Because bromelain is a proteolytic (protein-digesting) enzyme, taking it with a steak or heavy protein shake will cause the enzyme to expend its energy digesting the food rather than chaperoning the flavonoids into the bloodstream or acting as a systemic anti-inflammatory

Similarly, it has been shown that the activity of 20S proteasomes is not restricted to the complete degradation of its substrate, but rather there are proteins that are cleaved by the 20S proteasome at specific sites to generate functional cleavage products (Baugh and Pilipenko, 2004
A study in the Journal of Controlled Release confirmed that microneedling enhances peptide penetration through the stratum corneum by up to 10-fold (PMC3016279)
Observed side effects in research environments are generally mild and temporary, most commonly including: Temporary fatigue-related observations Mild fluid-retention variability Increased hunger- or appetite-related observations Mild headache-related observations Minor administration-site irritation such as redness or temporary administration-site sensitivity observations Proper reconstitution, sterile handling practices, proper administration techniques, and regular administration-site rotation are important for minimizing local irritation and maintaining peptide stability and consistency during research use
