Please Note — Expired UK Stock This stock is expired. We're telling you this upfront rather than burying it: it's still usable, past peak potency, which is why it's priced lower than a fresh-stock equivalent. Power Si availability has been affected across the whole UK market recently, so this is the same batch situation most UK sellers are currently working with — if you see it listed elsewhere at full price with no mention of this, it's worth asking whether they're selling the same expired stock without telling you.
