What About MK-667?
While it's not a SARM – it's an orally effective peptide – it's often put in the same boat because it's sold at the same places and is taken orally (most other peptides are taken by injection).
MK is by far one of the worst products you can take, at least in "normal" doses. It works mostly by increasing growth hormone production, but it increases it for too long, giving you tons of pulses over a 20-24 hour period. As such, it decreases insulin sensitivity really quickly and it will also bloat the f**k out of you. You'll gain 10 pounds of water overnight and look like a water buffalo.
It'll make your blood pressure skyrocket too, and it can inhibit your natural growth hormone production because of its super long action.
