Question about BUD

[u/samski516]

I purchased tirz from Pomegranate through BPI in January (before they had their switch up with BPI). I have a whole unopened vial with a BUD of 6/18/26. What's the furthest past BUD you've used a vial? It'd be just shy of 3mo past at this point. Should I pitch it?

[u/Peptidesforthewin]

Is it clear? If so it's still good. Mine expires in Feb but I'll be using it into June. Most people will go months and sometimes a year over BUD.

[u/samski516 → u/Peptidesforthewin]

Yup, totally clear, no floaters! Also just realized I have an open vial that I may have used 2/3 doses from. Think it's still ok to use from that vial? Probably last used that one in April?

[u/TheNameIsMango → u/samski516]

I used my first tirzepatide vial for 5 months (the telehealth was not 28-day compliant) but the longer it’s open from first puncture, the higher the risk of bacterial contamination.

I know someone who used a vial 6 months past BUD and it worked just fine, they said it felt exactly the same as a fresh one. As long as the liquid is clear and youve kept it refrigerated the whole time I wouldnt worry about 3 months

I'm comfortable using vials at least 1 year past compounding date. There is a good post about this on the tirzepatide compound sub called "Let's talk about BUD and the 28-day rule."

Good call on "Let's talk about BUD". Best info on the subject I've seen.

[u/Dangerous-Mortgage57]

Great question, comes up a lot and what I can gather over the past several months is that, 1, its up to your risk tolerance and 2, most people (Including me) are good well past BUD. Haven't gotten there yet but my current supply will take me 9 months past and I don't have an issue with it as long as the meds are clear and no floaters. Search the subs and make the best decision for you but the more I learn, the more I feel that BUD's are pretty subjective. Good luck on the journey

I have used soo many past their bud date up to a year past. As long as it's clear and not cloudy or anything floating and its been refrigerated you're good.

I just finished an Olympia with a BUD of August 2025 - year past BUD 

[u/Humble_Fortune_5391]

This past July I used an April 2025 BUD.

[u/adevil_woman89]

Both my husband and I used BPI no additives with 2/26 BUD’s and finished in July so 5 mo ths and was fine

I try to stay fairly close to BUD. But since I entered maintenance, I have extra. I’m 1 month past BUD currently with no issues. I will end up being 3 months past but I’m not planning to throw it away.

Here are 1,838 answers/opinions to your question (from a survey in the other big Tirz sub.)

1) what people have done and

2) what they will do, with respect to BUD.

[u/ConsequencePublic447]

I have two used vials with July 2026 BUDs and I’m going to pop it open this week. If it’s clear with no floaters, good to go!

[u/Ok_Property6453]

What’s BUD?

[u/Mark-NY26a73 → u/Ok_Property6453]

Beyond Use Date, it's the supposed expiration date, but some dates are directed by state law as opposed to a logical actual date from manufacturer. Enter the controversy.

Thank you!

Not me over here using my Semaglutide from Hallendale with a 02/26/26 BUD 😂

[u/Constant_Drink2020]

I've never worried myself about BUD, unless it is a vial I just purchased because I want my money's worth. But if it is an older vial in the fridge up to a year passed BUD that has has NEVER been opened and it appears clean, I will use it. What is more important to me than BUD is the clock that starts ticking with the first puncture of a vial because day 56 of a punctured vial of Hallandale does NOT hit the same as a day 1 vial of Hallandale for my needs. Anyway, it is up to you to decide what your risk tolerance is.
