I'm 5 10 and 19 years old and the only supplements that i've ever taken is the trifecta stack by lg sciences (Methyl 1-d, masterdrol, and then the pct)... I took the supplements three times..once when i was 17 , once when i was 18, and then once when i was 19. I heard that prohormones closed growth plates so i'm wondering if i stunted my growth permanently from taking these supplements three times for a month at a time?? Thanks for the help guys
