    Found this product is great for nighttime recovery, even helps with my sleep. Don’t recall after starting this product ever having bad dreams, it seems to stop them which means I’m sleeping more sound.

    I really felt my stack with Testolone was effective with both strength and lean muscle growth. I would recommend it. [Subject] took a capsule in the morning as well as prior to bed.
    Very good customer service and delivery.

    Se nota el aumento del apetito casi desde el primer día. Tomando dos en ayunas no tendrás problemas en tu etapa de volumen.

    Brutal! Un gran producto. Lo uso a 10mg diarios para el control del colesterol después de un ciclo y va perfecto.
    Llega en 10 días aproximadamente súper bien empaquetado y muy discreto 0 problemas en aduanas.

    Awesome results. My research subject has improved in size. This stuff works. There was a lot hunger after taking dose.

  27. 5 out of 5

    Zachary Isaacs (verified owner)

    The conclusion of my study finds that this product does indeed support the natural secretion of human growth hormone in the test subject. Furthermore, it was found through various time trials that secretion elevated before going to sleep promotes muscle hypertrophy while administration after training promoted weight loss. The subject experienced some hunger increase through night administration while much greater appetite increase after training. On the supplier side, the company was very fast in delivery of the tested compound and the price is unparalleled. In all, there is no other company I would recommend for your testing needs.

    Product is amazing! Definitely clean and yielding results. I’ve used pr peptides before they went out, I would say that this product is as good if not better. I like that they come in capsules opposed to liquid. Others I’ve tried prior to this product other then pr peptides did not measure up. Customers service is amazing too.

    Legit MK!

    Usually run between 20-25mg split twice a day with other suppliers so jumped straight in at 30mg for my first Sarmtech bottle which was a mistake.

    My [subject’s] hunger shot up, as did lethargy and insulin resistance as well as a hell of a lot of water retention in the first few weeks.

    Pushed through and sides eventually subsided but I decided to reduce to 15mg once per evening anyway, mainly so I could be a bit more relaxed on my [subject’s] diet without worrying about him going hyperglycemic, and that was definitely the perfect sweet spot.

    For anyone eager to go with the higher dose I would recommend being very strict on diet and/or looking to give your [subject] a good GDA to manage insulin.

    I have noticed that [subject’s] apatite has increased but not the desire for food not on my diet. Havent necessarily noticed improved sleep but [subject has] never been someone that remembers dreams. I have noticed after almost a full bottle that [subject’s] muscles are looking fuller and have noticed a slight decline in belly fat. I just reordered and I am planning on doubling up on [subject’s] dosage to see what this will do on the effects. Good times.
