Any Side Effects?

USP Labs’ Test Powder is one of the most popular testosterone booster supplements on the market, due to the marketing of USP Labs. However, are the ingredients proven enough to warrant such hype?

Ingredients and Doses

Thumbs up to USP Labs for letting us see the ingredients and some of the exact doses. Other testosterone booster supplements can hide the amounts of each ingredient, in which case we don’t know if the dosage is high enough to be effective.

Dreaded Proprietary Blend

On the flip side they do include a “proprietary blend” of Trimethylglycine, L-carnitine Tartrate, Aframomum Melegueta Extract and Garcinia Mangostana. For example I know that 230mg of Aframomum Melegueta Extract is effective for boosting T by 300%, based on a conclusive study done on rats. But we do not know the dose of Aframomum Melegueta Extract in USP Labs’ Test Powder, so it could well be less than optimal.

Some companies like to hide the doses of certain ingredients like this, to cut down on costs. This way the company saves money and at the same time people recognize the ingredient based on proven studies that it increases T.

D-Aspartic Acid – 3120mg

I’m a big fan of D-aspartic acid. In my opinion this is one of the best testosterone boosting ingredients available. A dose of 3120mg is a good dose for this amino acid.

D-aspartic acid has been proven to raise T levels by 46%. Not only is this a significant rise, but the speed at which d-aspartic acid builds up in your system is impressive. In one study, this 46% increase took place in just a 2 week period. Testosterone boosters often take a while to kick in, so this immediate effect is great.

Agimatine Sulfate – 1000mg

Agimatine has shown to stimulate LH (luteinizing hormone) production. This in turn elevates Testosterone levels. Agimatine also regulates insulin levels. This is beneficial as too much of insulin causes the body to shift into a state of storing fat.

Agimatine isn’t completely side effect free, with cases of nausea and diarrhea being reported in some users.

Mucuna Pruriens Extract – 200mg

The case of mucuna pruriens raising test levels is very debatable. This is because studies have shown mucuna pruriens extract to provoke a steady rise in testosterone levels in infertile men. Thus, some would say mucuna pruriens would only be effective if a man has a pre existent deficiency.

In several studies, mucuna pruriens was given at a dose of 5g per day. Thus with a dose of 200mg there is no guarantee that mucuna pruriens will be effective at this dose as there is no current evidence to support this.

Usage Instructions

I am a little baffled why they USP Labs recommend cycling a d-aspartic acid based testosterone booster. They recommend cycling 6 days on and 1 day off. For a testosterone booster to be effective, it has to build up in your system over at least a month or 2 to see any great effect. This is done with consistent dosage each day.

When cycling 6 days on, 1 day off, it will decrease this build-up effect. D-aspartic acid, the main ingredient in Test powder, does not need to be cycled in this way – so I find this instruction a little strange.

Side Effects

The main negative side effect being reported on the web and forums is having the “squirts”. This really means diarrhea. Frequent “wet farts” have also been an issue for some. This is quite a humorous side effect to read but from my previous experience, this can actually interfere with workouts!

Servings

USP Labs lists their total servings as 48 scoops (per tub). This could be deceiving to some as it later suggests 2 scoops per serving. Do not confuse this with 48 servings, because, in fact, it’s only half.

Taste

The consensus is that it feels pretty chalky/gritty. Before taking a supplement this really is what you hope it doesn’t taste like. You don’t buy a supplement for it to taste nice so this isn’t a big deal, but at the same time you won’t look forward to taking your next serving.

Conclusion

A big thumbs up for a good dose of d-aspartic acid. But unfortunately from there it’s down hill. The taste isn’t great, the side effects are pretty unpleasant (although not damaging) and the fact you have to remind yourself to stop taking this once a week is not ideal.

TestoFuel – Better Test Booster?

In contrast, a better testosterone booster I have tried is TestoFuel. TestoFuel include a generous dose of d-aspartic acid like Test Powder, but there are little to no side effects and the results for me were dramatic. Below is my 3 month transformation on TestoFuel – after 3 boxes. 

before and after

I gained 1.5″ on my arms after 3 months on TestoFuel. Depending on where you buy from, TestoFuel is a little more expensive than Test Powder. However, you can get a free box of TestoFuel, when you buy 3 – allowing you to save £31 (which’ll help bring the cost down).
