I have just started taking Growth in the last 6 weeks so limited personal experience but I have done my homework so.....
In theory Growth should aid in bone growth. As you probably know Growth's primary function is in multiplication of cells therefore it should help
IF this is the cause of your pain rather than latent nerve damage or a host of other conceivable problems post car accident.
A couple of things to consider - GH is a long process, you either buy in for 6 months plus or it is a waste (not including those who take it while on a steroid cycle for synergy purposes)
Growth is very expensive so bearing in mind the above I would carefully consider it - also you mentioned you are not working at the moment you might be a millionaire of course
I don't think any by-the-book doc will prescribe growth for you for this and even if they did it will then be even more expensive.
Regarding the query as to which is more "healthy" steroids or growth, well that one has just too many variables - dose, quality, your individual bodies reaction to each et. etc. etc.
For eg;
If you were running small dose (say,
>500mg) pharma grade testosterone and had all the ancilliaries needed V's pumping 15 i.u. Growth into you each day well then the test will probably cause you less of a problem and you will probably start looking like you are trying to reverse evolution and return to the trees on the growth.
However running sensible doses and all other protocol there is really no definitive answer - probably less troublesome sides on low dose Growth
Hope this helps a little
