I've brought my mk677 from a very reliable and trusted source. And it did seem to work but I had some issues like sensitive nipples and a clear fluid if squeezed very hard after only 6 capsules of 10mg on 2 days on 1 day off protocol. So I stopped it, it's been more than 2 weeks. As SLIN pills were out of stock, I stacked Glucose Disposal Stack with it. Now I've migitated the effects of probably high prolactin or E2 levels using B6 P5P 50mg capsule. I'm thinking to start the cycle again but with 1 day on 1 day off protocol alongside GDA, B6 p5p and berberine hcl 500mg.
