PT-141 (bremelanotide) works through the MC4R pathway in the brain rather than the vascular system, offering an alternative for men who do not respond to PDE5 inhibitors. Here is how it compares.
PRP injections usually help for 6 to 18 months: about 12 to 18 months for mild to moderate knee osteoarthritis, 6 to 12 months for hair and 6 to 9 months for facial skin, while healed tendons can stay improved for 2 years or more.
PRP injections for knee pain: clinical evidence for osteoarthritis, meniscus tears, and ligament injuries. Kellgren-Lawrence staging, comparison to cortisone and hyaluronic acid, procedure details, cost, and recovery.
Everything you need to know about stem cell therapy: types of stem cells, conditions treated, what the research shows, costs, risks, and how to find a qualified provider.
Ketamine therapy uses low doses of ketamine, as an IV infusion or the esketamine nasal spray Spravato, to treat treatment-resistant depression, suicidal thoughts, PTSD and some chronic pain. In a 2013 trial one infusion produced a 64 percent response rate versus 28 percent for placebo.
Oral collagen is partly absorbed as small peptides and improves skin hydration and elasticity in randomized trials, but the studies are small and often industry funded. Few longevity supplements have human outcome data, and CoQ10 in heart failure has the strongest.
Nerve pain treatment ranges from gabapentin and duloxetine to regenerative options like PRP, LLLT, neurofeedback, and ketamine, each with different evidence.
Exercise with oxygen therapy (EWOT) pairs 15 to 20 minutes of exercise with breathing 90 to 95% oxygen. Research supports short-term performance effects, while claims about energy and chronic illness remain largely untested.
Cold laser therapy (LLLT, photobiomodulation) uses low-power red and near-infrared light to ease pain and inflammation. The best evidence covers neck pain, knee osteoarthritis, tendinopathy, oral mucositis and pattern hair loss.
To find cryotherapy near you, shortlist local centers, then keep the ones that screen your health first, keep a trained operator with you throughout, and monitor oxygen in nitrogen-cooled chambers.
The vagus nerve is connected to autoimmune disease through the inflammatory reflex, which signals immune cells in the spleen to make less TNF. Low vagal tone is reported in RA, IBD, lupus and MS, and the FDA approved an implanted vagus nerve stimulator for rheumatoid arthritis in July 2025.
You have SIBO and were told to try a low FODMAP diet, but the conflicting advice is overwhelming. This practical guide cuts through the noise with clear, evidence-based food lists and meal plans you can actually follow.
