Epithalon protocol variations — 10 days on / months off vs the longer runs

Canonical epithalon protocol is 10 consecutive days of 5–10mg sub-q, 1-2x per year. This traces back to the Khavinson work out of St. Petersburg. But I see variations now:

  • 10mg daily for 20 days
  • 5mg every other day for 30 days
  • 2.5mg daily continuous for months
  • 'Pulsed' — 5 days on, 5 days off, repeated 4 times

Is there any rational basis for the variations or are people just freelancing? The original protocol has a rationale (matching the observed telomerase induction window from the rodent work). Extending it longer with no dosing evidence is just hoping.

My plan is the canonical 10 days @ 10mg, once this year, with telomere length testing before and 6 months after. Anyone run similar and have actual data?

I did the canonical 10-day protocol with TeloYears testing pre and 6 months post. My 'telomere age' dropped 3 years which is within the test's noise band. I can't claim the protocol worked, I can claim it didn't obviously fail. The test itself is the bigger confound.

The longer protocols are freelancing. The Khavinson work specifically identified the pulse-and-pause cycle as part of the mechanism — telomerase doesn't want to be on continuously. Extending past 20 days might actively reduce the effect.

Running annual 10-day pulses for 3 years now. No measured telomere data but subjective sleep and recovery have been good. Not attributing either to epithalon specifically.

@humanin_hope good point — that kills my one-shot data plan. Might skip the testing.

Telomere length testing (FlowFISH, qPCR variants) has large intra-individual variability. Without repeat draws a single before/after comparison is nearly useless. You need 3 baseline draws over a year to even establish your noise floor.

Epithalon is one of the compounds where 'it's very safe, probably doesn't do much in humans at our doses' is the honest answer. The rodent work is elegant. The human extrapolation is a leap.

@stack_nerd half-life is short (~2-3 hours) so split dosing gives you more consistent tissue exposure. If it matters at all, AM/PM is better than one dose. If it doesn't matter, neither matters.

Dosing route question — some people do 5mg AM and PM split vs one big dose. Any reason to prefer one?

If you're going to run an anti-aging peptide with the evidence level of epithalon, run the canonical protocol. Don't improvise — it makes your n=1 uninterpretable even to yourself.
