Cellular & aging
Epitalon
A short peptide discussed in aging and cell research. There are major gaps in evidence about use in people.
Why people are interested
Epitalon became popular in longevity and sleep discussions because cell studies found telomere-related signals and small human studies measured circadian biomarkers and a retinal condition. Those findings are much narrower than claims that it reverses aging or fixes sleep.
What the research supports
A small 2021 study gave a sublingual AEDG/Epitalon spray to night-shift workers and measured a melatonin metabolite and clock-gene expression, not sleep quality. A 2002 clinical report studied injections around the eye in retinitis pigmentosa. Neither tested a subcutaneous research vial for longevity or insomnia. Older Epithalamin extract studies concern a different substance.
Clinical or label amounts
Limited human research; different routes
0.5 mg total per day
Twice-daily sublingual spray for 20 days
Specific to the named study or medicine, not this research vial.
Tirzepatide acts on GIP and GLP-1 receptors. It has been studied in human medicine products for blood sugar and metabolic effects.
Why people are interested
Tirzepatide is well known because prescription versions are used for type 2 diabetes, chronic weight management, and certain sleep-apnea patients. JD-2TR is a seller code associated with tirzepatide in listed batch reports.
What the research supports
The strongest evidence belongs to manufactured prescription tirzepatide products studied in clinical trials. FDA approval applies to those products and specific indications, not automatically to a research-only JD-2TR vial.
Clinical or label amounts
Prescription product label
2.5–15 mg
Once weekly in adults
Specific to the named study or medicine, not this research vial.
FDA-approved uses belong to named prescription products and indications; they do not transfer to an online research vial. Human, animal, cell, and anecdotal evidence are different. How we check sources →
