Superthrive B-Vitamins and Hormones

For visibility sake I started a thread to expand on @jeremybyington question
Expired Vitamin B Complex in the garden? - General Gardening - Growing Fruit

@Drew51 has mentioned Superthrive before its has “50” vitamins and hormones but its primarily Vitamin B1 and NAA ( 1-Naphthaleneacetic acid). NAA is readily available and is used to prevent fruit drop, increase cellulose formation and improve the uptake of other nutrients in solution.

Please share experiences with superthrive and other “concoctions”
