After getting those 15 kg dumbbells, and about few weeks of lifting, I had an injury of hand where apparently my hand bones arent strong enough to do biceps curls with 15 KG. the injury forced me to stop working out for some time.
While my muscles can handle that weight, my wrists and my hand bones seem to struggle. I also had problem with doing push ups due to weak wrists which cant handle pressure well. It took me some time to reach 20 push ups and gradually strengthening wrists.
Anyway, I was thinking between getting creatine or protein powder, and there seems to be a clear winner.
Creatine is much cheaper. 500 grams of creatine can last up to 100 days, where 5 kg of protein can last 100 days, but 5 kg of protein is much more expensive than 500 grams of creatine.
When it comes to price, winner was obvious. I only need 5 grams of creatine per day, so 500 grams of creatine last over 100 days probably, and the price of creatine 500 grams is about 25$.
Also, creatine benefits the brain as well much more than protein does, which is one of reasons I chose to get it.
I actually ordered mass gainer before, but delivery got cancelled, apparently seller out of supplies. But mass gainer is basically mosty sugar, and I can simply buy sugar itself instead of buying mass gainer.
But creatine is definitely special. While I can get protein from eggs, creatine seems to be much more valuable resource, as valuable as sugar, and it is more difficult to get it from food when you are a vegetarian.
So yeah, right now I can do 45 repetitions with 10 kg dumbbell. I will see if, after creatine, that number significantly increases (creatine is supposed to give about 20% boost).
