Hulk Bars, B707, and White Xanax Bars: Real Imprints vs Pressed Pills

The rule that comes before any imprint

An imprint identifies a pill a pharmacy dispensed. It does not identify a pill that came from a friend, a dealer, a social media account, or a website. Counterfeit bars are pressed to copy the real imprint, score lines, and color. The DEA’s One Pill Can Kill page says it plainly: “Never trust your own eyes to determine if a pill is legitimate. The only safe medications are ones prescribed by a trusted medical professional and dispensed by a licensed pharmacist.”

Everything below is for identifying a bar from a pharmacy bottle, or for understanding what a name means. None of it can clear a bar that came from anywhere else.

What is a Xanax bar?

A Xanax bar is the 2 mg tablet of alprazolam, a Schedule IV benzodiazepine. The brand tablet, per the XANAX prescribing information, is white, oblong, and multi-scored, imprinted “XANAX” on one side and “2” on the other. The score lines let it break into four pieces, which is where the bar, ladder, and plank names come from. Lower strengths are not bars: brand 0.25 mg is a white oval, 0.5 mg a peach oval, 1 mg a blue oval.

The DEA’s fake prescription pills fact sheet lists the street names for Xanax: bars, benzos, bicycle handle bars, bicycle parts, bricks, footballs, handlebars, Hulk, ladders, planks, school bus, sticks, xanies, yellow boys, zanbars, zannies, and Z-bars.

Real 2 mg alprazolam bars, by color

Generic alprazolam 2 mg bars are made by several companies, and they do not all look alike. These are the immediate-release 2 mg tablets described in labels on DailyMed, the National Library of Medicine’s database of FDA drug labels, as of October 2026.

Two things follow from the table. Color does not tell you strength: real 2 mg bars come in white, yellow, blue, and green, and lower strengths of alprazolam also come in white, peach, yellow, blue, and green. And color does not tell you real from fake, because every color on the list can be copied. The extended-release and orally disintegrating forms of alprazolam are round or shaped tablets, not bars.

Hulk bars and green Xanax

“Hulk” is on the DEA’s list of Xanax street names, and in street use it refers to a green bar. Green 2 mg alprazolam bars do exist from a pharmacy: N 51 1, and on an older DAVA label, S 90 3, in the table above. Green does not mean stronger. A green bar from a pharmacy is 2 mg of alprazolam, the same as a white one. A green bar from anywhere else is an unknown.

What is the B707 pill?

B707 is a real imprint: a light blue to blue, rectangular alprazolam 2 mg tablet with three breaklines and two notches, distributed by Breckenridge Pharmaceutical, per a repackager label on DailyMed. The same company’s 1 mg tablet is a blue oval stamped B706. A B707 bar that is white, green, or any color other than blue does not match the label.

White Xanax bars and “Xanax bars 2mg”

White is the most common color among the 2 mg bars in the table: the brand, G3722, GG 249, the Aurobindo bar, and the Natco bar are all white. That is exactly why white bars are what counterfeit presses copy. The DEA says fake pills are made to look like prescription drugs including alprazolam, and that cartel labs press them to look identical to the real thing.

School bus Xanax and yellow bars

“School bus” and “yellow boys” are DEA-listed street names for Xanax, and in street use they refer to yellow bars. The real yellow 2 mg bar on DailyMed is R 039 from Actavis. Yellow is also the color of some 0.5 mg alprazolam ovals, which is another reason color is a poor guide to dose.

Red Xanax and other colors

None of the 158 alprazolam labels we reviewed on DailyMed in October 2026, at any strength or in any form, describes a red, pink, or purple tablet. A red bar does not match any alprazolam label we found. Treat it as counterfeit.

What is actually in a pressed bar

You cannot know without a lab, and that is the point. Two things have repeatedly turned up.

• Fentanyl. Of the fentanyl-laced fake prescription pills the DEA laboratory analyzed in 2022, six in ten contained a potentially lethal dose, up from four in ten in 2021, per a DEA public alert. The DEA counts 2 mg of fentanyl as a potentially deadly dose, and says it seized more than 47 million fentanyl-laced counterfeit pills in 2025.
• Designer benzodiazepines, especially bromazolam. Bromazolam has no accepted medical use in the United States. The DEA placed it in Schedule I by a temporary order effective March 16, 2026, which says it “is often encountered in pill form and can be made to mimic the appearance of legitimately prescribed substances, such as alprazolam.” The order counts at least 259 overdose cases involving bromazolam from April 2021 to February 2026, 201 of them fatal, with fentanyl also present in 78 percent. It also cites a CDC report of three previously healthy young adults who took pressed bromazolam tablets they believed were alprazolam and developed seizures, high blood pressure, and heart injury.

