What should i stack next?

im looking to add for cognitive health, longevity, healing and better sleep. i am currently taking tirz bi weekly. six days and one day off for semax, selank, and additional bpc 157 for knee pain to improve.

i take pt-141 once if needed hehe. and kispeptin every other day.

bpc is god send for my knees but felt a bit stiff so i need to have a complete stretch everyday. semax and selank completely remove the flat feeling of tirze. glow, i felt my skin smoother, smaller pores and lost 4kg with tirze in 7 weeks.

im changing to reta once my last dose of tirz finish in a couple of weeks.

im torn with motc, cagri, cjc no dac, pinealon, ss31 and dsip. but i heard dsip hits or misses. so yeah.
