I think the issue with Cortisone may be that it has the ability to "mask" any tendon damage.
This is all hypothetical but, since cortisone can induce the "fight or flight response" it should in theory provide a better pump in the gym.
I don't think it causes tendons to weaken if used short term but, due to its ability to suppress the immune system, it can hide any damage done.
So usually when you train hard in the gym if you feel pain you tend to address it in some form right? The cortisone can hide the pain to an extent by suppressing the immune system so by the time you realise you've weakened your tendons its too late.
This might also explain why Dorian blamed the cortisone for weakening the tendons - his training weakened his tendons but because he didn't feel it like normal he couldn't address it.
I think one of the differences is probably the fact when you combine cortizone with testosterone it might have a reaction and make tendons weaker or give you more water retention. Than if you were to take either substance alone. Im pretty sure cortizone doesn't have any anabolic or androgenic properties. Also I just realized cortisone and cortizone are to different things. So I think you are talking about the cream I was thinking you were speaking of the injection. Sorry about that.
I think chronically it may and may have seen a reference to it. I'm not ready to be quoted on this lol but I will see if I can find the reference. In either case your point still stands, it can mask other issues leading to indirect damage.
Great post.
Catabolic hormones are catabolic...
I think the reference your looking for had something to do with tennis elbow? It showed that cortisone only had short term positive effects on tendons and was, ultimately, detrimental long term to tendon strength.
It's mentioned in this analysis also - http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3435934/pdf/10.1177_1941738112440957.pdf
As others have said, Cortisone has effects that are very unlike (almost opposite) anabolic steroids.
They have anti-inflammatory effects that have more of a masking than a therapeutic effect on injuries.
They are often banned in sports not because they enhance performance, but because they can be abused to allow an athlete to compete while injured, ultimately detrimental to his health.
good to hear about Dorian Yates, but testosterone can have a similar effect on the tendons, your muscles will grow but the tendons will weaken, I think I'm right so what is the difference?
Very well could be, it's been so long. Your thoughts are that acutely it's not damaging but chronically it MAY be damaging either directly or indirectly?
