Scent blockers and beta boosters are two sides of the same coin. Scent blockers are usually used by omegas and/or alphas in order to mask their scent. This is common for people who do not want others to know their secondary gender.

Beta boosters are usually taken in order to become more like a beta, or "beta-passing." They can be used in tandem with scent blockers to effectively pass as a beta in society (instead of an alpha or omega).
