THREAD: NAC on sale at Costco - too good to be true or legit deal?Started by CrystalCathy206

hey everyone! just saw NAC gummies at Costco for like half the price i usually pay online. i'm a broke student so this seems amazing, but i'm worried - does cheaper mean lower quality? or is this a total steal? anyone tried the Costco brand ones?

CrystalCathy206 - weekend warrior here. i've grabbed NAC from target when it's on sale before. sometimes it's just overstock or a promo. check the label tho - make sure it's the same dosage and no weird fillers. if it's legit NAC, go for it! my joints feel better with it after long hikes.

as a gym rat, i'm picky about supplements. costco's kirkland brand is usually solid for basics. i'd compare ingredients to your usual brand - look for purity, no artificial junk. if it's clean, snag it! i got some at my local pharmacy once and it was fine, just not my preferred flavor lol.

skeptical mom here - i always research sales! lower price doesn't always mean worse, but check expiration dates and reviews. sometimes stores discount older stock. if it's a reputable brand at costco, it's probably safe. i'd still start with a small batch to see if it works for you before stocking up.
