The treatment with the strongest evidence for most tendon problems is not a pill, an injection or a machine. It is progressive loading: a structured exercise program that gradually puts more weight through the tendon over 12 weeks or more. Shockwave therapy has moderate evidence for some tendons. Cortisone shots relieve pain fast but can make long-term outcomes worse. PRP results are mixed.
BPC-157 and TB-500 are the peptides people search for, because rat studies show faster, stronger tendon healing. Human trials have not been done. Here is every option ranked, with what it costs in Canada.
Tendonitis vs tendinopathy: why the name matters
“Tendonitis” means an inflamed tendon. But when researchers looked at tissue from long-standing sore tendons under a microscope, they found very few inflammatory cells. Instead they found disorganized collagen, abnormal blood vessels and failed repair. That is why clinicians now prefer the word tendinopathy.
The distinction is practical. If the problem is mostly failed repair rather than inflammation, then treatments aimed only at inflammation (rest, ice, anti-inflammatories, cortisone) will calm pain without fixing the tissue. Treatments that stimulate repair, especially loading, address the actual problem.
Why tendons heal so slowly
- Poor blood supply. Tendons have far fewer blood vessels than muscle, so fewer repair cells and nutrients arrive.
- Slow collagen turnover. Tendon collagen is replaced very slowly compared with skin or muscle.
- Constant use. You cannot fully rest an Achilles tendon or a rotator cuff while living your life.
The practical result: meaningful tendon healing is measured in months, typically 3 to 6 and sometimes a year for chronic cases. Anything promising to fix a tendon in days deserves skepticism.

The treatment scorecard
| Treatment | Evidence | Short-term pain | Long-term healing |
|---|---|---|---|
| Progressive loading | Strong | Gradual | Best |
| Shockwave (ESWT) | Moderate, tendon-dependent | Moderate | Good for some tendons |
| Cortisone injection | Strong (for short-term) | Fast relief | Can be worse |
| PRP | Mixed | Variable | Uncertain |
| NSAIDs / ice | Moderate | Helps pain | No repair benefit |
| Surgery | Case-specific | Recovery period | For failed conservative care |
| BPC-157 / TB-500 | Animal only | Unknown in humans | Unknown in humans |
Progressive loading: the treatment that works best
Tendons respond to load. When a tendon is carefully stressed, its cells produce new collagen and gradually reorganize it in the direction of force. The classic study: in 1998, Swedish researchers had people with chronic Achilles tendinopathy who were waiting for surgery do eccentric heel drops (lowering slowly on the injured leg) for 12 weeks. All 15 returned to their previous activity level without surgery (Alfredson et al., 1998).
Since then, programs have broadened from eccentric-only to heavy slow resistance and staged programs that start with isometric holds (which can reduce pain) and build to heavier and faster movements. The common thread:
- Some discomfort during exercise is acceptable, as long as pain settles by the next day.
- Load increases gradually over weeks.
- Programs run at least 12 weeks.
A physiotherapist can tailor the program to the specific tendon, which matters: the right exercise for a sore patellar tendon is different from the right one for a rotator cuff.
Shockwave therapy (ESWT)
Extracorporeal shockwave therapy sends pressure waves through the skin into the tendon. It is thought to stimulate repair and reduce pain signalling. Evidence is best for calcific shoulder tendinopathy and plantar fasciitis, and reasonable for Achilles and patellar tendinopathy when combined with loading. It is uncomfortable but not damaging, and is usually given over 3 to 5 weekly sessions at physiotherapy clinics.
Cortisone injections: fast relief, long-term cost
Cortisone (corticosteroid) shots are powerful anti-inflammatories, and they often relieve pain within days. The problem showed up in a large review in The Lancet: for tennis elbow, cortisone beat other options at 4 weeks, but by 6 and 12 months people who had cortisone did worse than those who had a wait-and-see approach or physiotherapy, with higher relapse rates (Coombes et al., 2010).
Repeated cortisone shots into or near weight-bearing tendons like the Achilles are also associated with weakening and rupture, which is why most clinicians avoid them there. Cortisone still has a role, for example short-term relief to make rehab possible, but it is not a repair treatment.
PRP injections
Platelet-rich plasma uses a concentrate of your own platelets, which carry growth factors, injected into the tendon. The idea is compelling; the results are mixed. A well-known trial in Achilles tendinopathy found PRP was no better than a saline injection when both groups did eccentric exercise (de Vos et al., 2010). Results in tennis elbow have been more positive in some studies. Part of the problem is that PRP is not standardized: platelet concentration and white-cell content vary by system.
