You have to have a lot of self control if your planning on using a compound like Deca to help heal injuries. @Cheapshot - if it isn't clear I am agreeing with you.Definitely no quick fixes. I was 2 years healing a tendon and still didn't trust it 2 years later. I think sorbqte mentioned it earlier, but the problem I found with deca is i thought everything was fine and i was back to normal, just to realize i was just masking the pain and making it worse. Its a slow process.
Several steroids are used in severe cased to hasten recovery from bad injuries - a cut and paste from a site, "These medicines help to rebuild tissues that have become weak because of continuing illness or serious injury." Will deca help heal a tendon - can't say but it will help heal a lot of tissue.

If I had more time I would search for some of the write ups on actual usages (mostly read about oxandrolone and deca but I can't use anavar). Regardless, can it help with specific injuries - suspect it can and will. Will it help most people, no because they won't have the patience or self control to use it as a medicine and not to build large/strong muscles.
This is from 3 years ago and was a log I ran trying to deal with a host of chronic and some acute injuries / issues: https://www.canadianbrawn.com/threa...njuries-gh-peptides-and-test-nandrolone.3596/
I learned a lot and I would do it different if I did it again but the key to this working was going to physio, seeing my doctor, massage, foam rolling, stretching, very light weights (as if I didn't even work out at times) but using the principal of progressive overload to heal. Not progressive overload like we think for BB - it might be after a few workout outs floor pressing 5 lb dumbbells, I would move to 10 lbs and lower my reps adding in a few reps each workout. A controlled load on the injury. I am not a doctor or sports therapist but hurt myself more times than I care to disclose so take my writing for what it is - opinion. Some injuries you simply can't do this to but in my case I had a lot of chronic issues - no serious acute tears or injuries.
Was it the low dose deca, TB500, BPC157, or low dose Serostim that helped me heal - not sure but I am 100% certain BPC157 healed my Achilles tendons quickly. I suspect it was a combination of different modalities of therapy, some of the items mentioned working together and working out with the one goal of healing - not getting stronger or bigger. Keep in mind I did not have a total tear like you do @DeepInDaBush so your plan will be different.
If you read the log and it is boring - you will see I did grow a lot more than I thought I would but keep in mind a cycle for me is TRT plus 100 mg of Primo so adding in 150 mg of deca and 2 IU of Sero is like throwing gas on fire. I was off all PED's for a very long time when I did this.
I used low dose deca to help heal some of the issues and I suspect it worked but I am in my 40's and have been throwing around iron for decades, I know the difference between good pain and bad pain and am willing to stop in the middle of any workout and walk out of the gym and reassess the next morning. 3 steps forward, 2 back, etc.
Unless you have a sensible game plan and will stick with it - I wouldn't use deca to heal a tendon.
