Sergeant Steel Review
Named Sergeant Steel, coming from Assault Labs and promising military grade T boosting, the theme of this product is clear.
To us, Sergeant Steel just sounds like a guy who turns up to a bachelorette party with a boom box and a bride-seeking-missile under his rip away khakis. But hey, if we dismissed every booster with a cheesy name we’d hardly take any.
This brand promises to:
- Boost muscle mass
- Increase stamina
- Raise libido
- Improve strength
A big plus right away is that there are no proprietary blends here. That means every ingredient is individually dosed on the label. Full info is always a must. So let’s see if male stripping’s loss really is T boosting’s gain. And if he’s stainless steel or just the mild variety…
How Does It Work?
At a Glance
- Ashwagandha to raise endurance
- Fenugreek to balance blood sugars
- D-Aspartic Acid & Vitamin D3 to boost T
- Maca & Longjack for libido
- Tribulus allegedly to help test levels
We’ll dig deeper into Steel’s make-up after the scores
Sergeant Steel is one of those products that has a massive ingredients list. Trouble is that to squeeze that many ingredients in one product, you may end up with underdosed elements. As is the case here … however only for a couple of them (courtesy of having to take 10 pills a day).
Vitamin D3 is at 60% of the dose we’d like to see. Magnesium is 50% of the dose, and Zinc 50%.
There are loads of positives in this formula though. Boron, DAA, and Ashwaghanda are all good t boosting ingredients and dosed at proper levels. Similarly, Nettle Root, Fenugreek and Macuna Pruriens are all ingredients we like, and they are dosed at good levels.
The others – Trib, Maca, and Shilajit should have been dropped to increase the dosages of D3, Magnesium and Zinc.
Overall, a couple of mis-fires aside … good choices here and well thought out formula.
Even the very best boosters we’ve reviewed wouldn’t get full marks at $50 a bottle. It’s expensive. However, you get what you pay for and it’s a solid product.
There’s nothing dangerous about Sergeant Steel, it’s manufactured in line with cGMP regulations. Also they don’t use proprietary blends, opening all formula info up to the user which is great. There’s not much available about Assault Labs, so the score isn’t perfect.
This product generally has quite high star ratings but unlike Generals, boosters need more than stars to prove their quality.
When it comes to testimonials the more detail the better. Ideally you should be looking for full names of users, photos and videos, rather than stars and a brief paragraph no matter how positive.
There’s not a lot of info out there on Assault Labs and they don’t appear to have a stand alone site. This isn’t ideal but we’ve no reason to believe they are any kind of scam as the modest range of 5 or 6 supplements are carried by several online stores and we couldn’t turn up any worrying scandals.
How Do I Take It?
Users should take 5 caps, twice a day.
This looks great on paper. 10 caps a day sounds like you’re getting plenty of help. However, it’s no good having a big arsenal if you don’t use it correctly.
It’s not about the number of capsules, it’s about number of servings and placement. All those 5 capsules will start to fade at the same time, so just 2 servings will leave gaps in the day when you’re getting no help.
Any Sergeant Steel Side Effects?
There’s really nothing that gives us much to worry about as far as side effects. Just be mindful of any individual allergies.
Where Can I Get It?
Sergeant Steel is available from strongsupplementshop.com for $50 and £37
Ingredients – In Detail
Vitamin D3 is a good idea. It’s actually hormone in its own right and proven to help raise T at doses above 3000IUs. Sadly we’ve only got half that here so it’s not much use.
Magnesium is great for your free T. That’s T not kept out of action by a protein called SHBG. Enough of this mineral can actively lower your SHBG count giving you more to work and play with. 50mg perserving is less that we’d like to see and will be of limited use though.
Zinc is another solid pick. It provides a solid foundation for healthy T by stimulating building blocks like luteinizing hormone, growth hormone and follicle stimulating hormone. You’re safe tolerance for zinc is about 30mg so 15mg per day is disappointing again.
This product is definitely dropping all the right names so far. D-AA is an amino acid which is great for to T stimulating a lot of the same key players as zinc. 3000mg is right on the money.
Ashwagandha is an adaptogen, meaning it is able to help your body better deal with stress. This includes the type it comes under from exercise so in theory it is able to extend your workout. 675mg daily dosage is exactly the amount you’d want to see.
Another useful pick here. Mucuna pruriens, sometimes called velvet bean stimulate the amino acid L-DOPA in our system. This not only promotes androgens for T production, but cuts down on cortisol. Cortisol is a stress hormone which blocks male hormone so reducing it gives a boost both in T and mood. 250mg is a good amount.
The beta sitosterol in nettle means like magnesium it is good for lowering your SHBG thus freeing up more of the T in your system. 250mg per serving again is another useful dose.
A great multi tasker in these supplements. Not only does it stimulate androgens and boost your sex drive, it also balances you blood sugars. This is important because in well regulated inslin levels, stopping them getting in the way of T production.
Utterly useless. Briefly thought to be a potent T booster, most clinical trials have shown it has no influence on your hormones. The only plus here is we just have 50mg per serving, but why have it at all?
Some promise here for the traditional medicine favorite. Modern trials show it can promote luteinizing hormone one of the building blocks for T. Most studies have been carried out on infertile males and we’d like to see a bit more work done before getting 100% behind this.
An ingredient of many names (aka longjack, tongkat ali) but pretty few talents. Only really good for giving for stimulating libido. 100mg per serving won’t do much for your T.
Found in certain fish, and supposedly able to help block estrogen, which is good as when your female hormone is up, your T is down. And vice versa. Unfortunately there’s very little clinical evidence that this actually works in humans.
Boron is a great choice. The mineral can raise T and lower estrogen giving us the perfect balance. It can with a pretty small dose too, 5mg per day is spot on.
Another libido booster and not much else.
A proven estrogen blocker like vitamin B6 would have been good, the Trib could have made way for that.
Overall we are impressed with Sergeant Steel. Would we follow Sergeant Steel into battle? We would, although maybe not on Operation Certain Death. He’s got bottle. Or rather, the right things written on his bottle.
Drop and gimme 100. Better still, drop the Trib and other duds and you’d be looking at the top 3 podium.
