Epitalon 100 mg: Vial Size, Reconstitution, and Storage

Epitalon 100 mg is a single vial containing 100 milligrams of epitalon, also spelled epithalon, a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It is a bulk research quantity rather than a dose, since most laboratory protocols describe microgram to low-milligram amounts. Epitalon is not FDA-approved for human use in the United States, and nothing about a larger vial changes that.

What the 100 mg Label Actually Means

Lyophilized peptide vials list the total mass of peptide inside the vial, not a serving size and not a recommended amount. A 100 mg vial is a bulk format that holds roughly ten times the peptide of a common 10 mg vial.

• Net peptide vs. total mass: some vendors report total powder weight, which can include salts or bulking agents. A certificate of analysis should show net peptide content plus purity by HPLC.
• Purity: research-grade epitalon is typically listed at 98% or higher, verified by HPLC and mass spectrometry.
• Form: shipped as a lyophilized (freeze-dried) cake or powder that must be reconstituted before any laboratory use.

The bigger quantity mainly changes handling, storage, and cost per milligram. It does not change the peptide's identity or its regulatory status.

Epitalon 100 mg vs. Smaller Vial Sizes

Vial size is a practical choice. Smaller vials are easier to reconstitute and use up before degradation, while larger vials lower the cost per milligram and reduce the number of separate orders.

Vial size	Total peptide	Approx. 100 mcg aliquots	Typical handling note
5 mg	5,000 mcg	50	Smallest common format; easy to keep sterile
10 mg	10,000 mcg	100	Widely stocked; simple 1-2 mL reconstitution
50 mg	50,000 mcg	500	Mid-bulk; usually split into aliquots
100 mg	100,000 mcg	1,000	Bulk; needs larger diluent volumes or splitting

Many researchers keep epitalon 10 mg vials as working stock and reserve 100 mg vials for long studies or for splitting into smaller sealed portions. Other peptides sold by weight, such as aod 9604 5 mg, follow the same logic: the number on the label is a quantity, not a suggested amount.

Reconstituting a 100 mg Vial: The Math

Reconstitution is simple arithmetic. Concentration equals total peptide mass divided by the volume of diluent added. Bacteriostatic water is the usual choice because its preservative slows microbial growth in a multi-use vial.

Bacteriostatic water added	Concentration	Volume for 100 mcg	U-100 syringe units
5 mL	20 mg/mL	0.005 mL	0.5 units
10 mL	10 mg/mL	0.01 mL	1 unit
20 mL	5 mg/mL	0.02 mL	2 units
50 mL	2 mg/mL	0.05 mL	5 units

At the 10 mL mark, a 100 mg vial gives a clean 10 mg/mL solution, and a 100 mcg aliquot measures 1 unit on a U-100 insulin syringe. That target is convenient, but it also means adding 10 mL of diluent, which is more liquid than many small vials comfortably hold.

1. Swab the stopper and the diluent septum with alcohol and let both dry.
2. Inject the bacteriostatic water slowly against the glass wall instead of directly onto the powder.
3. Swirl gently until dissolved. Do not shake, because foaming and shear can damage the peptide.
4. Label the vial with the concentration and date, then store it cold and dark.

If you already know how to reconstitute epitalon 10 mg, the 100 mg process is identical and only the diluent volume changes. Because bulk vials need so much water, many researchers split the powder into several smaller vials or pre-draw single-use aliquots and freeze them instead of keeping one large reconstituted vial.

Storage, Stability, and Shelf Life

• Lyophilized powder: store at -20 °C or at least refrigerated, kept dry and protected from light. Sealed powder is commonly stable for months to years.
• Reconstituted solution: refrigerate at 2-8 °C and use within a few weeks. Bacteriostatic water extends usable life but does not guarantee stability.
• Avoid freeze-thaw cycles: repeated thawing degrades peptides faster than steady cold storage.
• Inspect before use: discard any solution that is cloudy, discolored, or contains particles.

A 100 mg vial that is fully reconstituted at once creates a large volume that must be used or aliquoted quickly. Splitting bulk powder into smaller sealed portions usually gives better long-term stability than one oversized multi-use vial.

Epitalon, Epithalon, and Pinealon: What Is the Difference?

Naming confusion is common because these peptides were first described in Russian research. The short answer: epitalon and epithalon are the same molecule, while pinealon is a different peptide with a different sequence.

Name	Sequence	Primary research area
Epitalon (epithalon)	Ala-Glu-Asp-Gly (tetrapeptide)	Telomerase activity, pineal regulation, aging models
Epithalamin	Bovine pineal extract	The original preparation epitalon was modeled on
Pinealon	Glu-Asp-Arg (tripeptide)	Neuronal and neuroprotective research

A search for epitalon vs epithalon is really a spelling question, while a search for epitalon vs pinealon compares two distinct compounds. A 100 mg vial labeled epitalon is not interchangeable with pinealon.

Safety and Legal Status in the United States

Epitalon is not FDA-approved for human use, and it is generally sold as a research chemical for laboratory study only. That labeling matters because it means there is no FDA-reviewed dose, no approved indication, and no pharmacy-grade quality guarantee.

• No standard human dose exists. Published studies use specific protocols that are not a template for self-administration, and a 100 mg vial is not a recommended amount.
• Telomerase activity is a theoretical concern. Lengthening telomeres in laboratory models raises unanswered questions about how the same mechanism might behave in abnormal cells.
• Injection risks are real: contamination, dosing errors, and injection-site reactions all become more likely when handling large, self-mixed vials.
• Quality varies between vendors. Independent certificates of analysis are the most practical way to verify purity and identity.

Anyone considering epitalon for anything beyond bench research should talk with a licensed healthcare professional first. No peptide sold as a research chemical should be treated as a proven anti-aging treatment.

Key Takeaways

• The 100 mg figure is total peptide mass in the vial, not a dose.
• A 100 mg vial holds about ten times the peptide of a 10 mg vial and roughly 1,000 aliquots of 100 mcg.
• Reconstituting 100 mg at 10 mg/mL requires 10 mL of bacteriostatic water.
• Epitalon and epithalon are the same peptide; pinealon is a different compound.
• Epitalon is not FDA-approved for human use in the United States.

COMMON QUESTIONS

Frequently Asked Questions

Is epitalon 100 mg the same thing as epithalon?

Yes. Epitalon and epithalon are two spellings of the same synthetic tetrapeptide, Ala-Glu-Asp-Gly. The 100 mg on the label describes only how much peptide is in the vial, not a different compound or a dose. Purity, net peptide content, and a third-party certificate of analysis matter far more than the spelling on the label.

How much bacteriostatic water do I need to reconstitute a 100 mg epitalon vial?

It depends on the concentration you want. Adding 10 mL of bacteriostatic water gives 10 mg/mL, while 20 mL gives 5 mg/mL and 50 mL gives 2 mg/mL. Because 100 mg is a large mass, many researchers split the powder into smaller aliquots rather than reconstituting the entire vial at once.

Is epitalon 100 mg legal to buy in the United States?

Epitalon is not FDA-approved for human use, and it is generally sold as a research chemical intended for laboratory study only. Buying or importing it for human use falls outside that labeling and may violate federal or state rules. Talk with a licensed healthcare professional before considering any human use.
