Not too sure as far as supps go. However, my wife who has the worst allergies to my knowledge can take Thymosin alpha 1 in the morning and its typically cleared out by that evening. She takes one shot of 750mcg. Typically will keep her good to go for the next week or so
I swear by it man. Give it a try with one vial and watch how well your body attacks the sinusesGood call on that, it’s brutal man. Feel like I got hit by a bus combined with congestion
