Aggressive Strength Testosterone Booster & EC Estrogen Control Bundle

Take advantage of the immense power of the Aggressive Strength Testosterone Booster (ASTB) and EC Estrogen Control combo!*

What ASTB Does

ASTB contains potent extracts of Bulbine Natalensis, Mucuna Pruriens, and Stinging Nettle Root to not only increase overall testosterone production but also make your testosterone more bioavailable. Expect:

  • Increased strength and muscle size

  • Higher libido

  • Lower body fat

  • Better overall mood*

What EC Does

EC contains powerful extracts of Curcumin C3 Complex, Prunella Vulgaris, and Brassaiopsis Glomerulata to:

  • Block conversion of testosterone to estrogen

  • Block estrogen receptor uptake

  • Support fat loss (especially if you store fat in the pecs, stomach, legs, or glutes)

  • Reduce inflammation

  • Improve kidney and heart health*


How Is Aggressive Strength Different From EC?

  • Aggressive Strength is a potent testosterone booster with a moderate estrogen-lowering effect.

  • EC is a potent estrogen control supplement that also provides a moderate testosterone-boosting effect in men.

Women can use EC to address estrogen dominance.
Aggressive Strength is only for men.

EC = Powerful estrogen control for men and women
ASTB = Powerful testosterone booster only for men


Can You Take ASTB and EC Together?

Yes — and you should if your estrogen levels are high.

If you’re overweight, assume your estrogen levels are elevated. High estrogen makes fat loss much harder, so lowering estrogen accelerates fat loss dramatically.

You can also:

  • Use EC between cycles of ASTB

  • Or take a lower dose of EC during ASTB cycles (1–2 capsules per day)


What’s the Best Way to Use the Combo?

ASTB Dosage

  • Under 180 lbs: 1 cap twice a day (morning + afternoon)

  • 180–220 lbs: 3 caps per day (2 in the morning, 1 in the afternoon)

  • 220+ lbs: 2 caps twice per day

More is not better.
Give it a few weeks to kick in. Works best on an empty stomach (1 hr before or after meals).
On training days, take one of the doses 1 hour before training for better focus and performance.

EC Dosage

  • Start with 1 cap twice per day with meals, OR

  • Take 2 caps once per day with breakfast or dinner

Choose whichever method fits your schedule best.

Cycling Protocol

For both products:
12 weeks on → 4 weeks off
This prevents desensitization to the herbs and keeps results strong.


Manufacturing Standards

Yes — all products are manufactured in cGMP-certified facilities. These FDA-enforced standards ensure proper design, monitoring, and control of every step of the manufacturing process.


Satisfaction Guarantee

The ASTB + EC combo comes with a 30-day money-back guarantee for first-time users.

Try it for a month. If you’re not satisfied, email me and I’ll arrange a refund for the purchase price (minus shipping).
If multiple bottles were purchased, unopened bottles must be returned for a full refund on the order.

  • Canada: 7–10 days

Clinical Feedback

*“I received EC from you about 6 months ago and found two males with uncontrolled estradiol increases even on a 40mg every-third-day protocol.
Patient (1) had an estradiol of 67.4 ng/mL with no symptoms of nipple sensitivity or breast fullness. After 90 days on 2 caps/day, his estradiol dropped to 23.7 ng/mL.
Patient (2) began testosterone therapy with an initial estradiol of 117 ng/mL. After 3 months on EC, his estradiol dropped to 42.4 ng/mL.
With the results of these two challenging cases, I will now make EC known to our patients as an option for treating real and presumed elevations in estradiol.”

Real Results With Aggressive Strength & EC Estrogen Control*

“My estradiol dropped from 44 to 17 in 27 days.”
“After my doctor ordered basic blood work and gave me no answers, I ran a male hormone panel on my own. My estradiol came back at 44 (normal is under 39), with low total and free testosterone.
A friend suggested Mike’s products, so I ran 1 month of ASTB and EC (2 ASTB in the morning, 1 in the afternoon; 1 EC twice per day with food). I didn’t change my diet or training.
After only 27 days, my estradiol dropped to 17. There’s only one conclusion: Mike’s products work. I immediately emailed him for a maintenance protocol and ordered more ASTB to finish a full 12-week cycle.”

Gavin Morales


“At 55, I sleep better, build muscle, and feel better than in my 40s.”
“I’ve got my whole family on topical magnesium, and I’ve been stacking EC with ASTB. My Magnesium RBC is 6, total testosterone is 690, and free T is 14.9.
At 55, I have better energy, deeper sleep, and can build and maintain lean mass better than I did in my 40s. Thanks for being the real deal and addressing the real issues that actually move the needle.”

