Epithalon quick reference: mg ↔ units

Bidirectional reference for a 10 mg Epithalon vial reconstituted with 2 mL BAC water (concentration 5.00 mg/mL).

Dose (mg)	Dose (mcg)	U-100 units
2.5	2500	50
5	5000	100
10	10000	200
20	20000	400

Read across in either direction. The mg ↔ units relationship is linear at a fixed concentration — change vial size or BAC water and every row in this table moves.

Worked example

Epithalon mg ↔ units, both directions on one vial

Working from one 10 mg Epithalon vial mixed with 2 mL of bacteriostatic water → 5.00 mg/mL.
mg → units: 5 mg ÷ 5.00 × 100 = 100 units.
units → mg: 100 units ÷ 100 × 5.00 = 5 mg — round-trip exact, that's how you sanity-check a logged value.
mcg flip: 5 mg = 5000 mcg, useful when the protocol writes the dose below the 1 mg threshold.
Every row here is specific to this vial; reconstitute with a different volume and you start from a different concentration.

Scenarios people actually run into

Three things that come up logging Epithalon

Protocol says 5 mg. Syringe says 100 units. Those are the same draw on this vial — and only on this vial.
Someone online says "Epithalon dose is 20 units." That number is meaningless without their vial mg and their diluent mL. Ignore the units number and convert from the mg.
Logged a dose in units last week and a dose in mg today. The mg ↔ units flip on this page is how you confirm both entries describe the same actual draw.

Epithalon is a short four-amino-acid peptide people use in cycles, usually for sleep quality and as a longevity-adjacent experiment. The interest comes from research suggesting it can lengthen telomeres — the protective caps on the ends of chromosomes — and influence the pineal gland's melatonin rhythm. The original Russian trials reported telomere-length increases and improved sleep markers, but independent replication is limited. This page covers reconstitution math and how people log a typical 10–20 day cycle.

How the Epithalon mg ↔ units converter works

Epithalon doses are written in mg (5, 10), much larger than typical peptide doses. This converter handles the mg-to-units math at your vial concentration so the larger draws land precisely.

The formula in both directions: mg = mL × concentration mg/mL, and units = mL × 100 on a U-100 syringe. With a 5 mg/mL Epithalon solution, 5 mg comes out to 100 units, and 100 units comes out to 5 mg. The converter handles the unit flip automatically so you never multiply or divide in your head while holding a syringe.

Concentration is the input that changes the answer most. A 10 mg vial diluted with 1 mL is twice as concentrated as the same vial diluted with 2 mL, which means the same dose draws half as many units. That is the single biggest source of converter confusion: a remembered unit count from an old vial does not transfer to a new vial reconstituted with different water volume.

Tracking Epithalon unit counts

For Epithalon, the most informative data points to log for longitudinal review are the cycle start and end dates. Because research protocols are structured around short, discrete administration periods followed by long planned breaks, a simple list of daily doses is less meaningful than a clear record of these cycles. Documenting the specific date ranges of each 10-to-20-day course makes it possible to analyze the protocol's timing, frequency, and duration on a year-over-year basis. This high-level view is essential for anyone aiming to observe patterns consistent with the published literature.

Common Epithalon mg ↔ units mistakes

Reconstituting a 10 mg vial with 2 mL of diluent and not anticipating that a 5 mg dose requires drawing the full 100-unit capacity of a 1 mL syringe.

Frequently asked questions about Epithalon mg ↔ units

What's the formula behind this Epithalon mg ↔ units converter?

Both directions use the same concentration. Going mg → units: (dose mg ÷ concentration mg/mL) × 100. Going units → mg: (units ÷ 100) × concentration. For this Epithalon example at 5.00 mg/mL, 5 mg works out to about 100 units, and the same number of units converts back to 5 mg. Epithalon mg-scale doses are unusual in the peptide world — most protocols specify mg directly without unit translation.

Why does my Epithalon unit count not match a number I read online?

Almost always because the other source assumed a different vial concentration. A "Epithalon dose = 20 units" tip is meaningless without knowing whether the vial was reconstituted with 1, 2, or 3 mL of water. The converter on this page asks for your actual vial mg and diluent mL so the answer reflects your vial, not someone else's. Epithalon mg-scale doses are unusual in the peptide world — most protocols specify mg directly without unit translation.

Does the Epithalon converter handle mcg as well as mg?

Yes — 1 mg equals 1,000 mcg, and the converter does the unit flip automatically when you switch the input. This matters for peptides where typical doses sit below 1 mg: a 250 mcg Epithalon dose displayed as 0.25 mg is the same number, just easier to read. Epithalon mg-scale doses are unusual in the peptide world — most protocols specify mg directly without unit translation.

When would I convert Epithalon units back to mg?

Most often when checking a dose someone else recorded. Logs and protocols sometimes write the dose in units (because it's what shows on the syringe), other times in mg (because it's what the protocol step is named). The reverse direction lets you confirm a logged unit count actually matches the planned mg target before drawing the next dose. Epithalon mg-scale doses are unusual in the peptide world — most protocols specify mg directly without unit translation.
