Ive been hesitant to post this side effect due to SOOO many issues being rightly/falsely attributed to MT2 use, but after 4 years, I can say with certainty that MT2 causes my joints to ache, including my lower back, hips, elbows, knees, etc... Ive documented the symptoms Ive had over the last 4 years, and many subside after prolonged use, but the joint pain hangs around until I stop dosing. ithing 2 weeks of stopping, most joint pain is gone. Not imaginary. I also stay well hydrated.
Ive done a fair amount of research on the melacortin receptors, and any peptide that acts on 4 receptors isn't "just" tanning you.
I'm only seeing your post now sobol. I too have/had the exact symptoms you describe. I have been using for around the same time as you as well. Particularly notice bruising and inflamation of my knees. I'd list the other symptims/worries but you've seen my thread.
