Growing up in the 90s, the first supplement that we all had high hopes for improving the natural production of testosterone was the Bulgarian herb Tribulus Terrestris. Of course, it was marketed in a hyperbolic manner like everything else at the time in the 1990s a practice that continues to this day. One company said It was the secret of the high-performing Bulgarian Weightlifting Team. Anytime a supplement is marketed as a secret of any group or team, or something that was used in ancient times to increase vitality and virility, avoid it like the roulette tables on the Vegas strip. Tribulus came in a packet that looked like actual medicine including each tablet being in a blister pack. This provided the illusion of being a serious product with potent effects. Of course, Tribulus didn’t work. It didn’t work then, it doesn’t work now, and won’t work a hundred years from now. I don’t care what level of saponins it has or what the protodioscin level is. It flat-out doesn’t work. It may have benefits in other areas such as reducing high blood pressure and supporting kidney health but it definitely doesn’t work for increasing testosterone.
Some take Tribulus and experience an increase in libido and assume that it must be working to increase testosterone as a result. The increase in libido is either a placebo effect or some other mechanism such as possibly improving kidney health, as it’s definitely not from an increase in testosterone. Also, for the most part, increasing libido generally involves more than just increasing testosterone but that is a story for another time. There are a few herbs that can increase libido such as maca and yohimbe but neither has an impact on improving testosterone levels.
Most don’t get before and after blood work to determine the effectiveness and just go by how they feel. Something many supplement companies are well aware of and take full advantage of. Fortunately, many of my customers are just as enthusiastic about hormone optimization as I am and get blood work done regularly which is why, unlike other companies that sell testosterone boosters, I have numerous testimonials from ASTB customers revealing clearly the big increases in total and free testosterone they experienced (Scroll to the bottom to see some ASTB testimonials).
Over the years I have tried many supplements to increase testosterone such as Tongkat Ali, fenugreek, and D Aspartic acid, and none of them were effective. The first herb I ever tried that resulted in a large increase in testosterone was the cornerstone ingredient in ASTB the one and only Bulbine Natalensis. I learned about this South African herb from my friend Anthony Roberts (Not to be confused with Anthony Robbins!) in 2010. Anthony has written books about steroids and is extremely well-researched in ergogenic aids natural and unnatural. Anthony learned about Bulbine from our mutual friend Carl Lanore the host of the best fitness podcast, Super Human Radio. Carl had a doctor on his show that revealed that Bulbine increased testosterone in rats by 347%. Personally I don’t care about what works in animal studies. I am against animal studies morally and they have little carryover in what works for people or what is safe for people to take. However, Anthony had used Bulbine himself and had lab work to show it definitely increased his own production of testosterone without any negative impact on health parameters such as lipids, liver enzymes, and kidney markers. The rat studies showed Bulbine at the highest dosage of 100mg/kg had a negative impact on liver and kidney health. Of course, 100mg/kg is a very high dosage and no one is taking anywhere near that amount. Rather 400 mg to 800 mg is the range that works well for most men. I personally take around 650 mg and I have been using ASTB for ten years (8-12 weeks on 4 weeks off) and my liver and kidney markers are always in the normal range. It definitely hasn’t had a negative impact on my cholesterol either as my total cholesterol on my most recent blood test was 133mg/dl with an HDL of 55 mg/dl and LDL of 66 mg/dl. Total testosterone was 733 ng/dl and the more important free testosterone was 105.7 pg/ml.
As effective as Bulbine Natalensis is on its own, in my opinion, there is synergy with using it with Mucuna Pruriens and Stinging nettle root. Mucuna is an incredible herb that ramps up dopamine which is just as important as testosterone for improving sex drive as well as motivation in general. Mucuna is why many ASTB users feel the effects on the very first dose. Not everyone of course, but many experience the increase in dopamine before the increase in testosterone from Bulbine which generally takes a few weeks. Mucuna is also a pro-testosterone herb and like Bulbine increases luteinizing hormone which the brain sends to the testes to ramp up testosterone production. Mucuna has also been shown to support insulin sensitivity and growth hormone levels. Stinging nettle root doesn’t increase total testosterone like Bulbine and Mucuna, but helps unshackle the more important free testosterone from the sex hormone binding globulin. Remember, free testosterone is the number that matters the most as it is what you have access to. This doesn’t mean total testosterone is worthless, something my friend and hormone optimization expert, Dr. Mark Gordon professes. Generally, only 2% of your total testosterone is going to end up as free testosterone so the higher your total testosterone the high the 2% number can be for free testosterone. 2% of a total testosterone of 300 ng/dl obviously is not as high as 2% of a total testosterone of 800ng/dl. Some men only have access to 1% or less of total testosterone for a variety of reasons and will need an even higher level of total testosterone to in turn increase free testosterone unless they use stinging nettle root which can help unbind free testosterone and make it more bioavailable.
