Quick Take: In sports, mastering the fundamentals is key to being a successful athlete. Take Tim Duncan and Kobe Bryant for example. This same concept can be applied to testosterone boosting. With Iso T-Drive, it looks to have a lot of these T boosting fundamentals covered but when it comes to mastery? Probably not. Check out the review.
- Manufactured by Advanced Nutrition Systems, Iso T-Drive is a testosterone booster under their Men’s Health category
- Advertised to be a “powerful testosterone booster designed to boost natural testosterone levels”. It’s really not that powerful though.
- Has Zinc and Calcium. Individually healthy and beneficial for T but not a good combo.
- Packed with potent herbal extracts that all take different routes at promoting male health
- Generally low dosed which undercuts the supposedly manly potential of its ingredients
- Available to buy online and in retail stores including GNC and Walmart. Surprisingly, I couldn’t find it on Amazon.

Advanced Nutrition Systems Iso T-Drive’s T-Boosters & Other Ingredients
Vitamin B6 – As Pyridoxine HCl, this isn’t actually its best form but as rat research suggests, maintaining healthy levels of this manly vitamin may be essential to maintaining healthy levels of testosterone and at 5 mg, it does seem manageable.
Calcium – It’s somewhat common knowledge that exercises boosts testosterone. What you probably didn’t know is that according to research, this exercise-induced boost in test seems to be bolstered even more with calcium supplementation. You’re likely going to get more calcium from a cup of skimmed milk than from Iso T-Drive though.
Zinc – In this picolinate form, Iso T-Drive has a potent version of Zinc. This mineral serves as a raw-material in testosterone synthesis and is therefore, important for healthy levels of testosterone.
There’s a twist in combining Zinc and Calcium supplements though
What’s the twist?
As I’ve said, both Zinc and Calcium have their own benefits on testosterone. However, combining both of them might actually be counterproductive as both of these minerals share the same absorption sites and therefore compete with each other.
As stated in a study, “high-calcium diets can reduce net zinc absorption and balance and may increase the zinc requirement in adult humans”. That said, despite having an easily absorbed Zinc Picolinate, with just 3 mg, there’s very little Zinc to absorb here in Iso T-Drive. Combining this meager dose with Calcium most probably renders it useless.
ISO T-Drive Complex
- KSM-66® – Ashwagandha is an adaptogenic herb that effectively reduces levels of stress (cortisol) and supports muscle mass and strength. As branded KSM-66, however, it’s made even better as research shows it’s also capable of boosting testosterone. Ideal for bodybuilding enthusiasts and active men.
- Tribulus terrestris – Potently standardized for 40% saponins, Tribulus Terrestris isn’t actually a testosterone booster despite being heavily marketed as such. It’s pretty good for libido though.
- Magnesium D-Aspartic Acid Chelate – This powerful amino acid has shown capable of boosting T by as much as 42% in just 12 short days and this chelated form, it should be absorbed that much easier.
Oat Straw – Heavily concentrated at this 20:1 extract, this is popular in nootropic stacks for improving cognition but it also has NO boosting benefits which may make your workout pumps better with improved circulation.
- Saw Palmetto – Offers prostate protection from 5-alpha-reductase inhibiting effects. This also makes it potentially capable of increasing “free” testosterone via DHT reduction.
- Milk Thistle – Ask your bodybuilder friends who’re taking steroids or prohormones what they take to protect their liver from failing and they’ll probably answer Milk Thistle.
- Diindolylmethane (DIM) – Derived from cruciferous vegetables, this compound inhibits aromatase – the enzyme responsible for converting testosterone into estrogen. Theoretically, this lowers the notorious female hormone while sustaining higher levels of “free” T.
Advanced Nutrition Systems Iso T-Drive Directions
Each serving of Iso T-Drive consists of 2 capsules and as instructed by Advanced Nutrition Systems, adults are to take 1 serving (2 capsules) only once per day.
Ingredients-wise, Iso T-Drive has an effective set not just for boosting testosterone, but also for regulating other related hormones as well as bolstering sex drive and physical performance. On paper, this should make for a really good supplement stack. However, there are a few issues that prevent this from happening. Let’s start with the vitamins and minerals.
In the V&M’s department, Iso T-Drive has Vitamin B6, Calcium, and Zinc and all of them have their individual benefits on healthy testosterone. Among these 3 though, only B6 might have an impact as both Zinc and Calcium have puny dosages. Couple that with how they essentially cancel each other out and, well, they’re probably useless. These are just the undercards though. The main attraction is the Iso T-Drive prop blend.
The ISO T-Drive Complex consists of 7 ingredients (mostly herbs) that have either hormonal or non-hormonal benefits on male health.
- On the hormonal end, KSM-66®, DAA, Saw Palmetto, and DIM all work in unison to boost testosterone while lowering levels of cortisol, estrogen, and DHT. In effect, this also makes for an anabolic internal structure that’s suitable for growing muscles.
- On the non-hormonal benefits, Iso T-Drive supposedly targets libido as well as cognitive and physical performance with Tribulus, Oat Straw, and Ashwagandha. Plus, there’s the added prostate and liver protection from Saw Palmetto and Milk Thistle.
Sounds good, right? Sure. But here’s the problem:
Again. Like the V&M’s, the Iso T-Drive prop blend also struggles with milligrams. Fortunately, some of the herbs here are given in top-shelf qualities and should therefore, lower the required dosage. However, with just 945 mg of total dosage, Iso T-Drive might still not have enough goods to make all of its 7 ingredients happy.
Does it Work?
Well, there’s enough Vitamin B6 to mildly support healthy levels of testosterone but when it comes to the ISO T-Drive Complex, I can’t be sure to what extent.
Hypothetically, Iso T-Drive is capable of elevating T while also lowering estrogen, DHT, and cortisol along with boosts in libido, muscle mass and strength. However, because the prop blend doesn’t actually disclose the individual dosages of its ingredients and because of the low total dosage, I can only assume that while Iso T-Drive hits these benefits, it doesn’t necessarily hit deep.
- Quality – A lot of the ingredients here get premium, easy-to-absorb forms
- Prostate and liver protection – I’d like to see more products have these benefits
- Safe – There aren’t a lot of customer reviews to verify it but an all natural formula like this should be free of any major side effects.
- Proprietary – Why’s it so hard for some manufacturers to just show ALL their dosages?
- Dosage – Speaking of dosages, Iso T-Drive doesn’t have enough
- Poor combination – Specifically, Zinc and Calcium
- “Other Ingredients” – Gelatin, Magnesium Stearate, Silicon Dioxide, FD&C Red #3, Titanium Dioxide, FD&C Yellow #6, FD&C Red #40, FD&C Blue #1. All these are junk.
- Expensive – Prices vary but wherever I see Iso T-Drive being sold, it’s somewhere around $100
The Bottom Line
If all of its ingredients work, Iso T-Drive hits multiple angles of male health which, of course, includes boosted testosterone. The problem is that despite having generally potent ingredients, Iso T-Drive also generally lacks in the dosage department. To be fair, I do think it’ll still have benefits but I wouldn’t classify it among the elites of the industry.