Bill Vogel, Quogue, NY


“Came off TRT cold turkey using EC + ASTB.”
“Your products rock. I got through TRT withdrawals cold turkey with 2 caps of EC twice per day plus the Test Booster for 6 weeks. Took 4 weeks off and now I’m continuing at a lower dose. Thanks for a legit product.”
Dan Doelger


“At 51, I’ve never felt better.”
“LOVE the podcast and your no-BS approach. I love that you limit products, keep quality high, and actually use them yourself. I’ve been using EC and I’ve never felt better at age 51.”
Maria Peden


“Total testosterone: 275 → 879 ng/dL in 45 days.”
“I honestly wasn’t expecting much. My total T was 275 the last time I checked. After one bottle of Aggressive Strength (tested on day 45), my total T was 879 ng/dL. I would’ve been happy with 600. I feel good and strong. Incredible.”
Ian McLeish


“Total T 715 → 940, Free T 5.6 → 33.3 pg/mL at age 59.”
“I just finished an 8-week cycle of Aggressive Strength. Before: total testosterone 715 ng/dL, free T 5.6 pg/mL. After: total testosterone 940 ng/dL, free T 33.3 pg/mL (flagged as ‘too high’).
Aggressive Strength Testosterone Booster is the REAL DEAL. I’m 59 and was at the LLA kettlebell summit in Vegas. Thanks for such a quality product.”

Raleigh Wood


“T 619 → 843, E2 42 → 35, plus better workouts & sex drive.”
“I’m 40, eat all plant-based. Before ASTB, my testosterone was 619 and estradiol 42. After one month, T was 843 and E2 was 35. Huge difference in my workouts and sex drive. Great job putting this together—it works.”
Kevin Brown


“Testosterone 350 → 620 even three months after one cycle.”
“Before using Mike’s test booster, my testosterone was 350. I did one 8-week cycle and didn’t use anything for 3 months. My testosterone is now 620. I can’t wait for the next cycle. Let’s get it up to 1200, lol.”
‘Poppa Pump’ Panezai


“Total T 305 → 724; even my doctor thought I was on injections.”
“You were completely wrong – it worked way better than you said. I finished my first 8-week cycle of your test booster. My T was 305 in December. I started in January, tested again, and it came back at 724.
My doctor accused me of getting injections from another doctor because he’s never seen numbers go up that much from a supplement. My workouts are better than ever, and my fiancée is very happy.”

Art O’Connor


“Total T 330 → 746, Free T to 108; dropped 40 lbs and feel like an athlete again.”
“In 6 weeks on your supp, my total T went from 330 to 746 and free T to 108. Since being at 330, I’ve dropped from 268 lbs to 228 lbs. I feel super-athletic again and I’m pumped for flag football.
Here’s to not feeling like a ‘eunuch’ anymore, like you say. I’m also halfway through Live Life Aggressively—very entertaining and full of truth. Thanks for investing in people’s lives.”

R. Crosley


“Better than TRT for mood for me.”
“I’m turning 45 soon and spent 4–5 years feeling fatigued and too tired to do anything, even train. After taking your products, I’ve got the energy of a 20-year-old—walking 3–5 miles in the morning, then kettlebells in the afternoon. My focus and productivity have skyrocketed.
I’ve already placed my second order and recommended your products to friends and family. They’ve been a game changer for me.”

Narinder (‘Nins’) Rai


“Thoroughly vetted and recommended by a performance expert.”
“I’m very careful with testosterone boosters. I thoroughly vet, research, and test any product I use. Aggressive Strength satisfies all the criteria: it does what it claims and it’s made by ethical people who know their stuff.
As an athlete, I’ve had to fight low T, low LH, and low libido from heavy training, and Mike Mahler has turned that around. Every hard-charging guy needs a bottle of this in his fridge. I highly recommend it.”

Ben Greenfield, author of Beyond Training: Mastering Endurance, Health, & Life


“From depressed and washed out to PRs and feeling like a teenager again.”
“Stress, training, and entrepreneurship washed me out. No sex drive, low energy, no focus, no ambition. At 32, I felt like an old man.
After starting Aggressive Strength, my concentration snapped back, my productivity exploded, my workouts improved, I hit PRs, gained muscle, and my sex drive and performance went through the roof. I honestly can’t remember feeling this good since I was a teenager. It’s like a new lease on life.”
