Protoflow Lot Number: What PRO-26/MY-3220 Means and How to Check a Bottle

Quick answer

The Protoflow lot number the seller gives is PRO-26/MY-3220, with CoA reference PRO-3220-26-MY. Both are seller references. We found no lab report, public lookup or factory record behind either, so they prove nothing about purity or strength. A real-bottle check rests on the label: 60 capsules, 14 printed lines, the Aurora distributor address and an intact seal.

The numbers01

What is the Protoflow lot number?

The seller's lot reference is PRO-26/MY-3220, and its CoA reference is PRO-3220-26-MY. Neither one is a lab result.

A lot number tells a maker which production run a bottle came from. A certificate of analysis, or CoA, is a lab's report on that run. A real pair lets a buyer match a bottle to a report and see what was measured.

Here the pair is incomplete. The references come from the seller. We could not tie either one to a lab, a factory or a printed report, and no public lookup exists that we know of. The bottle image we read shows no lot or expiry stamp, so we cannot say where yours is printed.

What it proves02

Does a lot number prove a Protoflow bottle is safe or real?

No. A code on a bottle shows only that the bottle carries a code. Proof needs a report from a named lab for that lot.

Anyone can print a code. What counts is whether a lab report exists, who signed it and what it measured. A strong report names the lab, the lot, the test methods and each result, such as ingredient identity and contaminants.

Under FDA's supplement rules, makers must verify the identity of each dietary ingredient component (21 CFR Part 111 (eCFR)). That is a duty on the maker, and the records stay with the maker. A buyer does not get to see them unless the seller shares them. So the practical step is to ask.

The question to ask the order desk

"Which lab produced the certificate for lot PRO-26/MY-3220, and can I have a copy?" Call +1 (302) 200-3480, then follow up in writing to [email protected].

A useful answer has four parts: the lab's name, the date of the test, the lot it covers and the results themselves. Ask for a copy you can keep. A reply that says the product is tested, with none of those four parts, does not move the question forward.

If the answer is a code and nothing else, treat the code as a reference number. The wider quality picture is on the testing and quality page.

About CoAs03

What should a Protoflow certificate of analysis contain?

A named lab, a lot, a test date, the methods and a result for each item tested.

A real certificate is specific. It lists what was tested, such as ingredient identity and strength, how it was tested and what the numbers were. It carries a signature or a lab seal you can look up. A bare reference code carries none of that.

For a 14-line capsule such as this one, expect a certificate to speak to identity at least, since the FDA rules call for it (21 CFR Part 111 (eCFR)). A strength figure for lines like saw palmetto would be the most useful number to see.

Real or fake04

How can I tell if my Protoflow bottle is real or fake?

Compare it with the label we read: 60 capsules, PROTO FLOW on a dark green label with a lime ring, 14 printed lines and the Aurora, CO distributor address.

We cannot authenticate a bottle from a photo, and we know of no public report of fake Protoflow bottles. A label check still catches the obvious problems. Work down the list with the bottle in your hand (Protoflow bottle label).

  1. The front

    PROTO FLOW with a lime ring, plus HIGH POTENCY, Day & Night Formula and Optimal Flow Support, each with the dagger where shown.

  2. The count

    60 capsules, listed as 30 servings of 2.

  3. The panel

    14 lines with amounts, from vitamin E 13 mg and niacin 75 mg to cayenne 20 mg, and a total near 1,619 mg.

  4. The other ingredients

    Rice flour, gelatin, magnesium stearate, silicon dioxide, maltodextrin, soy protein concentrate and water.

  5. The directions and distributor

    Adults take two capsules daily with water, and PhytoThrive Labs, 19655 E 35th Dr #100, Aurora, CO 80011 is named.

  6. The seal

    A bottle with a damaged or missing safety seal should not be used.

Warning signs05

What differences should make me stop and call the Protoflow order desk?

A different count, a missing panel, a vegan claim on the bottle, a missing distributor address or a broken seal.

A mismatch does not prove a fake, but it is enough reason to pause. Photograph the bottle first, front, panel and base, then call.

Wrong count or form

The real bottle holds 60 capsules. A bottle of drops, gummies or a different count is not the product we describe.

Panel does not match

Fewer than 14 lines, no amounts or a vegan claim does not fit the label we read. It lists gelatin and soy.

Seal broken

The label says not to use the product if the seal is damaged or missing.

A bought-elsewhere bottle deserves extra care. We know of no authorized Amazon, Walmart, CVS, Walgreens, Target, GNC, Costco or eBay listing, so a bottle from one of them may not be the real product. The where to buy page explains the one route we know, the Protoflow info page.

Next steps06

What should I do if my Protoflow bottle looks wrong?

Stop using it, keep the bottle and packing, photograph everything and call the order desk the same day.

Do not throw anything away. The bottle, box and shipping label are your evidence for a refund under the 60-day guarantee. Keep taking any prescribed medicine as directed while you sort this out.

  • Photograph the front, the Supplement Facts panel, the base and the seal
  • Write down where and when you bought it, and the order ID
  • Call +1 (302) 200-3480 and ask about the lot and the return steps
  • If the product made you feel unwell, tell your doctor and report it to the FDA Safety Reporting Portal (FDA, Dietary Supplements Q&A)
  • If you paid a marketplace seller, ask your card issuer about a dispute

Return and refund steps are on the refund policy page. Phone and email details are on the order help page.

What we can do07

Can the Protoflow website verify my bottle for me?

No. We are a retailer's information site, not the maker, and we hold no production records or lab files.

We can compare your description with the label we read, and we can point out what does not match. We cannot confirm a lot, trace a shipment or release a lab report, because we never held one. The order desk and the distributor on the bottle are the only parties that can.

If you find a mismatch with our figures, write to [email protected] with photos. We check it against the label and correct any page that is wrong. See the contact page for the full list of routes.

FAQ08

Protoflow lot numbers, short answers

Can I look up PRO-26/MY-3220 online?

We found no public lookup for that code, on the seller's site or anywhere else. It works as a seller reference. If you want it matched to a run or a report, ask the order desk by phone and again in writing.

Is PRO-3220-26-MY a lab report number?

Not as far as we can show. The seller lists it as a certificate reference, but no lab, date or result sits behind it in anything we could read. Until a named lab and a report are published, it stays a seller reference.

Do fake Protoflow bottles exist?

We found no report of counterfeits, and we cannot rule them out. Any popular supplement can be copied. A bottle bought from an unlisted marketplace carries more risk, since it may not come from the info page route.

What should I photograph before calling about a lot?

The front, the Supplement Facts panel, the directions panel, the base and the seal, plus the shipping label. Lay the bottle on a plain surface in good light so the print is readable, and note the order ID.

Does the bottle carry an expiry date?

The bottle image we read shows none in view. Check the base and neck of your own bottle. If you cannot find a lot or expiry code, tell the order desk and ask for it in writing before you start the capsules.

Does a matching lot code mean the capsules are the right strength?

No. A match shows that two codes agree. Strength is shown only by a lab test of that lot, and none is published. The label says 84.5 mg of saw palmetto, and nobody has shown that a capsule holds it.
