Empty sterile glass vials with rubber stoppers and aluminum crimp seals — used for backups, splits, or transferring lyophilized powder. Most home peptide users don't need empty vials (you reconstitute in the original lyophilized vial). But if you do, here's what to buy.
Do you actually need empty vials?
Most home users don't. The standard workflow:
- Receive lyophilized peptide in a stoppered glass vial.
- Add BAC water to the original vial through the stopper.
- Draw doses through the same stopper for ~28 days.
- Discard when empty.
Empty vials are useful only in narrower cases:
- Splitting a large compounded vial across smaller vials (rare; not generally recommended — each transfer adds contamination risk).
- Custom reconstitution research with pre-measured BAC volumes ready to go.
- Storage of personal mixes for protocols with multiple peptides.
- Lab practice — dry-run reconstitution before using a real peptide vial.
If your use case isn't on this list, you probably need BAC water + syringes instead, plus a hard-shell VialCase.
What to look for
- Material: Type I borosilicate glass. Standard for pharmaceutical use. Resistant to chemical attack and temperature shock.
- Sterile + sealed. Look for "gamma irradiated" or "EO sterilized" in the listing.
- Rubber stopper compatibility. 13 mm or 20 mm necks. Stoppers + crimps must match the neck size.
- Amber glass (optional). UV-blocking. Useful for long-term storage of light-sensitive peptides like BPC-157, MT-2, Sermorelin.
Where to buy (Prime-eligible)
10 mL sterile vials with stoppers + crimps
Most common size. Comes with rubber stoppers and aluminum crimp seals. 10-pack typical. Use a hand crimper to seal after filling.
3 mL sterile glass vials
Compact size for single-compound reconstitutions. Easier to fit in standard fridge organizers and travel cases.
Amber glass vials (UV-blocking)
Tinted glass for long-term storage of photosensitive peptides like BPC-157, MT-2, and Sermorelin. Prevents UV degradation if vials end up in light during transit.
Hand crimper tool
Required to seal aluminum crimps onto vial necks after filling. Manual hand crimper works for occasional use; sized to your vial neck (13 mm or 20 mm).
The quieter alternative: hard-shell vial cases
If your goal is "organize my peptides, prevent breakage, block light," you don't need empty vials — you need a hard-shell vial case. That's exactly what we make. VialCase is engineered specifically for 3 mL and 10 mL peptide vials, with insulated, light-blocking, organized slots.

Frequently asked questions
Are empty sterile vials legal to buy on Amazon?
Yes — empty sterile vials, including 2 mL, 3 mL, 5 mL, and 10 mL Type I borosilicate glass vials with rubber stoppers and crimp seals, are widely sold for laboratory and research use. They are not pharmaceuticals, and no prescription is required.
What kind of stopper should peptide vials have?
Look for chlorobutyl or bromobutyl rubber stoppers — they have low extractable content and reliably reseal after needle punctures. Avoid silicone or latex stoppers for any preservative-containing solution.
How do I store reconstituted peptides safely?
After reconstitution, refrigerate vials between 36-46 °F (2-8 °C), protect them from direct light, and keep them upright in a padded or hard-shell case to prevent cracking. Most BAC-preserved vials are considered usable for about 28 days; follow your prescriber's guidance.
Why use a hard-shell case for peptide vials?
Glass peptide vials crack easily — a single drop on a hard floor can ruin an entire month's supply. A precision-cut hard-shell case (like VialCase) keeps multiple vials upright, isolated, and protected during home storage and travel.
