    My lab subject turned from being unable to run a mile, to running several miles then riding a bike for even more miles. My lab subject also got very lean from this. I highly recommend your lab rat try this

    Presumably, the suggested use for this is for cardio/fat loss.

    As someone who’s known to watch his pennies…this product had me concerned, due to the short half-life, and needing to take them every 4 hours. That’s …damn often, for folks who are busy! So, do they work? I think they do. I can’t say how much because when you’re in a calorie deficit, you’re going to lose weight. It’s really tough to say how much of an impact they have.

    But, when you’re trying to improve your fitness, you reach a point where you have to go for tiny, marginal gains and hope they add up to something measurable. In the case for my reserach, they have. I cannot say how much is from this product, but I believe it’s had some impact.

    I’m no fan of needles, so I’m not measuring anything in lab subject’s blood, before or after. I can say I stopped adminstration for the past 2 months out of concern for natural testosterone levels (there are warnings about that if you use continuously), and I am fairly certain the lack of them has been evident in the lack of progress, despite all other things being the same.

    Bear in mind, I have been administering with multiple SARMs in a stack, so tough to say which is doing what.

    Like the Light blue Stenabolic, these are for cardio/fat loss. The two together seemed to help me – but I thought it could easily be one doing everything, and the other doing nothing – except for the fact I started subject taking Stenabolic alone, then later combined the two, then stopped taking the Stenabolic due to the every 4 hour suggested use. It’s my anecdotal experience that suggests separately, an impact can be determined, but it’s hard to notice, particularly if everything else – diet, sleep, etc are in check. But combined, when sleep isn’t that great, that’s when I noticed performance having a slight upward trend. Based on that – I say get both.

    I am 76 year old male GW-501516 absolutely improves my research subject’s ndurance and leans without losing lean body mass – it is not a stimulant , however, its really
    makes a noticable difference in Endurance on the bicycle , or doing higher rep resistance
    work – I am impressed – I can do 20 reps in Pull up from dead hang ! and my body fat is
    most likely under 10% at 76 year of age – I cycle ON and OFF , check YOU TUBE for more
    info on various protocols – It is really rather amazing supplement !!!

    on my 4th day of research with this stuff and i can confidently say i can tell a difference in cardio. Subject has only been running 3 miles since starting but today was the the day i noticed that the 3 miles was pretty easy for not running in over 2 months. only reason stopped at 3 miles was cause my phone was acting up and wasnt tracking my miles during the run :/ other wise subject would have gone for 5 !

    Best non pre-workout out there. The stamina and energy boost is unmatched. This is commonly used on a cutting stack, however it can be used on a bulking stack as well.

    I am 6 weeks into my Cardarine stack with Ostarine and couldn’t be any happier. My [subject’s] body fat is down 4% but weight is up 7 lbs. Cardio is super easy and [subject] can do an hour of circuit training plus 45 minutes of cardio and not get tired. [Subject’s] mile run time is also down 2 minutes in 6 weeks and this stuff is legit. I am going to run this 6 more weeks take a month off then run it for 12 weeks in the spring!

    This is the best company that I found among many SARM manufacturers to provide research capsules with the best quality.The company’s products are always 100% satisfactory in terms of quality control! You won’t be disappointed, other than that; my personal favorite is their way of earning points every day by signing in, and points can be used to deduct money during purchase settlement. I will continue to shop at SARMTECH.

    Cycled at 10mg/day with RAD 140 at 15mg/day for six weeks for an absolutely incredible hypertrophy phase. The strength and mass increase from the RAD combined with the stamina and endurance of the Cardarine makes set last forever. If you shoot for a set of 12, get ready to do 20. [Subject] found it difficult to reach muscle failure on nearly any set.

    Really incredible product. And sarmtech is the best combination of affordability, quality and customer service. I’ve referred two of my friends and will continue to do so!

    Was referred to this site by a friend and SARMTECH beat my expectations and outperformed any other sarms source I have done business with! Cheap and quality don’t normally coexist but here they do, and you can’t beat free shipping in the U.S. my package came 3 days after purchased! I’m excited to do some research and see how my lab rat reacts, I will repost with results.
