I purchased two drugs: hyal-sin prolong-plus for the knee, hyal-sin prolong for the hip joint. Advantages of the company: you can purchase hyaluronic acid preparations at a minimum cost. It is possible to buy halva, halva max, purchase card by installment cards. The discount system works: if you buy again, there will be a 3% discount, then 5%. And there is also an opportunity to get a consultation from a traumatologist (the company has an orthopedic traumatologist on staff).
I bought the drug Hyal-sin prolong plus here for the treatment of arthrosis of the knee joint, the course of treatment is 1 injection, expensive, but very convenient, I injected it once and forgot about the problem joint, I did not bother for more than a year.
I've been buying hyaluronic acid injections for my joints in installments. Pharmacies only give 1 month installments, but here from 2 to 4. Convenient. And the injections are good, they help me.
