What percentage of aluminum chloride should I look for if I sweat heavily?

For excessive sweating, reviewers in hyperhidrosis communities consistently recommend roll-on products in the 15% aluminum chloride range (Certain Dri's labeled concentration). Drugstore "clinical strength" sticks like Secret Clinical and Degree Clinical use lower-concentration aluminum salts (typically aluminum zirconium compounds) that are gentler day-to-day but rated less effective for true hyperhidrosis by specialist-subreddit consensus.
