Private lab link. Heavy Metals Profiling for Longevity screens for arsenic, mercury, lead, and other metals that can contribute to mitochondrial stress, oxidative load, vascular aging, and cellular aging pressure. Use this category when the question is whether toxicant burden may be part of the longevity risk picture. Unlock opens the already-discounted lab storefront.
Availability note: At-home testing is unavailable in New York and has limits in New Jersey and Rhode Island. Non-U.S. members can message Kat for the alternate ordering process.

Private lab link. Aging, Hormones, Gut & Inflammation Labs is a broader lab collection for biological age, NAD status, DUTCH hormones, organic acids, microbiome mapping, and inflammatory cytokines. Use this category when the question spans aging pace, hormone context, gut metabolism, or inflammation rather than one isolated marker. Unlock opens the already-discounted lab storefront.

Private lab link. The Melatonin 4-Point Saliva Test gives a day-long melatonin profile so you can see timing and production levels rather than guessing from bedtime, wake time, or supplement response alone. Use it when the question is whether melatonin rhythm, not just sleep behavior, is part of the problem. Unlock opens the already-discounted lab storefront.

Private link. The 3AM Decoder helps members sort the likely contributors behind middle-of-night wakeups and trouble falling back asleep. It maps the question from "what should I try right now?" to the daytime and overnight contributors that shape sleep re-entry capacity, including autonomic arousal, blood sugar, inflammation, hormones, circadian timing, and recovery inputs. Unlock to open the Decoder.
