It definitely is but since I ran out I had to settle on what the pharmacy had and that was 22g1. I was lucky to have even found that since most other pharmacies didn't even have intramuscular needles in stock. My main concern was that I didn't take in enough sust but I'm just OCD at times, especially when it comes to things like this haha I notice the slightest decrease in strength and I immediately think that I'm not getting enough sust haha![]()
