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

The 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. ETERNAL is a vial drawn with an insulin syringe; there is no Pen version. Your own directions are the ones printed on your vial.

Pepti's directions are written in 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.

ETERNAL is four peptides dissolved together in one vial, so one draw carries all four. The milligrams per dose come from each component's concentration multiplied by 0.25 mL:

That arithmetic is a way to read a label, not a way to set a dose. A vial labelled 80 mg in total is not an 80 mg dose: it is twenty doses of 4 mg combined. 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.

Fixed proportions

The four peptides are in a ratio fixed by the pharmacy's formulation. Every dose delivers the same split, and there is no way to take more of one and less of another from the same vial. GHK-Cu is 50 of the 80 mg, five-eighths of the vial by mass, so ETERNAL is mostly a GHK-Cu preparation with three smaller components alongside it. If a different balance is wanted, the components are prescribed separately.

The chart below is the conversion for the ETERNAL 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; multiply millilitres by 10 for GHK-Cu and by 2 for each of the other three. Those multipliers only hold for this vial. A chart written for a different blend or a different concentration gives different milligram figures for the same units, which is the main reason not to dose from a chart, including this one.

People often compare an ETERNAL dose with GLOW, KLOW or epithalon on its own. The draw is 25 units in each, and what that draw delivers is:

What the numbers show

ETERNAL delivers exactly the same GHK-Cu, BPC-157 and TB-500 per dose as GLOW and KLOW, and exactly the same epithalon per dose as the single epithalon vial, because all of them sit at the same concentrations. Adding epithalon to the blend does not dilute the other three. So the choice between them is about which components you need, not about strength. There is no reason to take ETERNAL alongside any of the other three: each combination would double one or more components, and every GHK-Cu blend carries a full copper dose. The epithalon dose detail is in epithalon dosage, and GLOW's in GLOW dosage.

Once daily, Monday through Friday

Pepti's ETERNAL directions say once daily Monday through Friday, with weekends off. Weekends off are part of the schedule, not missed doses. Twenty doses at five a week is four weeks, which is why refills run on a 28-day cycle. The standard label does not set a time of day; follow any timing printed on yours. The epithalon research involved evening hormone levels, so time of day is a reasonable thing to ask your care team about.

Under the skin, and where

Subcutaneous means into the fat layer, not the muscle. Abdomen and thigh are the usual sites, rotated so the same spot is not used repeatedly. Some prescribers direct injection near an affected area; others do not, because the mechanisms described are systemic. Your directions will say. Technique is covered in how to inject peptides safely.

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. A blue tint is expected in a GHK-Cu blend, because of the copper; why is GHK-Cu blue explains what a normal vial looks like. Cloudiness, particles or a colour change from what you received is a reason to message rather than inject. Keep it in the fridge and follow the beyond-use date on the label, which runs from first puncture; a multi-peptide vial is not something to keep past it. 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 epithalon component comes from research in which protocols were intermittent: courses separated by months, including the 2003 mouse study, which used brief monthly courses. The FDA's July 2026 review raised a concern that continuous, long-term telomerase activation could in principle allow cells to escape senescence. How long a course of ETERNAL runs, and whether and when it is repeated, is set by your physician after reviewing your intake. Peptide cycling and tolerance covers how courses work across peptides.

ETERNAL has never been studied as a blend, in people or in animals, so there is no trial dose for it. The evidence is per component, and none of it is a human dose study of the injectable form. GHK-Cu's human data is mostly topical creams; BPC-157's only randomised human study was a two-week enema trial reported as a 2005 conference abstract; TB-500 has no human trials; and the FDA found no human pharmacokinetic data and no study of the subcutaneous route for epithalon. The directions on the vial are a prescribing standard set to deliver one vial in four weeks. The benefit-by-benefit evidence is in ETERNAL blend benefits.

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.

Tested athletes should know that BPC-157 and TB-500 are named on the WADA Prohibited List at all times. The full reference is ETERNAL blend side effects. ETERNAL is a compounded prescription; compounded medications are not FDA approved.

ETERNAL cannot be bought legitimately without a prescription. Sites selling it "for research use only" are not accountable for what is in the vial, so the per-dose figures above would not hold. 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.
