Epitalon Subcutaneous Research Dosing Protocol
-
For research use only. Not medical advice.
Overview
Epitalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide studied for its potential effects on telomerase activation, cellular longevity, circadian rhythm normalization, and antioxidant regulation.
Research use typically involves short, intensive cycles rather than continuous long-term dosing.Daily Dosing Protocol (Subcutaneous)
Standard Daily Range
10-20 mg once daily
The 10 mg daily dose is the most commonly cited range in aging and telomere-focused research.
Cycle Length Options
- Standard Cycle (Most Common)
10 days
Daily dose: 10–20 mg
Researchers commonly run Epitalon as a short burst cycle, then take an extended break.
- Extended Cycle (Alternative Model)
20 consecutive days
Daily dose: 10–20 mg
Used in some longevity-focused research models aiming for prolonged telomerase expression and circadian modulation.
Timing
Once daily, any time of day
Some researchers prefer evening dosing given its historical use for circadian rhythm correction, but timing is flexible.
Frequency & Cycling Pattern
Typical long-term patterns:
Annual or Semiannual Cycles
10–20 days on,
Several months off
In aging-related research, Epitalon is rarely used continuously — it is almost always delivered in short, high-intensity cycles, sometimes 1–4 times per year depending on the model.
Common Research Notes
Effects are subtle and accumulate gradually — often evaluated by sleep quality, recovery, or long-term biomarkers.
Some subjects report improvements in sleep consistency, recovery, and perceived vitality.
Because cycles are short, tolerability is usually excellent.
Epitalon is often paired with circadian-focused interventions or other mitochondrial peptides for synergistic longevity research.

I have seen it alleged in several places (sadly without adequate sourcing) that the 10-20mg dosing was for Epithalamin (the pineal gland extract) not Epitalon (the synthetic peptide derived from what was found in Epithalamin) and thus the dosage for Epitalon should be much smaller.
Does anyone have references or data to help disambiguate here? Or am I mistakenly repeating unfounded rumors?
-
There is real confusion in the literature, largely because Epithalamin (pineal extract) and Epithalon/Epitalon (the synthetic AEDG tetrapeptide) are frequently conflated.
The claim that all 10–20 mg dosing applies only to Epithalamin is not clearly supported. Reviews of the Epithalon (AEDG) human literature show multi-mg “course” dosing does appear for the synthetic peptide as well, depending on route (intranasal or IM), while much lower doses (sub-mg) have also been reported in specific circadian focused studies.
The real issue isn’t that high doses are “wrong,” it’s that route, formulation, and study context matter, and many secondary sources fail to specify which protocol they’re referencing. There is no single, universally accepted human dosing standard for Epithalon alone.
-
There is really nothing conclusive on Epitalon dosing and protocols. It is one of those leap-of-faith compounds that you take and it may or may not be doing something. The correct dosing protocol, if one even exists, is anyone's guess, and it is hard to assess efficacy because this peptide does not produce any immediate, noticeable effects.

@jeremy2026 Hard to measure I totally buy. WRT * noticeable* I have experienced what feels like significant improvements in my sleep. A lot of that might be placebo. But some of it is objective - I wake up fewer times per night.
-
I am planning to research epitalon soonish. Was wondering if there would be any benefit to a 5mgx10 day cycle or if 10x10 is the absolute minimum. I have read where testing was done on a 5x20 cycle. I was thinking dip my toes and see if it helps.
I am also curious about reconstitution. I have 5 10mg vials and don’t particularly want to inject 100 units per shot. Is there a safe, reasonable, minimum reconstitution volume that will dissolve the peptide and not result in any issues? Say 1ml/10mg and do 50 units? Lower? Just thinking about it from the perspective of taking it daily or multiple times a day.
-
Thanks for the feedback. Yeah, I have read that 5mg is typically the minimum dose amount. I should probably just buy 5 more vials and do a 5x20. Been stocking up, so I’m spread a bit thin atm.
-
@researchcat I can report that 2mg per day has been dramatically noticeable for me (in a very positive way) in terms of improved sleep. That said the only downside I've ever heard anyone report about the higher dosages is that it made them a little drowsy during the following day.

I agree… First round/cycle i did 5mg for 20days. Next cycle i will up the dose and check DNA telemeres to see what happens as well

Telomere check is also my research plan
Already have established telomere baseline, so longer on next test (in approx 6 months) = the Epitalon worked.To add another data point, I happened to do 10mg daily for 20 days. As noted, no one knows. I felt fine and feel fine.

we just parterned with a testing company thats dirt cheap https://peptidecritic.com/lab-tests/ulta-bloodwork
Im on the road so i have to check what theyre calling the telomere length test but you absolutely should do it before and after on your rat.

@Randy I checked Ulta and the other lab providers and couldn’t find it. I did see some companies that do just this testing for 250-300. FlowFish, PSC, Spectra, a couple others.
I have a similar reconstitution question to what I asked in the SS-31 thread: for reconstituting 10mg vials where you are injecting basically the entire vial, is only using .200 ml or a little more ok rather than using 1ml+? I am just not sure if you would get the peptide to dissolve completely and/or there would be irritation or absorption issues due to the concentration.
Thanks.

Just got my TruDiagnostic Advanced TruAge report results yesterday, includes telomeres. This is one month after Epithalon course, so better results to come in later this year, in theory:

@ResearchCat yeah the whole thing. .5ml because its a stingy one
