I came across some actual lab-tested degradation data that genuinely shifted how I think about storing reconstituted peptides, and I figured it was worth sharing here.

The testing was done by an independent group through a chemical analysis lab, tracking degradation at 30, 60, 90, and 120 days post-reconstitution. A few things genuinely surprised me:

Some compounds held up remarkably well for months when kept refrigerated — way more stable than I would have guessed. Others fell off faster than I expected. Even Hospira bacteriostatic water was included in the testing, and while there was measurable change over time, it wasn't as dramatic as you might fear — provided you refrigerate it after opening.

The biggest thing this hammered home for me is that there's no single storage rule that applies across the board. Treating every reconstituted peptide the same way in the fridge is a real mistake if you're trying to preserve potency.

What I appreciated most was seeing actual percentages from a controlled lab setting rather than forum speculation or the usual bro-science passed around. If you're reconstituting anything and just assuming it's holding up fine for months, this data is worth a close look.

Big news dropped on February 27, 2026 — RFK Jr. went on Joe Rogan and said roughly 14 of the 19 peptides the FDA restricted back in 2023 are being moved back to Category 1 status. That would mean licensed compounding pharmacies can prepare them again under a physician's prescription.

The 14 reportedly coming back include BPC-157, TB-500, Thymosin Alpha-1, CJC-1295, Ipamorelin, AOD-9604, Selank, Semax, KPV, MOTS-C, GHK-Cu, and a few others.

The 5 that are staying restricted: Melanotan II, GHRP-2, GHRP-6, LL-37, and PEG-MGF.

Now here's where I want to pump the brakes a little, because I'm seeing a lot of people misread what this actually means right now.

No formal FDA rule has been published yet. The PCAC review meeting is scheduled for July 23–24, 2026 — that's when formal implementation is supposed to move forward. So legally, we're still in a transitional gray zone until that happens. None of these compounds have FDA approval. A physician prescription is still required for any compounded version. And honestly, the quality verification piece matters more now than ever — unregulated sellers are already using RFK's statements as cover to push products with zero quality oversight.

The direction is encouraging, but implementation is still pending. COA standards haven't changed just because someone made an announcement on a podcast.

Curious where others are at with this — has this news shifted how you're thinking about your research planning, or are you holding off until the formal rule actually gets published?

Honestly tried a pen for one of my daily injections and that was it — syringes are dead to me now.

Yeah I always filter mine — it's cheap peace of mind and makes me feel a lot better about using them over an extended period.

I've done a pretty thorough search through as a whole and picked up quite a bit of info, but I want to hear what people are actually doing in practice. My current plan is to take Zyrtec about 30 minutes before injecting and apply some Benadryl cream directly on the injection site. I also came across mentions of Flonase being part of some people's approach. What's the full protocol you're running? Looking for something real and tested, not just theoretical. Appreciate any input!
