Research shows clear benefits: Better stability than oral delivery, which exposes peptides to harsh stomach conditions Less breakdown by enzymes that would destroy the peptide before it reaches the blood Easier compliance no needles, no mixing, just spray Potential for targeted delivery to specific tissues, including the brain via the olfactory pathway Nasal delivery works very well for peptides like BPC-157 that target the whole body
Because both peptides mimic naturally occurring processes in the body, systemic side effects are rare
If NSAID use is essential between 20 and 30 weeks, it should be limited to the lowest dose for the shortest time, with consideration for ultrasound monitoring if treatment extends beyond 48 hours
Its so easy to brush off that persistent brain fog, crippling fatigue, or those weird pins-and-needles sensations as just stress or getting older
In general, high-dose B12 supplementation is safe
