Not much out there on Particle Peptides (particlepeptides.com), so I'm digging a little. Slovakia-based, 7 items in the catalog, prices published, shipping info published, COA documents posted — though only one I can find verified anywhere online. That last bit is what's bugging me. Which 7 products are actually listed right now, and how often do the catalog and prices get updated when stock or a batch changes? Do batch-specific COAs exist for every product before you order, and which analytical methods and third-party labs are named? If only one COA is verified, does that mean the rest of the current batches don't have one? Shipping from Slovakia: where do they send, how long does it take, how's it packaged, is there tracking, and who eats customs and duties? And are published prices VAT and shipping included or not — do they change by destination, payment method, or order size?
Checking Particle Peptides COAs by batch number

Anyone know if they ship internationally, and what carrier they use? I’m just curious about typical transit times and whether tracking is included. Not in a rush, but I like knowing before checkout.
#3
Did anyone receive a recent COA? I’m mainly interested in whether the batch numbers match the vials and if the testing lab is named. Just trying to compare documentation styles.
#4
Prices seem mid-range from what I’ve seen, but the minimum order is the real question. Is there a flat shipping fee, or does it scale? Also, any discount codes that actually work?
#5
Watching this thread. I’ve seen the name pop up a few times but haven’t ordered. Curious if folks get replies to emails within a day or if it’s more of a vibe-based support system.
#6
Skeptic here: every vendor looks great until you ask for a COA with a verifiable lab contact. If they can’t provide that, I’m out. Otherwise, curious to see follow-ups.
#7
Their site says 'research use only' about forty times, which is fair, but I still can’t find a clear shipping table. Anyone have a screenshot of checkout options?
#8
I asked for a COA and got one, but the PDF metadata looked like it was made at a copy shop. Not saying fake, just saying I’d want the lab to confirm. Anyone else notice that?
#9
Haha, 'Particle Peptides' sounds like a band that only plays in lab basements. Anyway, following for shipping updates and whether the packaging is discreet.
#10
I weigh daily and only trust the 7-day trend, so I’d apply the same rule here: one COA PDF isn’t a trend. The concrete thing I’d check is whether the batch number on the COA matches the batch number on the actual label/vial, and whether the COA date fits the production window. If they only post one generic COA per product, that’s a single noisy data
#11
I weigh daily and only trust my 7-day average, so I’d apply the same patience here: one batch’s COA is just a data point. The useful follow-up is whether the lot number on the vial matches the COA exactly, not just the product name. Does the report name
#12
For what it's worth, that copy-shop PDF metadata is the plot twist nobody asked for.
#13
Honestly, i’ve been trying to apply my new empty-nester patience here: morning walks, actual cooked dinners, and not chasing every shiny label. For peptides, the thing I’d check next is
#14
Systems take: a COA with no batch-to-order linkage is a dangling foreign key. Decorative, not verifiable. Do their invoices/packaging show a lot number that matches the posted COA filename? If not, that’s the actual finding. I keep a dumb spreadsheet for my own stuff—date, lot, sleep, steps
#15
I’d look at COA dates, not just the count. If all seven were issued the same week, that’s a launch panel, not an ongoing testing rhythm. Also check their sitemap or an archived shop page—catalogs shift quietly. Which seven are you seeing right now? I’ve been applying my new empty-nester patience to this: coffee, a notebook, and one rabbit hole at a time. If the PDFs aren’t date-stamped, it’s like my old recipe cards—can’t tell current from 2019.
#16
This is the part I’d chase: does the COA have a lab-issued report ID you can verify on the actual lab’s own portal, not just a PDF hosted by the vendor? I got burned once—perfect-looking COA, but the lab had no record of that report number. If anyone has one of the seven, drop the lab name and I’ll run it. Also, do they list excipients/capsule materials? For recomp tracking, that matters more to me than a shiny purity number.
#17
One thing I’d add: does the COA include an actual chromatogram image with axis labels and an integration table, or just a typed purity percentage? In real lab reports I’ve seen, the peak area, retention time, and sometimes mass spec panel are visible. Also check if the vial crimp has a lot number stamped on it that matches the COA batch—if not, there’s no way to tie the report to what’s actually in the box. Did you ask them for raw data files, or just the PDF?
