Who makes Kirkland Signature Energy Shot, 2 fl oz, 48-count?

Searches of product_description for 'energy shot' + 'kirkland' returned no Kirkland energy-shot recall; the matches were unrelated products (a '4HB Stack' bedtime supplement, an Amrita energy bar, an Inked Mango energy drink). No co-packer surfaced via the recall route.

Energy shots are FDA-regulated dietary supplements, outside CPSC jurisdiction; the handful of 'Kirkland' CPSC recalls on file are unrelated non-beverage items. No maker identified.

The Kirkland energy shot is marketed as a dietary supplement, which carries no NDC labeler code and no ANDA sponsor, so the NDC-to-ANDA join that resolves Kirkland OTC drugs dead-ends here. No maker identified.

The only opinion surfaced by 'kirkland' + 'energy shot' is Innovation Ventures, LLC v. Custom Nutrition Laboratories, LLC (E.D. Mich. 2017, 256 F. Supp. 3d 696). The 'Kirkland' token is the law firm Kirkland & Ellis (counsel), not the product; the case concerns a non-compete covenant over 5-Hour Energy's formula and never names Costco/Kirkland or identifies who makes the Kirkland energy shot. No litigation names a co-packer.

Costco's manufacturer field appears only on the new-format (/p/-/) product pages, which are not captured in the Wayback Machine for this item; the archived legacy product pages (2017-2024) carry no manufacturer field. Costco discloses no maker.

Every accessible listing shows 'Distributed by Costco Wholesale' only; none names a manufacturer or co-packer. Open Food Facts lists Kirkland/Costco with no producer field.

Coverage (e.g. Daily Meal) frames the Kirkland shot as a cheaper alternative to 5-Hour Energy but names no maker. ImportYeti is bot-blocked and structurally weak for a domestically produced supplement. No maker identified.
