It works...
5 out of 5 stars
It works...
So I read the reviews, everyone says "It did nothing for me!" Their expectations are not realistic. This is not Viagra with an almost immediate effect. The effect that this provides is subtle. I got this because I am 45 years old and after years of working out with weights I don't see the results that I used to, this was really disheartening for me and after years of sedentary lifestyle I wanted to try again. Initially I was like everyone else. I thought that it was garbage and fake but I kept taking it, due mostly to the fact that I bought it and I may as well see it out. After a few weeks I noticed a difference in my mood and my sexual appetite. I have always been extremely sexual but lately with work and life stress, I could care less. This product brought back a desire that was faint at first and slowly grew over time. It's been a while since I have woken up in the middle of the night with a big hard erection. This stuff has it happening a few times a week now. I don't care what these other people feel. This stuff works, and it works without making you feel nasty, bad or generally not right. I feel natural and normal, give it a chance and don't expect to take two pills and jump up tomorrow turning into Superman. Follow the instructions and don't miss days. I wasn't paid for this, I don't know anyone at this company.

    My Review of Test Worx

    Why I tried this product -

    I was looking for a vitamin/energy supplement to assist with light work-outs and cardio. My energy level was lagging, and I didn’t think I was getting the same out of my work-outs that I was putting into them. Many years ago when had a more arduous work-out schedule, and I used Hot Stuff; a powder mix that is no longer available. It was a remarkable product, and while I tried several others since; none came close. I read several reviews here on Test Worx.

    Many reviewers here wrote compelling articles endorsing Test Worx, but my final decision to try it came after I read one review that was very different from all others. The reviewer mentioned he noticed that his pain medication was working better after he started using Test Worx.

    I found this very intriguing.

    I suffer from moderate to severe lower back pain resulting from a couple of bad discs prone to herniation, and variable stenosis in the same area (a consent pain). This is treated with spinal manipulation, physical therapy (various exercises, and much stretching), and pain medication at times. I also have an icing regime of 20 minutes every morning, and again almost every afternoon.

    So, I turned my attention to wondering if perhaps there was some physiological or even neurological aspect associated with the increased efficacy of the medication the aforementioned reviewer experienced. One such review is very slim to go on, no doubt, but many others were reporting that they began feeling physically great, and one guy even said he felt like Superman (hope he didn’t take an unnecessary ‘leap of faith’).

    What I experienced -

    Now, maybe my posture is more correct due to the gains I have experienced with my moderate work-outs, and that has taken pressure off my spine. Maybe, with the increased energy I have, I am able to do more reps of lower back exercises that strengthen core and provide better support. One thing is for sure, I am in far less pain. Further, I am experiencing far fewer instances of a particular dysfunction that would result from hitting a certain nerve in my back at the wrong time in bed (too many times). And my icing in the afternoons is almost gone (I prep the ice, and wander off doing something else). Also, reduced use of pain medication.

    Seriously.

    Here are a few other things I have noticed:

    •Improved mental acuity (even in the afternoons)
    • Improved energy in the afternoons (now, when I think about doing something I notice I doing it before I’m done thinking about doing it)
    • Improved energy in the mornings (jumping out of bed)
    • Improved sense of smell (especially with women present)
    • Improved muscle firmness (especially in chest area)
    • Increased weight loss/improved tone (stomach, rear saddle bag area)
    I did not have a weight problem, but I’m noticing, and so are others, a general ‘slimming-up’.
    • Increased sex drive (frequency, stamina, performance)

    Caveats:

    • Experienced two instances of being ‘testy’ (advise you do not use your words, but find something to do).
    • Your wife will begin looking very good to you a lot of the time (this may be the best cosmetic she never bought).

    Reviewed:

    After fourth week of use; 60 years old, good shape to start, 3 days moderate work-out with free weights (supported), 3 days cardio (treadmill, aggressive), other physical therapy and conditions noted in review. Intend to continue use of this product for reasons stated in review.

    Disclaimer:

    Observation of first week of product use clouded by contracting an allergy aggravated cold and resulting in use of allergy meds, and second week clouded by recovering from effects of same, and third week obscured by road travel with interrupted sleep pattern (lack thereof). Manufacturer contacted this reviewer with Customer Appreciation offer of one bottle of product if reviewer shared this experience (be advised this customer decided to share review before being contacted). This is not a white-wall clinical study; many other factors may be at play, and no two people, as to conditions or ailments or circumstances, are exactly alike. (I was going to wait until I finished the entire bottle of this supplement before writing this review, but I refer the reader back to points in this review on improved mental acuity and increased energy.)

    Parting Advice:

    Try this product. If you experience acceptable, positive results, stock up! (remember my opening product reference, and draw your own conclusions).

    Report
  • Reviewed in the United States on November 16, 2015
    I'm going to post what's happened to me since I began taking this product and let you draw your own conclusions.

    5 years ago, I could competitively complete a Nissan Xterra triathlon. I had a third child, changed jobs to a much more demanding one, and got 5 years older (38 now). Over the past 5 years, I gained 35 pounds, ate poorly and had little to no motivation/energy/time to make a lifestyle change. I got high blood pressure, a bad back and fattened out of the $5000 dollars worth of suits and shirts that I bought for my new job.I tried dieting, I tried other supplements and very occasionally, I tried exercise that often left me in pain for weeks upon end.

    I began taking TEST WORx about 4 weeks ago. What motivated me to take this product is exactly what motivated me to make major changes in my life. So in all sincerity, I can't attribute all my positive changes to this product, but knowing research, statistics and the simple fact that I've tired everything else (sans TEST WORx) over the last 5 years without success, there's definitely a statistically significant correlation to what I've experienced and use of this product.

    What's happened: In the past month, I've changed my diet, begun working out and lost 15 pounds (which is probably 17 pounds of fat and 2 pounds of muscle gained). I've also used this product exactly as recommended. Obviously, the major difference is going to be from diet and exercise but I stress, it's not like I haven't tried this before. Something's kicked in this time around and I find that there really is an improvement in energy, motivation, desire and recovery time between workouts. I saw immediate changes from my efforts and didn't try something different for a couple days only to get discouraged by a lack of results....therefore, the tradition diet and exercise has stuck. I should note, I'm not taking any other supplements and this is the only thing that's different.

    Knowing research, I could see a cynic saying that this is the result of the worst case scenario....placebo effect, but I don't think so. Only because I've tried other things in the past without results. And even if it were, I'll take the results! There's nothing wrong with placebo effect if it works but again, I don't think this is the case and if anything can be certain that this product definitely doesn't hurt!

    Last week, I went running for the first time in 5 years. I've used my bike a few times since then and can always spend a day in a city walking multiple miles. However, running hasn't interested me much since I started having back and knee pain a number of years ago. I figured I'd still give it a try and managed to run 5 miles without stopping my first time out. At no age (18, 21 or 37), I couldn't go more than 2 miles my first time in a while. I truly can't explain this.

    In conclusion, I've lost major weight, feel younger, better, have more energy and am motivated to eat well and work out for the first time in many years. I fit in my clothes again after one short month and the diet and exercise has not been hard. It's like my body knows that I don't need all the calories I usually take and has learned to burn the plenty of stored fat I have for it's energy. As far as exercise, I don't need a week to recover and am excited every day about my next work out. I recommend this product to anyone who is just looking to try something new to achieve results in their lifestyle changes and health. You just might be surprised!
