Has the condition been medically diagnosed as osteoarthritis?
If so, then the treatment plan from the doc would be better than these peptides.
If not, then I have had tremendous relief (when overreaching/overtraining) with Cissus quadrangularis. This plant contains potent anabolic steroids actually, 3-ketosteroids like testosterone (but not androgens nor 3-keto-4-androstan-3-ones; just 3-ones), and are potently bone anabolic & antiinflammatory. However, this was a band-aid; and I did a lot better by getting my training volume down to reasonable levels. Remember, training stress is "hormetic," has an inverse-U shaped curve (an optimization or "Goldilocks" problem; not too little or too much, but just right).
