Epitalon 50 mg: What This Bulk Vial Size Actually Means

Epitalon 50 mg refers to a single vial containing 50 milligrams of epitalon, a synthetic tetrapeptide sold as a lyophilized powder for laboratory research. Because most epitalon vials hold 5 mg or 10 mg, a 50 mg vial is a bulk size that carries roughly five to ten times the peptide of a standard research vial. Epitalon is not approved by the FDA for human use in the United States, and the information below is educational rather than medical advice.

What Epitalon Is and Why the 50 mg Size Exists

Epitalon, sometimes spelled epithalon, is a four-amino-acid peptide (alanine-glutamate-aspartate-glycine) that has been studied in cell and animal models for its effects on telomerase activity and pineal regulation. Most of that research comes from a small number of laboratories, and human clinical data remains limited.

Vendors sell research peptides in several sizes so buyers can match quantity to workload:

• 5 mg and 10 mg vials — the standard single-project sizes for individual researchers.
• 50 mg vials — a bulk option that equals five 10 mg vials or ten 5 mg vials in one container.
• 100 mg vials and above — wholesale or institutional quantities.

The practical reason to choose 50 mg over 10 mg is cost per milligram. Bulk vials usually list at a noticeably lower price per milligram, which matters when you are running repeated assays, comparing concentrations, or sharing material with a lab group.

Epitalon 50 mg Compared With Other Vial Sizes

Vial size	Total peptide	Typical buyer	Relative cost per mg
5 mg	5,000 mcg	Single small experiment	Highest
10 mg	10,000 mcg	Individual researcher	Moderate
50 mg	50,000 mcg	Multi-run or shared lab	Low
100 mg	100,000 mcg	Institutional or wholesale	Lowest

Compare listings for epitalon 10 mg and epitalon 100 mg and the pattern holds: the bigger the vial, the lower the per-milligram price and the larger the upfront cost. A 50 mg vial sits in the middle of that range.

There is a tradeoff. Once a vial is reconstituted, the peptide degrades over weeks, so buying more than you can use in a reasonable window tends to waste material rather than save money. An unopened lyophilized 50 mg vial stored properly lasts far longer than a reconstituted one.

How to Reconstitute a 50 mg Epitalon Vial

Reconstitution follows the same steps at any vial size: add bacteriostatic water, swirl gently, and let the powder dissolve. What changes with 50 mg is the concentration, because the same volume of water now holds five times more peptide than a 10 mg vial would.

1. Swab the rubber stopper with alcohol and let it dry completely.
2. Draw your chosen volume of bacteriostatic water into a syringe.
3. Inject slowly against the inner wall of the vial instead of directly onto the powder.
4. Swirl the vial gently until the solution is clear; never shake it, because agitation can damage the peptide.
5. Refrigerate after the powder is fully dissolved.

Bacteriostatic water added	Concentration	Concentration in mcg/mL	Volume containing 1 mg
2.5 mL	20 mg/mL	20,000 mcg/mL	0.05 mL
5 mL	10 mg/mL	10,000 mcg/mL	0.10 mL
10 mL	5 mg/mL	5,000 mcg/mL	0.20 mL
25 mL	2 mg/mL	2,000 mcg/mL	0.50 mL

The same arithmetic applies when people ask how much bac water for 10 mg retatrutide, and the process is identical whether you are reading a guide on how to reconstitute epitalon 10 mg or handling a larger 50 mg vial. Units cause the most errors: 1 mg equals 1,000 mcg, so a misplaced decimal changes the concentration tenfold.

Storage, Stability, and Handling

Lyophilized epitalon is more stable than the reconstituted solution. Store the sealed powder in a freezer, protect it from light, and keep it dry.

• Unopened powder: freezer at roughly -20°C, away from light and moisture.
• Reconstituted solution: refrigerate at 2–8°C and use it within a few weeks.
• Refreezing reconstituted peptide: generally avoided, since freeze-thaw cycles can degrade the peptide.
• Handling: use sterile technique and dedicated supplies for every vial.

Safety, Legal Status, and Research Limits

Epitalon is sold as a research chemical, not as an approved drug. The FDA has not approved epitalon for human use in the United States, and no regulated pharmacy dispenses it as a treatment.

Published research on epitalon is dominated by in vitro and animal work, with a small number of older human studies of limited size. Claims about anti-aging effects, lifespan extension, or disease treatment are not supported by strong clinical evidence.

Anyone considering epitalon for personal use should talk with a licensed healthcare professional first and should weigh the lack of regulatory oversight in the research-peptide market.

How to Judge a Vendor Selling Epitalon 50 mg

Because the peptide market is lightly regulated, the vendor matters as much as the product. Look for these signals before ordering:

• A third-party certificate of analysis that names the specific lot and reports purity by HPLC.
• Clear labeling of net peptide content, since some sellers list total vial weight instead of peptide weight.
• Cold-chain or insulated shipping during warm months.
• Real contact information and a published return policy.
• Consistent inventory across sizes rather than a single product page.

Many of the same sellers also carry unrelated research compounds such as aod 9604 5 mg, so reviewing quality documentation across an entire catalog is a better gauge than the marketing copy on one listing.

COMMON QUESTIONS

Frequently Asked Questions

Is epitalon 50 mg the same thing as epithalon?

Yes. Epitalon and epithalon are two spellings of the same synthetic tetrapeptide, and the 50 mg in the product name describes how much lyophilized powder is in the vial. It is not a dose, a strength rating, or a suggested amount to use.

How much bacteriostatic water should I add to a 50 mg epitalon vial?

There is no single required volume, and the right amount depends on the concentration your work calls for. Adding 5 mL produces 10 mg/mL, while 10 mL produces 5 mg/mL and 25 mL produces 2 mg/mL. More water makes small measurements easier to draw accurately; less water keeps the total vial volume small.

Can you buy epitalon 50 mg legally in the United States?

Research peptides like epitalon are sold for research use only and are not FDA-approved drugs, so they cannot legally be marketed as supplements or medicines for human use. Buyers generally do not face automatic legal trouble for possession, but products sold outside FDA oversight carry real purity and safety risks. Talk with a healthcare professional before using any research peptide.