One thing you will not see with how I market ASTB is any hyperbolic over-the-top marketing. I am not going to promise that you will experience rock-hard erections like when you were a teenager or that you will put on 20 lbs of muscle in a month. No ASTB is not going to make you feel like an ancient warrior ready to conquer the world and take charge of every facet of your life. No supplement works that well (Even TRT doesn’t work that well!). The men that acquire the best results with ASTB are the ones who are already practicing a lifestyle dedicated to health and fitness. Effective supplements are meant to do just that supplement, not make up for an unhealthy lifestyle. If you enjoy drinking alcohol every day which increases estrogen and lowers testosterone, sleep four hours a night, abuse stimulants such as caffeine which increases cortisol and lowers testosterone, sit on the sofa all night watching Netflix, and consume an unhealthy diet don’t expect any supplement including ASTB to be beneficial.
The bottom line, is I don’t need to hype up ASTB or insult your intelligence or attempt to feed on your insecurities to get you to make a purchase. I know it works and so do most of my customers as it only has a 2% non-responder rate calculated on the number of refund requests I get. The actual account of refund requests I get is actually lower than 2% but I present it higher to take into account people that don’t bother asking for a refund and simply never purchase it again.
I only recommend and certainly only sell things that have worked well for me. Whether it is training advice, nutrition advice, business advice, or effective supplements if it failed to work for me I move on. Unlike owners of many supplement companies, I actually am dedicated to a health and fitness lifestyle and have the results to back that up. Anyone who follows me on Instagram knows I still train like a savage and I am in better shape now at nearly 50 than I was when I was in my 30s and began learning about hormone optimization. Unlike the “Liver King”, I am not claiming to be natural while simultaneously taking TRT and Growth Hormone. I am open about whatever I am using or have used such as SARMs, Peptides, and Clomid.
I don’t believe for a second that I need to lie to you to sell you anything. Sure I enjoy making a great income just like anyone else would, but I sleep with a clear conscious every night knowing that I am not selling overhyped ineffectual products that don’t deliver. In addition, I provide a ton of effective information for free on hormone optimization, training, nutrition, supplements, and restoration to ensure you have access to the best info to help you get the most out of ASTB and my other supplements. Also, when you buy ASTB you have access to me the guy who designed the product and is extremely well-versed in all things hormone optimization to answer your questions by email. How many other supplement companies can say that? If you don’t get the results you desire with ASTB the refund process is easy. You don’t have to call a customer service line and explain to someone over the phone why you want a refund. You don’t have to wait 90 days for the refund to be processed like I did when I canceled my DirectTV account many years ago.
I detest companies who insult my intelligence and try to place me in a fear-based mindset to initiate action. I also hate when salespeople use my name too much but I digress. If you don’t think ASTB or any other product I sell is a fit for you, no big deal, enjoy the free information I deliver, and all the best to you. I want the best for my visitors and customers and I have even had people that inquire about ASTB and upon reviewing their blood work I let them know it is not likely to work for them. How many companies do that? If you have high luteinizing hormone but still have low testosterone then no natural testosterone-boosting option including ASTB is likely to work. I am not going to lie to you just to make a sale. There is a reason why I have been in the fitness industry for over twenty years and why my supplement company is successful. It’s not from spraying the money hose on marketing and advertising, it is from designing products that work, explaining the benefits in a clear straightforward manner, showing actual concern for my customers, and wanting the best for them. My philosophy is to make great products that work and offer tons of free content to establish value. This in my experience leads to tons of repeat business as well as referrals. You can’t buy a great reputation, you have to earn it over many years. There are no shortcuts, just ask anyone who tried and ended up on an episode of American Greed.

Mike, I just had to tell you how awesome this product is. Honestly, I wasn’t expecting it to do much (no offense intended). My total test was 275 last time I had it checked. I took one bottle of Aggressive Strength and had a blood test on the last day (day 45) and my total T was up to 879! I would have been happy with 600. Incredible. I feel good, and strong. Thank you!

I just received my blood work after finishing the 8-week cycle of T-boost. Blood work before starting the 8-week cycle: Total testosterone was 715 ng/dL. The free test was 5.6 pg/mL After an 8-week cycle on Aggressive Strength Total T was 940 ng/dL….Free T was 33.3 pg/mL (it was flagged as being too high!) Aggressive Strength Testosterone Booster is the REAL DEAL….I am a 59-year-old male…I was at the LLA Podcast kettlebell summit in Vegas this past Sept.

I just wanted everybody to know this, my testosterone level before I used Mike’s testosterone supplement was 350. I only did one eight weeks cycle and have not used it in three months. I got my testosterone checked the other day and I am at 620!! I can’t wait to do my next cycle of this. Let’s get it up to 1200?? Lol
