Biolab Fluid GF™ is injected directly into the painful and inflamed joint where it cushions, lubricates, and protects the joint structure. Since Biolab Fluid GF™ is in a flowable form that is easy to apply, pain and discomfort are minimal. It is a good alternative to Platelet Rich Plasma for those who are not candidates for that treatment (people with bleeding disorders, low platelets, cancer patients).
