Walk into any Walmart or CVS and you'll see it. The shiny silver and blue box. Six Star Pro Nutrition. It’s sitting right there next to the protein powder and the pre-workout, promising to help you "amplify" your testosterone and boost your performance. But let’s be real for a second. Most guys standing in that aisle have the same nagging thought: Does Six Star Testosterone Booster work, or is it just another bottle of expensive pee? It’s a fair question. The supplement industry is basically the Wild West, and when it involves hormones, the marketing usually gets pretty aggressive.
The short answer? It’s complicated. It isn't a magic pill that turns you into a professional bodybuilder overnight. It isn't even actual testosterone.

Instead, it is a blend of minerals and herbal extracts designed to support your body's natural production. If you’re expecting the effects of an anabolic steroid, you’re going to be disappointed. Period. But if you’re looking for a specific, science-backed mineral boost that might help with recovery and free testosterone levels—specifically if you're already training hard—there is actually some data worth looking at.
Breaking Down the Six Star Formula
When you flip that bottle over, you aren't going to find a list of twenty different ingredients. Six Star keeps it surprisingly simple compared to some of those "proprietary blends" that hide everything behind a curtain. The heavy hitters here are Boron and a combination of Rhodiola and Ginkgo.
Let’s talk about Boron first. This is arguably the most legitimate part of the formula. There was a notable study published in the Journal of Trace Elements in Medicine and Biology where researchers gave healthy male subjects 10mg of boron daily. After just one week, their free testosterone levels increased significantly. Why? Because boron seems to decrease Sex Hormone-Binding Globulin (SHBG).
Think of SHBG like a sponge. It floats around in your blood and soaks up testosterone, making it "bound" and unusable for your muscles. By lowering SHBG, more of the testosterone you already have becomes "free" and active. Six Star gives you a 100mg dose of Boron Citrate, which yields about 5mg of active boron. That’s a decent start, though many enthusiasts prefer hitting that 10mg mark seen in the studies.
The Anti-Catabolic Angle
Then you’ve got the Rhodiola crenulata and Ginkgo biloba. This isn't really about "making" more testosterone. It’s more about protection. These are adaptogens. When you crush a heavy leg day, your cortisol levels—the stress hormone—spike. Cortisol is the enemy of testosterone. They have an inverse relationship; when one goes up, the other usually goes down.
Six Star claims this specific blend helps maintain a better testosterone-to-cortisol ratio after intense training. Basically, it’s trying to keep you in an "anabolic" (growth) state rather than a "catabolic" (breakdown) state. Does it work? Some research on Rhodiola suggests it can help with fatigue and mental focus during exercise, which might indirectly help you train harder, but it’s not exactly a hormone-replacing powerhouse.
What It Won't Do (Setting Real Expectations)
We need to clear the air. You’ve probably seen the ads with the massive guys who look like they were carved out of granite. Those guys didn't get that way just by taking a supplement from the grocery store.
If your testosterone levels are clinically low—we're talking "go see a doctor" low—this supplement is not a replacement for Medical Testosterone Replacement Therapy (TRT). It just isn't. If you have a legitimate medical deficiency, a herbal blend isn't going to move the needle enough to fix the symptoms of hypogonadism like extreme fatigue, depression, or loss of libido.
Also, don't expect a massive "pump" or immediate strength gains the day you take it. This isn't caffeine. It doesn't kick in thirty minutes after you swallow the caplets. Any potential benefits from boron or adaptogens take time—usually weeks of consistent use—to manifest in your blood chemistry.
The Quality Control Question
One thing people often overlook is where Six Star comes from. It’s made by Iovate Health Sciences, the same parent company behind MuscleTech. Now, regardless of how you feel about big supplement brands, there is an advantage here: scale. Because they are a massive company, they usually have pretty strict third-party testing and cGMP (Current Good Manufacturing Practice) standards. You generally don't have to worry about the pills being contaminated with weird fillers or unlisted ingredients, which is a massive problem with smaller, "underground" supplement brands you find on Instagram.
However, "safe" doesn't always mean "potent." Some critics argue that the dosages in Six Star are on the lower end of the spectrum. For example, it lacks Vitamin D3, Magnesium, and Zinc (the ZMA combo), which are the actual building blocks of testosterone production for most men. If you are deficient in Zinc, taking Six Star might not do much because you're missing the foundational raw materials.
The Verdict: Who Is This Actually For?
Honestly? This supplement is for the guy who is already doing everything else right.
If you are sleeping 8 hours a night, eating enough healthy fats (cholesterol is the precursor to testosterone, folks), and lifting heavy weights, then Does Six Star Testosterone Booster work as a little extra "edge"? Maybe. It might help nudge your free testosterone levels up a bit thanks to the boron. It might help you recover a little faster from a brutal session.

But if your diet is trash and you're only sleeping 5 hours a night, this bottle is a waste of twenty bucks. You can't supplement your way out of a bad lifestyle.
It’s also worth noting the price point. Six Star is usually one of the cheapest options on the shelf. In the world of supplements, you often get what you pay for. While the boron is a solid inclusion, the rest of the formula is a bit "light" compared to premium (and much more expensive) boosters that include things like Ashwagandha (KSM-66), Fenugreek, and D-Aspartic Acid.
A Quick Word on Side Effects
Most guys handle it fine. It’s pretty mild. But, some people report stomach upset or headaches, likely from the Ginkgo or the fillers used in the caplets. Always take it with food. And for the love of all things holy, talk to a doctor if you’re on blood thinners or heart medication, as Ginkgo can interact with those.
How to Maximize Your Results
If you decide to give it a shot, don't just pop the pills and hope for the best.
- Check your Vitamin D levels. Most men are deficient, especially in winter. No "booster" will work if your Vitamin D is tanked. Pair your Six Star with a high-quality D3 supplement.
- Focus on compound lifts. Squats, deadlifts, and overhead presses naturally stimulate hormone production. The supplement is meant to supplement that stimulus.
- Cycle it. While there's no hard rule, many guys find that taking boron for 2-3 weeks and then taking a week off helps keep the body from adjusting to it.
- Manage your body fat. Body fat contains an enzyme called aromatase, which converts testosterone into estrogen. The leaner you are (within a healthy range), the better your natural hormonal profile will be.
Actionable Steps for Natural Support
If you’re serious about your levels, Six Star is just one tool in the shed. Start by cleaning up the basics. Track your sleep for a week; if you aren't hitting 7+ hours, start there. Add a Zinc supplement if you don't eat much red meat or shellfish. These changes will likely have a bigger impact on your T-levels than any herbal blend ever could.
If you do buy the Six Star bottle, use it consistently for at least 30 days before deciding if it's working. Look for changes in recovery and morning energy rather than "becoming the Hulk." Real progress is slow, boring, and usually involves a lot of chicken breasts and heavy iron.