Anti-inflammatories and ice
Ibuprofen, naproxen and ice can reduce pain in the short term. They do not repair the tendon, and some animal research suggests heavy NSAID use might slow tendon-to-bone healing. Reasonable for flare-ups; not a treatment plan.
Surgery
Surgery is reserved for complete tears and for tendinopathy that has not improved after 6 to 12 months of well-run conservative care. Recovery takes months, and rehab afterward is still built around progressive loading.
BPC-157 and TB-500: what the research shows
This is why many people land on this page. Two research peptides come up constantly in tendon discussions.
BPC-157
A 15-amino-acid peptide derived from a gastric protein. In rats with surgically cut Achilles tendons, BPC-157 improved functional, biomechanical and microscopic measures of healing compared with controls (Staresinic et al., 2003). In cultured tendon cells, it increased cell outgrowth, survival and migration (Chang et al., 2011), and increased growth hormone receptor expression (Chang et al., 2014). The proposed reason is that it encourages new blood vessels in tissue that badly lacks them.
TB-500
A synthetic fragment of thymosin beta-4, a protein involved in cell migration and actin organization. Thymosin beta-4 has been studied in wound, heart and muscle repair in animals, and it is often researched alongside BPC-157 on the idea that they target different steps of repair.
None of this has been confirmed in controlled human trials. Neither BPC-157 nor TB-500 is an approved treatment in Canada, both are banned in tested sport, and Health Canada has warned against injecting peptides bought online. The rat data are a reason for research, not proof that they heal human tendons. For everything we know, see what is BPC-157? and BPC-157 vs TB-500.

Treatment by tendon
| Condition | First-line | Next options |
|---|---|---|
| Achilles tendinopathy | Heel-drop / heavy slow loading program | Shockwave; avoid cortisone |
| Patellar tendinopathy (jumper’s knee) | Isometrics, then heavy slow squats | Shockwave |
| Tennis elbow | Loading program, brace, time | PRP; cortisone only short-term |
| Rotator cuff tendinopathy | Shoulder strengthening | Shockwave for calcific type |
| Plantar fasciitis | Calf and foot loading, footwear | Shockwave |
Costs and coverage in Canada
- Family doctor or sports medicine physician: covered by provincial health insurance.
- Physiotherapy: public coverage is limited and varies by province (often restricted to seniors, youth or post-hospital care). Most people pay privately or through extended health benefits.
- Shockwave: usually billed per session at physio clinics; often reimbursable under extended health benefits as part of physiotherapy.
- PRP: rarely covered; typically several hundred dollars per injection.
- Imaging: ultrasound and MRI are covered when ordered by a physician, but wait times for MRI can be long.
Mistakes that keep tendons injured
- Complete rest. Tendons weaken without load. Relative rest (reducing aggravating activity) plus rehab beats doing nothing.
- Stopping rehab when pain fades. Pain improves before tendon capacity does; quitting at 4 weeks is the classic route to relapse.
- Chasing quick fixes. Repeated cortisone shots and stacking passive treatments without loading.
- Jumping back too fast. Returning to sprinting or jumping before the tendon tolerates heavy load.
- Ignoring the cause. Training spikes, footwear, technique or certain antibiotics (fluoroquinolones) can all contribute.
FAQ
Tap a question to reveal the answer.
What is the fastest way to heal tendonitis?
There is no shortcut that skips tendon biology. The best evidence supports a progressive loading program run for at least 12 weeks, with shockwave as an option for some tendons.
Should I rest a sore tendon completely?
No. Reduce the activities that aggravate it, but keep loading the tendon with controlled exercise. Complete rest weakens tendons.
Is a cortisone shot good for tendonitis?
It relieves pain quickly, but for tennis elbow, long-term results were worse than physiotherapy or waiting. It is generally avoided for the Achilles tendon because of rupture risk.
Does BPC-157 heal tendons?
In rats, BPC-157 improved healing of cut Achilles tendons. There are no controlled human trials, so it is not known whether it heals human tendons. It is not an approved treatment.
How long does tendinopathy take to heal?
Usually 3 to 6 months with consistent rehab, and up to a year for long-standing cases.
Is shockwave therapy covered in Canada?
Not by provincial plans in most cases, but extended health benefits often reimburse it as part of physiotherapy.
