Recent MedChemExpress orders - what's everyone's experience

Anyone ordered from them recently? Curious how long international shipping usually takes, and whether customs is an issue. Not asking for anything wild, just planning ahead.

Do their COAs list batch-specific HPLC and MS, or just a generic sheet? I like MCE's catalog but I want to see actual lot data before buying.

Prices seem mid-range. Has anyone compared their bulk discounts to other vendors? I'm not loyal to any one supplier, just chasing the best value.

Watching this. Interested in recent shipping times and whether packaging is discreet. Keeping an eye on the thread.

Light skeptic here: "in stock" sometimes means "we'll ship whenever." Hope someone posts a real timeline instead of vibes.

COA says purity, but does it include the date and method? Some vendors recycle documents. Not accusing, just asking.

If their shipping is as fast as their website loads, I'll be impressed. Otherwise, I'll just keep refreshing this thread.

Placed my first order with these guys last week and now I'm stuck in the waiting game. Curious where stuff actually ships from — domestic warehouse or straight from overseas? I've dealt with both and it changes everything: one landed in four days, the other sat in customs almost three weeks with zero updates. Do they send tracking right away or make you ask for it? And what's the packaging like — plain box, no labels, or does it announce what's inside? Not trying to get side-eye from my mail carrier. If anyone's ordered recently, what were your timelines? Just trying to figure out if I'm planning around a week or a month here.

Following this. In the trials I've read, residual TFA/endotoxin can matter more than headline purity, so I'd want those on a lot COA, not just HPLC. Also: is the listed price per vial or per mg, and are US tax/duty/hazmat or cold-pack fees shown before payment? I keep a dumb spreadsheet of lot numbers and energy/sleep notes, so consistency matters more to me than one clean COA. Sharp follow-up: has anyone actually seen the pre-payment fee breakdown, or does it only appear on the invoice?

Following, because I’m a log-everything daily-weigher type—noise is noise, but customs fees are real. Specifically: does their checkout auto-add any US duty/tariff on lyohilized powders, or does the courier

I’m a weekly-average tracker, so I try not to let one unusual day drive my decisions. On the vendor side, my concrete ask would be whether they will share a lot-specific COA before payment, not only after shipping. I also want to know if the vial label, packing slip, and COA all show the same lot code. If anyone has asked recently, did they provide that without a minimum order or extra fee?

I treat this like any supply chain: invoice, vial label, and COA need to share the same lot number, or batch-to-batch comparisons are just vibes. Concrete ask for anyone who’s ordered: does the vial label itself carry a lot, or only the cat. number? If it’s only the cat. number, my tracking sheet has one useful column and it’s the one that goes blank. Curious if their packing slip bridges that gap.

One thing I’d ask before ordering: do they provide the actual HPLC trace and method for the specific lot, not just a pass/fail COA? I’ve seen COAs where the lot matches but the chromatogram looks generic or from a different column method. Also check whether dry-ice/hazmat surcharges

I’ve been around since the old weekly check-in threads, and the detail that always bites people isn’t the listed price—it’s what happens in transit. Does MCE ship with a temperature logger, or at least cold packs that are still cold on arrival? And is endotoxin testing included, or is that a separate request? I ask because a couple of past vendor threads had great paperwork but rough shipping, and that’s the part I’d want nailed down before ordering.

I keep a spreadsheet for cold-chain arrivals: ambient temp at drop-off, gel-pack count, and whether the box still feels cold. Across three orders from them, two showed up with fully warm packs, and the storage label didn’t match the shipping label. That variable bends my cost-per-usable-vial trendline way more than posted price does. Do they offer a temperature-excursion record or a data logger on request? If not, I’d factor in replacement or dry-ice shipping before ordering.

Hi, I’m brand new here—literally week one—so sorry if this is a basic question. I didn’t see anyone mention back
