These are the sort of things that research would have told you had you done some before you started using steroids.
Steroids do not weaken tendons. Increased muscle contractile strength puts excessive strain on tendons. They are not weakened but rather they are not able to keep up the the rate of strength increase and growth of muscle fibers that one can achieve using steroids. This is also a very common ailment for those who have never trained very much or very well before using steroids. They never developed tendon strength in the first place and then they use steroids.
Well-said,
B! The world would be a better place if more folks would heed the knowledge and experience you bring.
The whole "Get HYOOGE fast!" thing gets to be an obsession, but you have to remember to keep things appropriate: tendons take time to gain the strength & mass necessary to stand up to the strain of moving massive weight - and by "time", I mean weeks and months of being subjected to slow loads. Deadlifts and farmer's-carry are king here (sound off if I've missed something obvious), but rather than increasing your weight as your muscles get used to it, try slowing them down instead.
Important to remember that ligaments take longer to adapt than tendons, just as tendons take longer than muscles - and they take MUCH LONGER TO HEAL once they're damaged...just as tendon injuries take much longer to heal than muscles (has to do with blood supply, if you're interested).
This is perhaps the BIG reason I do not lift to failure.
The takehome is: if you actually want to transform your body, you have to work WITH your body and its mechanisms - that takes TIME, and *that* requires focus, discipline and persistence; it's a lifestyler's gig, dabblers & dilettantes should not try this, at home or elsewhere: if you "just want to get fit", yard-work and portion control will go a long way for you!
Anyhow, that's some stuff I learned.
