Peptidescores order went smooth, adding my data point

Anyone got a recent COA from them, or are we still looking at the same batch from last year? Also curious if shipping is domestic or overseas, and whether tracking actually updates.

New account, low post count, and a sudden wave of praise? I'll wait for a third-party test posted by someone who isn't brand new. Call me cautious.

What's the minimum order these days? Last time I checked, shipping was almost as much as a small vial, which killed the value for me.

I'm just here for the COA soap opera. Popcorn's ready, but the lab results are still buffering.

Watching this. Not ordering yet, but keeping an eye on whether people actually receive tracking numbers and clean COAs.

Does Peptidescores ship discreetly, and do they combine orders? I hate paying separate shipping on two tiny items.

COAs are easy to fake. Are these from an accredited lab with a verifiable URL, or just a PDF with a logo pasted on top?

Following. If anyone gets a pack and posts a redacted label plus lab link, you'll be the forum hero of the week.

Ordered last month. Vial label had lot and expiry, but the product page didn't expose lot until after checkout. COA posted was a summary: HPLC method + purity %, no chromatogram or MS spectrum, and no lot-linked archive I could search. That's the gap for me. Can anyone confirm if they now publish full traces and a per-lot lookup, or is it still current-generic? I track freezer temp and reconstitution dates; without lot-matched docs, it's just vibes.

Thanks for sharing—did the COA link back to a third-party lab you could verify?

The gap I keep hitting: are the COAs lot-specific or just “representative”? I keep a spreadsheet of batch, date, and how I felt, so a generic COA breaks the paper trail. If anyone has a recent pack, can you confirm the vial lot matches the COA batch, and whether the COA shows the actual chromatogram/MS spectrum rather than just a “≥98%” summary? That’s the detail I’d want before trusting any listing.

I’d want to know if their catalog uses stable SKU IDs and archived COA permalinks, not just live PDFs that get swapped when a lot changes. My sheet tracks quoted mg, actual fill, purity, test date, lot, and cost/vial; if pages overwrite, my history breaks. Does Peptidescores expose a CSV/API or lot-level permalinks, and do COAs separate “date tested” from “date posted”? That’s the data gap I keep hitting, and it matters more to my trendline than a redacted label.

The piece I haven’t seen addressed: what does the actual COA report for mass accuracy? Does it show calculated vs observed monoisotopic mass and a purity method — e.g., area % by UV at 214 nm — with the chromatogram attached? I log batch-to-batch retention time and peak area in a spreadsheet; a COA without the raw chromatogram or spectral peak list isn’t much of a data point. If they only post a summary PDF, I’d treat it as marketing.

I keep a COA tab in my spreadsheet; lot-specific or it doesn't count for me.

Same — if it’s not lot-specific, it’s just decorative art in a PDF.

Yeah, if it’s not lot-specific, it’s just decor. I’ve been burned by pretty PDFs.

Following, because I’m nosy about specs too. One thing I’d want to see is whether the COA batch/lot matches the number printed on the actual vial label, not just the outer box. As

For what it's worth, i keep every lot COA too; my downloads folder is basically confetti now. 😅

I do a boring thing: photograph the vial label and first page of the COA, then log the lot in my tracking app with start date and any energy/sleep notes. If the lot number on the label doesn’t match the COA exactly—or the COA has no revision date—I pass. Curious if their batch search preserves old COA versions or just silently updates? That’s the part that gets me.
