Don’t worry too much about the scale weight. Focus on how you look and how you feel.
You’re very young and just starting your journey. If you keep at it, and do things right, you will see continued growth and progress. When looking at photos of other people, you must remember that: they may have many more years of experience, they could train harder, the could have a better diet, they could have better genetics. As individuals, we are all unique. Understanding and following the fundamentals is the path to progress.
It’s great to hear that you’ve already some progress in size and strength. I would personally recommend that you look a little closer at your diet. You’re carrying some extra body fat that is hiding your muscle growth.
There’s a 1000 opinions of nutrition so many people may share different perspectives. Personally, I try to stick with carbs and protein for as much of my calories required. You want around 0.75- 1 gram of protein per lbs of weight (not sure how that converts to kg). This will support adequate muscle growth. Carbs provide the fuel for your body systems and your energy. Fat is harder for your body to consume and excess dietary fat can be stored as reserves.
60lbs in 9 months is plenty of bulking. Keep up with training, clean up the diet (lean bulk), and keep things moving. You can continue to GRADUALLY add muscle and shed some of the body fat. Patience and determination is necessary.
