DS will be 15 in a few weeks and has been diagnosed with delayed puberty after lots of investigations. He has been prescribed testosterone injections of Sustanon 250 and had the first one today. Does anyone have experience of this and can tell me how long it will take to see/feel changes? The second reason I'm posting is because there is very little information online about getting a diagnosis/what's involved - I spent hours Googling without a great deal of success and I thought it might help other people. If anyone has any questions about it feel free to ask!
