Extended use and storage of opened bacteriostatic water beyond 28 days

Apologies, I wanted to indicate that an alcohol wipe should be used for cleaning. Air will be pulled into the bottle to balance pressure when removing the solution, but 0.9% benzyl alcohol is present to stop any bacterial growth.

I've noticed this lasts around three months showing very little breakdown. It stays in a cupboard that's kept cool and away from light.

Anyone heard of that brand of BAC?

Manufacturers based their twenty-eight day guideline on experiments conducted in particular setups. Once it succeeded in those tests they were only permitted to state that officially. It doesn't imply spoilage starts exactly then. The benzyl alcohol at point nine percent in the solution is there specifically to stop microbes from multiplying. With fresh needles each use avoiding pushing air into the container and keeping it cool and dark I find three months works fine for me.

I'm puzzled why folks put the mixed peptide in the freezer if the diluent needs to stay away from light at room temp and cold temps break it down.

Whenever I mix up my solution, I pour in the entire amount of the sterile water. The process happens within a clean, sealed workspace that I've sterilized. Before and after handling, I clean the surfaces of the containers with rubbing alcohol. Once done, everything goes into the refrigerator inside another sterilized holder. I'm okay going beyond the usual month if the liquid stays clear without any bits floating around.

That month-long guideline comes from broad FDA rules about containers meant for repeated use. I ignore the whole thing since the mixture of water and alcohol stays good indefinitely. I always grab fresh needles and clean the tops with alcohol each time, so the risk of germs getting in seems pretty small. Recently I began using peptides again following a long pause of several years, and the containers I'm drawing from now are the ones I had sitting around for more than two years.

Everyone else pointed it out too, so once I open the container I store it inside the refrigerator where it stays fine if it looks transparent. A batch from two months back gave me no trouble at all.

I keep going with it day after day until the container has nothing left inside. Normally the supply lasts me anywhere from six weeks up to two months.

The printed dates on those vials strike me as mostly for the sake of selling the product, provided the tiny containers stay sealed away from outside air and never get touched by a dirty needle. Eye cream labels, for example, often warn you to throw the tube out after ten days once opened. I once had to grab something in a rush and the only tube sitting around was already three years past its date. My sore eye cleared up fine with no vision trouble.