The scale of the shift is visible in CDC data. In a 2021 MMWR report covering 2019 and 2020, deaths involving illicit benzodiazepines in 23 states rose from 51 to 316 (519.6 percent) between the second quarter of 2019 and the second quarter of 2020, and 92.7 percent of benzodiazepine-involved deaths in the first half of 2020 also involved opioids. Benzodiazepines and opioids together are the combination the XANAX label’s boxed warning names first: profound sedation, respiratory depression, coma, and death.

Test strips and naloxone

Fentanyl test strips have been legal to possess and hand out in New Jersey since January 8, 2024, when P.L.2023, c.224 removed drug-checking supplies from the state’s paraphernalia law, per a NJ Department of Health memo. A fentanyl strip only answers the fentanyl question. A negative result says nothing about bromazolam or the actual dose. Naloxone belongs anywhere pressed bars are, for the same reason; our naloxone guide covers where to get it free in New Jersey.

“Mexican Xanax” and Farmapram

Farmapram is a brand of alprazolam, the drug in Xanax, sold in Mexico; Mexican pharmacy listings show it requires a prescription there. “Mexican Xanax” is what people call alprazolam bought at a Mexican pharmacy, often near the border or in tourist areas.

The problem is not the brand name. It is that a pill bought over the counter, without a prescription, may not be what the box or the clerk says. In a 2023 study in Drug and Alcohol Dependence, researchers asked for “oxycodone,” “Xanax” and “Adderall” at 40 tourist-oriented pharmacies in four cities in northern Mexico. At 28 of them, at least one controlled drug was available with no prescription. Of 45 pills sold as controlled drugs, 18 were counterfeit: 8 of 27 “oxycodone” pills contained fentanyl, 3 contained heroin, and 7 of 11 “Adderall” pills contained methamphetamine. The researchers could not tell real from fake by looking, because identical-looking authentic and counterfeit pills were sold in the same neighborhoods.

Bringing controlled medicine back is regulated too. Federal rules require declaring controlled substances to customs, in the original container, and limit how much a U.S. resident can bring back for personal use without a U.S. prescription (21 CFR 1301.26). This is general information, not legal advice.

How to tell if a Xanax bar is real

Only one way works: it came from a licensed pharmacy, in a labeled bottle, filled on a prescription in the patient’s name, and the imprint, color, and shape match the label for that manufacturer. If you are holding pills from a pharmacy bottle and are unsure, the pharmacist can confirm them. Imprint lookup tools are useful for that and useless for anything else. A bar that looks perfect is not proof of a real one.

Regular bar use and withdrawal

Someone who has been taking bars regularly, real or pressed, may be physically dependent. The XANAX label warns that abruptly stopping or rapidly cutting the dose after continued use can cause acute withdrawal that can be life-threatening, including seizures. Pressed bars make this harder: the person does not know their real dose, may be dependent on a designer benzodiazepine with a different half-life, and may have taken fentanyl without knowing it. A clinician needs that history, and lab testing at intake can help show what was actually taken.

If you take alprazolam on a prescription, do not stop on your own. Talk to the prescriber about a taper. If you have been buying bars and taking them regularly, do not stop suddenly either; get a medical assessment first. Our Xanax withdrawal guide covers what withdrawal looks like, and the benzodiazepine detox guide covers how New Jersey programs manage it. If opioids are part of the picture, the polysubstance detox guide explains why both have to be treated together. If someone is having thoughts of suicide, call or text 988.

In New Jersey

Under New Jersey law P.L.2017, c.28, fully insured New Jersey plans and the State Health Benefits and School Employees’ plans cannot require prior authorization for the first 180 days per plan year of in-network treatment your own physician, psychologist or psychiatrist finds medically necessary, and cannot run concurrent or retrospective medical-necessity review for the first 28 days of an in-network inpatient stay. Self-funded employer plans, Medicare and Medicaid are not covered by that rule, so verify with the plan. NJ FamilyCare covers the substance use continuum, from withdrawal management through outpatient care, with the level of care set by ASAM criteria and, for some levels, prior authorization. Our insurance guides go plan by plan.

ReachNJ, the state’s treatment referral line, answers at 1-844-732-2465, and the IME Addictions Access Center at 1-844-276-2777 screens NJ FamilyCare and uninsured residents and refers them to treatment. Both are independent of us. Periscope Behavioral Health, which publishes this site, is opening a medical detox in Hammonton, Atlantic County, expected Summer 2027. Until then, Periscope Behavioral Health, our publisher’s admissions line, at (888) 313-3583 can talk through options in New Jersey and Florida, including facilities Periscope operates. What a plan covers depends on the plan and the facility’s network status.
