Here's something a lot of men won't admit out loud: nerves are often the real problem in the bedroom. STUD is built around that idea. Instead of a stimulant or a pump formula, it's a calming capsule meant to help you stay relaxed and in control.

Fair heads up, the sales page is written in a very frank, adults only style. It comes from a man who introduces himself as Stirling, a former adult film performer who says he trained as a chemist.

The theory

According to the company, how long a man lasts comes down to a balance between two brain messengers: glutamate, which excites, and GABA, which calms. The company says a diet heavy in MSG and processed food tips the balance toward glutamate, and STUD is designed to help your body shift back toward calm.

Part of the advice is simply to eat less processed food, which is good advice for almost anyone.

The label

The page shows a full supplement facts image. A serving is two capsules, with 30 servings per bottle:

• Folate 340 mcg DFE (200 mcg as L-5-MTHF, or methylfolate)

• Vitamin B12 250 mcg (methylcobalamin)

• Magnesium 200 mg (as magnesium glycinate)

• A 600 mg proprietary blend of L-theanine, rhodiola rosea root extract (3% rosavins, 1% salidroside) and taurine, with no split of how much of each

It comes in a cellulose capsule.

What I like

The quality choices stand out. Magnesium glycinate is one of the gentlest, best absorbed forms of magnesium, and 200 mg is a solid amount. Folate comes as methylfolate and B12 as methylcobalamin, the active forms your body can use right away. Those are details you usually only see in higher end supplements.

Then there's the calming trio. L-theanine, from green tea, is known for relaxed alertness. Rhodiola is a hardy Arctic root used in Scandinavia and Russia for stress resilience, and this extract is standardized to both rosavins and salidroside. Taurine is an amino acid with a calming side.

The company cites a 2016 Italian study on rhodiola and a 2014 study in which men took vitamin B9, which ties the formula back to its theme.

Taking it is easy, too. Two capsules make a serving, and a bottle covers a month. Because there are no stimulants, there's no jittery feeling and nothing that should keep you up at night, which is a real advantage over a lot of men's products.

To me, the real appeal is simple. It's a stress and nerves formula for men, with no stimulants. If performance anxiety is part of the picture for you, that's a sensible approach.

Cost and bonuses

• One bottle: $59 plus $19.95 shipping

• Three bottles: $147 ($49 each), free US shipping, two bonus videos

• Six bottles: $234 ($39 each), free US shipping, two bonus videos

The three and six bottle packages are the way to go, with free shipping and the bonus videos included. You may also see a two bottle offer at $49 each. If a "Platinum Customer Club" option appears at checkout, read its terms so you know whether anything renews.

The company ships in a plain box, which is a nice touch for privacy, and the guarantee runs 180 days.

The right fit

Men who'd like to feel calmer and more in control, who prefer a stimulant free formula, and who appreciate quality forms of magnesium and B vitamins. It's a gentle, everyday kind of support.

If lasting longer is a regular concern, it's also worth having a relaxed chat with your doctor, since there are several approaches that can help and they can work well alongside a supplement like this.

One friendly note. Rhodiola can interact with some medications, including antidepressants, so check with your doctor or pharmacist if you take anything regularly.
