Needle Free Vial Adapters (Vial Spikes)

Summary

Are needle-free vial spikes worth using on BAC water or other multi-dose vials?

Users report trying spikes mainly on BAC water vials for easier repeated access, with some extending the practice to TRT vials containing oil. Several note the devices can be fiddly to seat properly and may compromise the rubber stopper seal, making them better suited for short-term use rather than long storage. Opinions split on whether the added convenience justifies any extra cost or risk, and a few mention switching back to standard needles after testing.

This caught my eye. I think I'd want one for my bacteriostatic water.

I put them on both my TRT vial and my bac water. They don't match the three shown but they work well for me.

I'm puzzled about the real benefit here. How does paying more improve things specifically? Sure, it limits the vial to a single needle entry, yet I wonder if repeated entries into a resealable container cause any real trouble. When moving liquid into a pen, that only requires one or two entries total. Perhaps something like that works for the water used to mix, but not much else.

This only seems useful with the preserved injection water and nothing else really fits. Sanitizing covers for the needles are out there and I'd grab some if I end up using it.

A while back I picked up these spikes since they looked intriguing at the purchase time. I examined them but never got around to testing them out. The primary cause I skipped using them with my BAC vials comes down to the fact that my solid six-compartment storage container top for holding the BAC wouldn't shut properly when that device sat on the vial tops. It was essential to maintain the BAC vials inside a dark solid container. Those spikes really amount to nothing more than a fun concept.

I'm on the same page here. This would only go with my BAC. I went ahead and got some. Perhaps I'll check in later about whether it works for me and what it ends up costing. ADD makes handling money tricky for me.

Wow what a ramble-fest? That video could have or should have been five minutes long.

It's unfortunate how extended clips end up packed with extra commercials before during and after everything. That setup just pulls in additional revenue overall. Even so sometimes creators fail to stay concise and ramble on instead.

I use them on my BAC water. Yes, I like them.

Thank you for the info.

Maybe you need a VPN and change your address or IP to the USA and maybe get ad blockers. I never see ads, ever.

Also very good links, thank you.

Getting a hole in it proved tricky for me and required precision. The opening needed to be perfectly straight and in the middle otherwise the top wouldn't fit properly. Even then the top didn't seal right. Perhaps the flat head type would work better than this one. I tried it only after taking the final amount from my container. The closure left me disappointed. Instructions indicated it wasn't meant to keep things long term but rather to allow repeated entries during one use period. A reference mentioned keeping things clean for just a week instead of a month so I figured a month instead of three. I think skipping it is best though you shouldn't listen to what I say. Also starting with a large quantity isn't smart. Plus it damages the stopper making reuse impossible. Update: the size I used was the compact one for that container.

So these can be used for oils? If so I'll buy some now.

I've been relying on these for quite some time, and they've performed really well for my needs. They shine particularly when I administer them every day as I do. Drawing into the needle becomes much simpler than with alternatives. I always include a small air pocket at the top of my measurement to expel every last drop, since the tiny amount left behind in the connection accumulates throughout the week. I'm aware some folks advise against combining them with oil-based stuff, yet I've encountered zero issues like breakdown or malfunction. My larger containers have held up fine over extended periods at my dosage level, remaining transparent without any signs of damage or haze.

I have extensions installed to block advertisements and harmful websites both in my browser and on my entire network. There's also a tool I use for skipping promotional parts in videos. Advertisements don't appear for me anymore, though I get why video makers stretch out their content. I tried accessing the website through a virtual private network once. Even so, my location means they don't deliver here. A forwarding service could help, but they usually won't handle anything health-related. I get my sterile water from the same place I buy the other items, and it's always worked fine. Trusting the main products from overseas but questioning the water seems inconsistent to me. That's just how I see it.
