MusclePharm’s announcement last year of a collaboration with 7 time Mr Olympia Arnold Schwarzenegger brought with it news that 8 new products will be released. This new series of supplements; titled the Arnold Schwarzenegger Series has been one of the most exciting new releases for some time and has dominated the nutritional, sporting and bodybuilding supplement industry. While only 7 supplements have been officially named and released so far, an elusive 8th supplement was said to be in the pipeline. Our original guess was for a testosterone support supplement titled Iron Test as most other categories of supplements have already been covered and lo and behold, 9 months later, Iron Test is finally a reality. Let’s see how it performs.
MusclePharm Arnold Series Iron Test Highlights
- Blend of testosterone support and anti-estrogen or aromatase and 5 alpha reductase inhibiting ingredients.
- Support testosterone levels and control estrogen and DHT levels.
- Forms an excellent stack with Iron Cuts
MusclePharm Arnold Series Iron Test Ingredients & Dosage
The concept of Iron Test was originally pure conjecture and so any previous discussion about ingredients was pure assumption as well. Having seen a variety of testosterone boosters; both effective and not so effective, here is what we thought Iron Test will most likely or should contain:
- Tribulus Extract with Added Protodioscin, Longifolia or Longjack D-Aspartic Acid, Fenugreek, Maca, Horny Goat Weed, Curcumin, Carnitine, DIM, Resveratrol
The new Arnold Series Iron Test is a very simple supplement containing a total of 7 ingredients, 2 of which were in our original assumptions. These ingredients include:
- Vitamin D (400 IU)
- Zinc (as zinc citrate – 30mg)
- Iron Test Blend (1,350mg) – A proprietary blend containing Arginine Nitrate, D-Aspartic Acid (DAA), Testofen (Fenugreek or Trigonella Feonum Graecum), Indole-3-Carbinol and Boron.
Each container contains 45 servings of 2 capsules, however may be available in an additional larger size of 90 serves.
MusclePharm Arnold Series Iron Test Pros & Effectiveness
One of the best things about MusclePharm Arnold Series Iron Test is that the majority of the ingredients have been shown to help support testosterone levels.
- Vitamin D - Levels of vitamin D and levels of testosterone have been indicated to be interrelated1 and with deficiency levels increasing over time, vitamin D is always a good ingredient to have in a test booster.
- Zinc – Similarly zinc levels in the body are commonly related to testosterone levels2 and 30mg a day is a good recommended dose to help maintain adequate levels, especially in people who train regularly.
- D-Aspartic Acid (DAA) – DAA has long been seen as one of the newest range of test boosting ingredients3 and is especially good for people who have lowered initial levels of testosterone.
- Fenugreek – The specific brand of fenugreek used in Iron Test known as Testofen has been shown in a study4 to support improved testosterone levels in resistance trained males thanks to its effect on decreasing testosterone conversion to DHT or dihydrotestosterone.
- Indole-3-Carbinol – A compound which contains DIM or diindolylmethane, a popular anti-estrogen ingredient. Anti-estrogen support is important as increases in testosterone also generally results in increases in estrogen which can negate some of the positive impacts of boosting testosterone levels.
- Boron – A trace mineral that has been shown to increase free testosterone levels, but only on an acute basis5.
MusclePharm Arnold Series Iron Test Cons
As shown above, the majority of the ingredients of Iron Test have definite testosterone boosting abilities. The inclusion of Arginine Nitrate is an odd choice though. While it’s a great pump ingredient, it doesn’t have any testosterone boosting capacity per se. Most likely though, MusclePharm has chosen this ingredient as a way of shuffling the actual active ingredients faster into the bloodstream. The use of a proprietary blend is also a bit old school and makes it a pain to analyse if they’re using adequate amounts.
MusclePharm Arnold Series Iron Test Taste & Mixability
Iron Test is currently only available in capsule form, but may be reformulated into a powder at a later date.
MusclePharm Arnold Series Iron Test Verdict
Overall, MusclePharm’s Arnold Series Iron Test is a fairly well thought out supplement. Minor issues aside, the supplement does include a good list of proven testosterone support ingredients and is a great stack with Iron Cuts, which has added testosterone support ingredients as well. The new Arnold Series Iron Test should please Arnold and MusclePharm fans and offer a decent boost to your training sessions and results.1. Wehr E, et al.
