Usually you'd rely on educated guesswork like this - and in many cases the character isn't pronounced exactly the same because of drift (https://en.wikipedia.org/wiki/Chinese_character_classification#Sound_change), but Chinese isn't as precise as many people make it out to be: "When one encounters such a two-part character and does not know its exact pronunciation, one may take one of the parts as the phonetic indicator. For example, reading 詣 (pinyin: yì) as zhǐ because its "side" 旨 is pronounced as such. Some of this kind of "folk reading" have become acceptable over time – listed in dictionaries as alternative pronunciations, or simply become the common reading. For example, people read the character 町 ting in 西門町 (Ximending) as if it were 丁 ding".
The advice is meant for the majority of phonetic-semantic characters, which is 80% of the language. It requires a good base, of course, so it'd be applied in middle-school level and up.
Your example is equivalent to saying you don't know how to pronounce "baa" because you know the letter "a" but not the "b". If you know 冫 then you know 冰.
That's where people order the active ingredients of hormone therapy and compound their own tinctures, creams, sprays, and injections.
12% (likely lower) of the community makes their own stuff, and the overwhelming, overwhelming majority of the 12% is just making estrogel. It's not as DIY as something like this article or the other "biohacking" stuff.
