There's no clear consensus on this. Like me, plenty of people think that the number of manufacturers is small while the number of vendors is large. When I track cap colors alongside COAs coming from various vendors, they strike me as samey samey. A different view holds that COAs, batches, and cap colors are all subject to manipulation. Which side is correct? What method would let us know with certainty? That's the big dilemma.
Suppose the reason you're asking is that certain vendors' R10s with yellow caps came back from testing looking "good," and your own vendor also carries R10s with yellow caps—does that mean you're in the clear? I suppose it comes down to how much faith you have in your luck that day. According to Peppy's, cap colors are assigned at random and may even shift inside one batch. Others put more weight on them.
The cloudiness problem that recently hit R20, caused by too much TFA salts residue, involved THREE distinct cap colors: purple, blue and red. So if you're thinking of leaning on cap color, how lucky do you feel?

Appreciate the response. To be honest, I’ve only placed a handful of orders so far and I’m still figuring out how all of this operates. When I noticed vendors offering products with matching cap colors, I figured that meant they were sourcing from one and the same place.
As it happens, I’ve signed up for a couple of testing groups for peptides I’ve already gotten, and I’m also looking for people to join one for another pep that’s still on its way to me.
I get that a third party coa can help lower the risk, but even within one batch there’s always the chance of problems or risk.
Thanks once more. This new adventure comes with plenty to learn.

As many have pointed out, there's a strong chance—perhaps even a probability—that they share a common origin, but you shouldn't take that for granted.
My suggestion: dig into everything you can find about any vendor you're considering, confirm they run an active Discord, and get involved there—or at minimum, stay current with the group's testing outcomes. The most reliable vendors tend to be steady and will back what they sell.

You're making good progress!
My take is that cap colors tend to be assigned without much pattern, and the number of actual manufacturers and finishers out there—across the whole market, not only this community—is much smaller than the masses of sales reps would make you think.

For my part, cap color isn't something I go by.
Did I ever do it? Sure, one time — though that comes with a major caveat.
What happened was I was aware of someone else who had purchased the identical product from the same seller at roughly the same point in time, and they were kind enough to post their test results for everyone in the group.

In my view, the colors on these caps don’t carry any real significance. To the manufacturer they might serve a purpose—perhaps blue indicates a Tuesday batch—or they could simply be whatever shade happened to be in the machine that day. The fact that certain vendors will let you pick your preferred color for an extra charge makes it pretty clear they aren’t meaningful.

All 3 peps in 1 order of mine turned up with the same white cap. Word is that several other peps out of that US warehouse carried white caps in the same stretch, so the color told us very little.

A cap's color can serve as 1 clue that a peptide comes from the same production run. When 2 individuals purchase the identical item from the same seller within a similar timeframe and the cap color matches, it's probable that they're dealing with the same batch. In cases where we're aware that vendors share their supply chains—such as WBS and ERP—then once again, matching cap color, product, and timing suggest the same batch.
That said, earlier this year multiple vendors were offering T30 with orange caps. Issues arose with the Jeep batch, but those from ERP/WBS came from different sources and had no problems. Consequently, people scrutinized any T30 with an orange cap very closely, since it might have signaled shared sourcing.
So it's not without significance, but you need to be cautious about how much significance you read into it.

Yes, this thread is a bit dated, but based on what I've picked up from working with Chinese manufacturing more broadly, I wouldn't be shocked if several sellers occasionally source from the same small group of factories.
Many of the sellers in this space aren't employed by the factory itself. A large number are trading companies or intermediaries who maintain ties with various manufacturers. That setup isn't inherently problematic. Across plenty of industries, the factory might lack English-speaking salespeople, international support staff, or any way to serve small overseas buyers directly.
So if a few vendors show up with similar packaging, caps, COA layouts, or timelines, that could point to a shared manufacturer — or it could simply mean they buy from the same packaging suppliers. Cap color by itself likely can't confirm or deny anything.
What I take from this: a vendor's reputation, consistency, testing practices, how they handle problems, and their level of transparency probably carry more weight than trying to work backward to the source using cap color. Coming from the same source doesn't guarantee the same quality control, storage, shipping, or accountability.
I'm still learning, but that's my current understanding.

Absolutely. Many of the Group Promotion Vendors source from the same suppliers.

Tracking cap colors that show up across several vendors still strikes me as worthwhile. Usually the COAs line up pretty closely.
My take is that JEEP was manipulating cap colors from their new supplier so everything looked identical, which let them cut testing costs. That bet wrecked their reputation.
