Thanks for sharing your story,what a rough year you've been through. Pelvic fracture, femoral necrosis, total hip replacement, and now osteopenia on top of it. Let me try to address both your pain/mobility question and the bone density issue, because they're both important.
On BPC-157
Yes, it's worth considering given your situation. BPC-157 has shown consistent results in animal models for tendon, ligament, and bone healing, as well as analgesic and anti-inflammatory effects. For musculoskeletal recovery like yours, subcutaneous injections near the affected area (200–500 mcg/day) are the typical approach. It won't correct the structural leg length discrepancy, but it may help reduce chronic inflammation and soft tissue pain around the hip and pelvis that's likely contributing to your discomfort. TB-500 (Thymosin Beta-4) is often combined with BPC-157 for musculoskeletal recovery and may add additional benefit. Access in the UK requires private sourcing, and human clinical data is still limited, so go in with realistic expectations.
On Osteopenia. Don't Overlook This
Honestly, the bone density issue deserves as much attention as the pain. The good news is that as a long-term TRT user, you have some built-in protection, testosterone plays a real role in maintaining bone density. But that only works if your levels are well-optimized. Make sure your total T is solidly above 500 ng/dL and that your estradiol isn't being over-suppressed, since estrogen is actually critical for bone in men too.
Regarding Profilio: that's primarily a polynucleotide skin/collagen treatment, and its use for osteopenia seems unusual to me. I'd seek a second rheumatology opinion before going that route.
More established approaches for your situation:
- Vitamin D3 + K2 (MK-7): Many TRT users are deficient in both. D3 at 5,000–10,000 IU daily with K2 (100–200 mcg MK-7) is a reasonable starting point. Get your 25-OH Vitamin D levels checked.
- Magnesium:Often overlooked but essential for bone metabolism.
- Bisphosphonates (e.g., alendronate):If your T-score warrants it, this is a well-established first-line treatment worth discussing with your doctor.
- **Teriparatide or Romosozumab: If bone loss is more significant, these newer agents actually build bone rather than just slow its loss, worth asking a specialist about.
On the Leg Length Discrepancy
If you haven't already, please see a good podiatrist or orthopedic specialist specifically about a shoe lift or custom orthotic. A one-inch discrepancy creates significant compensatory strain throughout your pelvis, lower back, and hip..which may be a major driver of your ongoing pain and the feeling of pelvic distortion you describe. This is a simple, underutilized fix that can make a meaningful difference.
On Exercise
I completely understand the frustration with the gym. But resistance training ,even modified, remains one of the most powerful tools for bone density. If traditional lifting is off the table right now, consider pool-based resistance work or seated/chair exercises. Even low-load mechanical stress on bone matters.
Hope this helps point you in some useful directions. Keep working with your physio and don't give up on the gym, just adapt it to where you are right now.
