Haymaker Pre-Workout Review


Pre-workouts are a great way to energize, improve your focus and enhance your workout performance. Yes, that means more gains. With so many products on the market each being promoted as the best, you’re bound to get overwhelmed – and be susceptible to impulsive buys. Pre-workouts are often loaded with rubbish ingredients to make it look like you’re getting the best bang for your buck, when in fact it provides no benefit, and sometimes can give unwanted side effects.

No worries, I’ll help you out one step at a time. The pre-workout I’ll be reviewing is Haymaker by Precision Engineered.

What Is It & About

Right off the bat, I can say that I’m not familiar with their manufacturer, Precision Engineered. I did some digging and could barely find any information on them, other than knowing they do manufacture other supplements such as whey protein and BCAA’s. It seems like they don’t have their own website, which is uncommon for supplement manufacturers. If their marketing campaign involves being sneaky, they’re doing a great job.

This pre-workout contains 60 servings, and as I’m aware now, it comes in 5 flavors; Fruit punch, orange, sour apple, strawberry lemonade, and apple.


Let’s get down and dirty with what really matters- the ingredients. Before I start, I’d like to share a BIG positive here. The ingredients are listed individually and not blended into some proprietary blend!

Companies often blend ingredients together so we don’t really know how much of what ingredient is in a serving, thus not knowing if the more expensive ingredients are at an optimum amount. So props to Precision Engineered for that.

I know the ingredients list isn’t clear, but that’s the best I could find (I told you, there’s something mysterious about this company). We’ll go through the important ones, no worries.

1. Beta-Alanine (2,400mg/serving)

This ingredient is crucial in pre-workouts (PWO’s, hereafter). Studies that include supplementation of beta-alanine in test subjects show increase in muscle carnosine.

When our muscles undergo stress due to high-intensity exercise, hydrogen (H+) ions start building up and cause fatigue. Muscle carnosine helps defend against these hydrogen (H+) ions and act as a buffer, meaning you can workout harder and longer.

2. Arginine (1,500mg/serving)

L-arginine is a precursor for nitric oxide. When nitric oxide is released, the blood vessels expand, giving that vascular, veiny look. More blood can flow and bring oxygen and nutrients in quicker, helping to flush out toxin buildup. This prevents injury, improves endurance and improves overall performance. Sounds great? It is.

3. L-Citrulline (1,000mg/serving)

Increases the ornithine and arginine (sounds familiar?) levels in blood. This improves the nitric oxide formation in the body as well as the ammonia recycling system. You feel that intense, hellish burn as ammonia starts building up (err, calves, anyone?) and most people stop, potentially losing out beneficial reps. Again, you’re able to workout a lot longer than usual.

L-citrulline and L-arginine may make you feel better after a gruesome workout session. Increased blood flow helps with nutrient input into the muscle tissues, hence better muscle recovery.

4. Creatine HCL (1,000mg/serving)

Creatine increase the creation of Adenosine Triphosphate (ATP), which basically the body’s primary source of energy. The amount of creatine in PWO’s won’t do much for you, though. Manufacturers add them as fillers to make it seem like you’re getting a lot more than what you pay for.

Creatine is very well researched and has proven benefits, but to successfully consume is at the right doses, you may refer to this article.  Creatine HCl and creatine monohydrate are mainly the same product, don’t get worked up between the two.

5. Agmantine Sulfate (500mg/serving)

This compound is a derivative of l-Arginine and assists with the central nervous system function.

In the world of bodybuilding, agmantine sulfate helps with

  • Improving muscle pumps
  • Aiding mental clarity
  • Improved intra-workout energy

6. Caffeine (200mg/serving)

Caffeine … The world’s most popular drug. All PWO’s have this, and usually at the same dosage. Many of us rely on this to keep ourselves awake and refreshed, but from a health and fitness perspective, there are many benefits of caffeine, such as:

  • Accelerates fat-burning
  • Releases β-endorphins, which makes us feel good during our workouts
  • Increases endurance

Who Should Buy This Product?

I would categorize this as a product for those who are new to taking PWO supplements.  If you’ve got a busy, tiring schedule ahead of you and need to crush those weights in the gym at night, it would be a good idea.

PWO’s are known to be addictive at times, and the more you tolerate them, the more servings you would require. Do keep this in mind, and it’s best to stop consuming them if you don’t really need them.

If you’re pregnant, have nervous system issues or other underlying health issues, due consult a medical professional.

What Customers Are Saying

Based on the research I did, a lot of customers are satisfied with this product, despite not having a clear idea on who the manufacturer is.

Overall, they noticed an energy boost and a decent pump. Would have been better if the dosage of citrulline and arginine was higher, though.

Eric F on Influenster event went to claiming this product is everything Hyde is without the nasty side effects. If you’ve been in the bodybuilding world for a while, you would know Hyde is what stim-junkies go to for a crazy workout.

Generally, you’re not gonna get any side effect’s if you stick to one serving. If you’re going for two, you might expect jittering an a caffeine crash coming your way. Some people are also susceptible to tingling sensations around their body under high concentrations of beta-alanine, so always start small.

Price and Value

So, this product comes in two sizes; 17 oz (40 servings) and 8.5 oz (20 servings).

On Vitamin World, the 17 oz. would cost you $59.99, so it’s $1.49 per serving. The 8.5 oz tub costs $32.99, so it’s $1.65 per serving.

On a per saving basis, and compared to other PWO’s on the market I would say this product is considered slightly expensive, compared to the famous Cellucor’s C4 and BSN’s NO.- Xplode, both at $1.00 per serving. However, it’s not that bad, I’ve seen others go for $1.90 per serving.


I would choose this product over those two any day, as the other two are under dosed in a lot of crucial ingredients and contain proprietary blends, which sucks.

There might be better PWO’s out there I’m not aware of which are slightly cheaper, but unless you’re gonna get worked up about saving a couple of cents, I do think this is good value for your money.

  • It works!
  • Improves workout performance
  • No side effects for a serving
  • Gives a decent pump
  • Can cause jittering, anxiety under large amounts
  • Expect tingling sensations if more than one serving is taken
  • Could be a tad bit cheaper 😀

Final Ratings

Mixability- 10/10

It mixes very well, so a full rating for that one. Just a couple of shakes with 8-10oz of water and you don’t have to worry about clumps stuck in your teeth.

Taste– 6/10

I heard fruit punch and sour apple tastes great! I can’t be certain on the rest because there are not many reviews on this, so I’m not gonna be too optimistic and give this a full rating.

Overall- 6.5/10

Is this slightly expensive? Yes. Slightly. But does it work? It’s a yes too, especially if your body is new to PWO’s. I really don’t see how anything can go wrong with this product.

I would like to give it a higher rating, but I just wish I could find more info on it’s manufacturer. Customer’s confidence is still key!

Before you purchase this product, do check out reviews of other PWO’s on the market here! It’s important to keep your nutrients right. You’re not gonna make any good gains no matter how hard you train if you don’t eat right. Here are tips on what to eat before and after a good workout to make sure you fill your muscles (and eventually your sleeves ?) with the right nutrients.
