I get this question a lot, so let's clear it up once and for all. What is Hospira bacteriostatic water? Hospira is the name-brand version, formerly made by Pfizer, and it's the same bacteriostatic water used in hospitals. If it has the pink top, a lot number, an expiration date, and all the Hospira branding — that's the real deal. Same product medical professionals are using. What about off-brand bacteriostatic water from peptide companies? Some peptide vendors make their own reconstitution solution. If you go this route, I'd recommend using one that's been tested — like the bacteriostatic water from EZ Peptides. The test confirms there's actual benzyl alcohol content in the solution, which is the key ingredient that keeps your peptide stable for roughly 6–8 weeks after reconstitution (sometimes a little longer). The simple way to think about it: This is just name brand vs. off-brand. Both can work. But if you've ever had issues with your peptides degrading or losing potency faster than expected, I'd recommend just going the Hospira route. It's a little pricier, but the peace of mind is generally worth it. TL;DR: - Hospira = hospital-grade, Pfizer-made, pink top, lot number + expiration date - Off-brand = works fine if it's tested for benzyl alcohol content - Had issues before?

What are the differences in participant levels? I noticed they go from 1-9. Thank you!

Does reconstituting Cagri need acetic acid? I read some posts on other forums where people recommended using acetic acid to avoid gelling and more importantly "micro fibrilation" that can cause adverse immune response.

This one's been a long time coming, and I'm pumped to finally share it with you guys. Starting today (February 12th), every peptide on the site is being price tracked daily, rolling over a 90-day window. You can now see exactly how prices move over time — no more guessing whether you're catching a deal or paying a premium. Here's what you get: 📈 Interactive price history graphs — hover over any data point to see exact prices by date and vendor. Company logos are built right into the charts so you can quickly spot who's cheapest. 🔀 Filter however you want — toggle between with discount codes or base prices, switch between total price and price per milligram, and filter by specific vendors. 📊 Raw data table — every vendor, every day, laid out so you can see the full picture. Lowest, average, and highest prices all at a glance. 📱 Works on mobile too — same features, optimized for your phone. Look for the new little icon next to products — hover over it and click "View Price History" to check it out. I backfilled 30 days of data to start, and from here it tracks forward daily. 20,000 lines of code went into the backend for this, so if something breaks, bear with me — but I'll keep it as accurate as possible. I'm already tracking all of this for you guys anyway, so why not make it visible? Might even add a CSV export option down the road. 👉 Go try it out: peptideprice.store Watch the full demo walkthrough here: https://vimeo.com/1164525504/131573bed7 Let me know what you think! PeptidePrice is nothing without you guys — appreciate all the support as always. 🤝
