I started on Reandron 1000 (Aussie name for your Nebido). Libido, genital sensitivity & growth, body hair changes were pretty stock standard - first changes within the first weeks to month. First voice drop at about 2-3months from memory which once again is about "normal" for any T..
I haven't noticed any real differences between my 1000 every 6-7 weeks (at my GPs instruction for now, my body uses the T very effectively & I am closely monitored) & the regular 100-250 per week/fortnight. I don't really get the up & down I've heard others describe - except for the first few injections where my body was still getting used to it..
I suppose it feels like a couple of my changes have been slower than others - like my arm hair is only now at like 55 weeks on T is becoming noticeable & darkening/lengthening etc, but I don't know what is normal! No one really talks about arm hair! I was a pretty hairless wonder before T!! I have plenty of hair everywhere else & that all happened pretty fast. Lots of hair on my chin & moustache area & now creeping up my neck & sideburns...
The only real pain is it has to be injected in ur glute as it is 4mls! It just makes it a little hard to inject yourself.. I mean I can do one side with ease but have to get a friend to inject me in my non dominant side

But I too get the little lump & ache for a few days - even though usually the shot itself doesn't hurt or stings a little.. But it goes away & obviously as we all know - its worth every second of discomfort!!
JohnR I have a youtube channel with vids of my changes etc on Reandron/Nebido if you're interesed
