I use both Boveda and Integra Boost, never once noticed any issues with them "stealing terps."
Food for thought on the topic; the only actual "study" that I know of ever produced that even suggested Boveda packets actually cause terpene loss was produced by someone that worked for Desiccare, who makes.... Integra Boost, literally the only main competitor to Boveda. Those two companies also had an on-going lawsuit (not sure if it's still going.) Little suspicious IMO lol...
