Is it worth it to take mk677/hgh

[caay]

As of rn im currently 5'11 and 150lbs at 14y yo's (I turn 15 in a few months) and i'm wondering if its worth it to take hgh/mk677. I know they have different effects but im wondering if its worth it to take either of them. My dads 6'3 and my moms 5'10 im also pretty sure that my grandpa was around 6'4. I smoked weed for a bit a couple months ago pretty consistently for like 5 months and I know it probably stunted my growth so im debating if i should take some sort of enchancement in order to get back what I lost.

(also need tips on how to order shi on indiamart most of my money is wrapped in apple pay and my parents can see my notifications looking for other payment and shipment methods i could use to hide purchases)
