    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 very surprised at how well this actually works. Makes the test subject feel energetic like the old Adderall days… Endurance has been dramatically increased.

    Brutal. No difference. Doubled, then tripled dosage, still nothing.

    Although energy levels were not through the roof, this product will be tested again with different dosage.

    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 !!!
