Anyone else notice S1Research switching up their stock

Following this one. Has anyone confirmed the COA batch numbers actually match the vials, or is it the usual copy-paste PDF?

What’s the current shipping ETA to the EU, and is it tracked? Not asking for a friend, asking for my refresh button.

Prices look mid-tier. Any bulk discount, or is the sale just permanent? Also, do they take anything besides crypto?

Lurking. I’ll believe the COA when someone posts an unedited timestamped test, not a screenshot with half the page cropped.

Anyone got a recent order timeline? Label created fast, actual movement took forever for me. Could be seasonal though.

Watching this thread like it’s a stock ticker. Someone ping me if the COAs get updated or the shipping drama starts.

First post, brand new account, and wow, that website sure is shiny. Nothing suspicious going on here at all.

Can someone clarify: is the price per kit or per vial? The site says one thing, checkout says another. COA link is also dead for me.

I track COAs in a sheet too; batch matching is the only thing I trust. Their listings made my pivot table cry.

Question for OP: do the COAs list method (HPLC vs LC-MS) and include endotoxin/residual solvent panels, or just a purity percentage? That’s my filter. I keep a log of energy, appetite, and side effects independent of vendor, and if a COA lacks lab name/date/lot, I don’t bother. Also confirm whether kits ship with ice packs or ambient—stability data matters more than a shiny checkout.

Plateau twin here—week 9 of the scale doing absolutely nothing, but my jeans are looser, so I’m trusting measurements and a food scale over the number. One thing I’d add to the COA checklist: don’t just match the lot number—check that any QR/link actually resolves to the testing lab’s own domain, not a PDF hosted on the vendor site. I’ve seen “COAs” with no lab contact, no sample receipt date, and a report date

If the lot isn't locked at checkout, the COA is basically a mood board. I screenshot the listing, checkout lot, and COA date into one folder; mismatch = no order. Sharp question for anyone who’s ordered recently: did the vial label lot match the COA lot exactly, or just the compound name? That’s the only version of “batch-specific” that survives a restock. Also, a COA dated before the current listing is a red flag, not a green one. Vendors rotate stock; docs don’t always rotate with

The “mood board” line killed me 😂 I screenshot lot + COA date too, otherwise it’s just vibes.

I track shipping, not just COAs. Last restock I logged order Tues 9pm, label created Wed, first USPS scan Fri, delivered following Mon. Two days later the same listing showed a different lot # and the COA date moved up. That makes me wonder if S1Research updates inventory in real time or just swaps the COA when a new batch lands. Do they show a quantity left, or only a generic “in stock” badge? If it’s generic, I’d screenshot the stock badge + lot at the same

I screenshot lot + COA date, then lose it in my camera roll anyway 😂

The thing I’d test first: whether the COA has a lab sample ID or QR/report number you can look up directly on the lab’s site, not just a PDF hosted on the shop. If the batch number only lives on the shop’s page, it’s not really verifiable. Also handy to ask if they’ll confirm the lot on the invoice/packing slip before you open anything—if the lot doesn’t tie back, I don’t bother logging it in my spreadsheet. Curious if anyone’s seen a lot flip mid-restock without a new COA posted.

One thing I’d ask them directly: is the COA tied to the exact lot shipping now, or just a representative batch? I’ve seen shops post a clean lab report with an old sample ID while current vials have a different lot. I track this like my lifts: lot + report ID + test date in a spreadsheet. If the sample submission date is months before the current batch, I treat it as stale. Do they show a sample submission date or chain-of-custody, or only the test date? That’s the gap I keep hitting.

The piece I’d wnt clarity on: does each product page show a “last updated” or restock date? I’ve compared shops where the catalog looked identical for weeks, but the actual lot had rolled over. Now I check whether out-of-stock items disappear or linger as preorder—that tells me if the listing is live inventory or stale filler. Has anyone asked them if the lot number on the product page updates with restocks, or only when someone remembers? That’s my make-or-break for comparing shops.

I’m with y’all on the COA rabbit hole, but the piece I keep running into is lot history. Does their site let you search by order number to pull the exact COA for what shipped? I keep a little spiral notebook—yes, paper, like our pharmacy’s old receipts—with order date, lot, and COA date, and if a restock switches lots mid-month I want to know whether the old COA is still archived or just disappears. Also curious if they email the CO

As someone maintaining now, I care less about restock hype and

The gap I’d poke at is fulfillment, not the website: if I order during a restock and the lot changes before it ships, do they automatically substitute, hold my order, or cancel? I keep a simple log of lot + COA date for anything I reorder, and I’ve learned to screenshot the listing at checkout because pages change fast. If their answer is “we ship current stock,” I’d ask whether the COA link updates before the order leaves. That’s the practical part for me now that I’m maintaining.

I’m less worried about the site labels and more about the quiet math: when S1 swaps stock, does the list price stay flat while kit size or total units per kit changes? I keep a spreadsheet of price per listed unit + shipping + payment fees, and that’s how I catch a “same price” restock that’s actually a 10–20% cost bump. If anyone has two recent orders before and after the switch, can you compare unit price and kit count? Not trying to dunk on them — just want the numbers.
