Epithalon Dosage: How Pepti Prescribes It, in Units, mL and mg

Every price is all-in, covering medication, physician review, refill management and shipping, with no separate membership fee. Pepti is cash-pay and does not bill insurance. Epithalon is a vial drawn with an insulin syringe; there is no Pen version. These are the typical printed directions; your own directions are the ones on your vial.

Pepti's directions are written in two forms, millilitres and units, because prescriptions are written in millilitres and insulin syringes are marked in units. On a U-100 insulin syringe, 1 unit is 0.01 mL, so 100 units is 1 mL and 25 units is 0.25 mL. A unit is a volume mark on the barrel, not a measure of how strong the medication is.

The milligram figure comes from the concentration on the label. Pepti's epithalon is supplied at 2 mg/mL, so:

That arithmetic is a way to read a label, not a way to set a dose. A vial labelled 10 mg is not a 10 mg dose: it is twenty 0.5 mg doses. Online epithalon protocols often quote doses for powder vials that the reader mixes at home, at a concentration that depends on how much water was added; a Pepti vial arrives already in solution at a fixed concentration, so those figures do not transfer; do peptides come pre-mixed explains the difference. If your label and your syringe seem to disagree, do not dose; message your care team. How long does a peptide vial last explains every number on a vial label.

The chart below is the conversion for a 2 mg/mL vial, drawn with a U-100 insulin syringe. It is math only. It is not a menu of doses, and the only line that applies to you is the one that matches the number printed on your vial.

The rule behind every row: units divided by 100 gives millilitres, and millilitres multiplied by 2 gives milligrams.

Epithalon in the ETERNAL blend

The ETERNAL Blend holds epithalon at the same 2 mg/mL, so the same 25 unit draw delivers the same 0.5 mg of epithalon. It also delivers the other three ingredients in fixed proportion:

There is no way to take more epithalon and less of something else from the same vial; a different balance is a different prescription. More on the blend is in what is the ETERNAL blend.

At Pepti's typical directions, one 10 mg vial lasts four weeks:

Four weeks is why refills run every 28 days, one vial per fill. Vials are multi-dose solutions shipped ready to use, refrigerated with ice packs, with sterile syringes and alcohol prep pads. Nothing is mixed at home. Keep the vial in the fridge between doses. The FDA's July 2026 briefing noted that reconstituted epithalon is stable for only days at fridge temperature in the manufacturer's data, so the beyond-use date the pharmacy prints on the label governs; it runs from first puncture. How to store peptides covers storage.

If a vial runs short before the refill, message your care team rather than adjusting anything yourself. If you miss a dose, follow your directions and do not take two doses to make up for one.

The protocols from the St Petersburg institute that developed epithalon were intermittent: courses separated by months. The anchor mouse study, Anisimov and colleagues in Biogerontology in 2003, gave epithalon in brief monthly courses, not continuously. Prescribers generally follow that logic rather than treating epithalon as an indefinite daily medication.

There is also a safety reason. The FDA's July 2026 review raised a concern that continuous, long-term telomerase activation could in principle allow cells to escape senescence, and the rodent work that found fewer tumours used intermittent courses totalling a few months of exposure. How long a course runs, and whether and when it is repeated, is set by your physician after reviewing your intake; do not improvise a permanent schedule. Peptide cycling and tolerance covers how courses work across peptides.

People search for "the" epithalon dose expecting a trial figure. There is not one to give:

When the FDA reviewed epithalon in July 2026, it found no human pharmacokinetic data and no study of the subcutaneous route at all. The honest reading is that the injectable dose in common use comes from clinical convention, not a dose-ranging trial. That is why your directions come from a physician who has reviewed your intake. The evidence, one claimed benefit at a time, is in epithalon benefits.

Your physician sets your directions after reviewing your intake. Things that can lead to different directions, or a different product, include:

When directions change, the new numbers are printed on the new label. Never carry a number over from a previous fill. Bloodwork is not required for any Pepti treatment. If your physician wants labs for your care, they'll ask through your account.

The full picture is in what is epithalon.

What is missing matters more than what is reported. The FDA's 2026 review found no clinical safety study, no formal toxicology and no adverse-event reports, which is an absence of data rather than evidence of safety. Anyone with a personal or strong family history of cancer should raise it on the intake, because telomerase activation is the mechanism by which cells escape senescence; see can peptides cause cancer. Epithalon is not used in pregnancy or breastfeeding. It is not named on the 2026 WADA Prohibited List, but the S0 class covers substances without approval for human use, and the ETERNAL Blend contains TB-500 and BPC-157, which are named; tested athletes should check before starting.

Epithalon was removed from Category 2 of the FDA's 503A list on 15 April 2026, and on 24 July 2026 the FDA's Pharmacy Compounding Advisory Committee voted 7 to 4, with one abstention, to recommend adding it to the 503A Bulks List; the FDA's final determination is pending. Compounded medications are not FDA approved.

Epithalon cannot be bought legitimately without a prescription. Sites selling it "for research use only" are not accountable for what is in the vial: identity, purity, sterility and concentration are untested, so the concentration a units chart depends on is unknown. The prescription route:

1. Complete a free online intake covering your history, medications and what you want help with.
2. A physician licensed in your state reviews it, usually within 24 hours.
3. If it is appropriate, a PCAB-accredited, FDA-registered US 503A compounding pharmacy prepares it to that prescription. Lot test results are published at /quality/lab-results.
4. It ships refrigerated with your directions printed on the vial.
5. Your physician stays reachable for questions and dose changes.
