MAC Stomper Strain

MAC Stomper Strain: Cookie-Dough Grape With a Heavy Second Half

The MAC Stomper strain is what happens when Capulator's MAC cut meets Grape Stomper OG — a resin-caked, indica-leaning hybrid that smells like vanilla shortbread dusted with grape peel, then quietly pins you to the couch. Leafly files it as a hybrid with myrcene on top; AllBud calls it roughly 70% indica at 16–25% THC. For that dessert-and-dark-fruit register in federally compliant hemp, start with our THCA flower collection.

It's a hash-maker's strain more than a numbers strain. Grant Pharms' Colorado batches list 20.7% and 21.46% THC on Weedmaps — respectable, not record-breaking. Nobody who smokes it talks about the percentage anyway; they talk about the trichome load and the way the grape arrives after the cookie, not with it.

MAC Stomper Strain Genetics & Lineage

The parents are the one thing nearly everyone agrees on. Leafly, AllBud and Theory Wellness all land on the same cross — MAC on one side, Grape Stomper on the other. They split on the fine print.

• Parents: MAC × Grape Stomper OG (Leafly); AllBud drops the OG; Theory Wellness is most specific at MAC 1 × Grape Stomper OG
• Breeder: Theory Wellness credits Capulator, who stabilized Miracle Alien Cookies; Leafly lists the breeder as unknown. Joint Commerce notes Capulator has never publicly confirmed the Grape Stomper donor — treat that half as reported, not documented
• THC: 16–25% (AllBud), with Grant Pharms' Colorado retail batches listed at 20.7% and 21.46%
• Minor cannabinoids: CBD 0% on Leafly and Grant Pharms' listings; Joint Commerce says under 0.5% with trace CBG and CBC
• Offspring: Fire And Ice and Elote (Leafly); Apple Stomper from High Five Genetics (Joint Commerce); a Mac Stomper F2 by Sunken Treasure Seeds on SeedFinder, which produced Lime Jelly
• Awards: none we could verify — it spread on cultivator word-of-mouth, not cup wins

The MAC side: the cut that made a decade

MAC — Miracle Alien Cookies, also sold as MAC 1 — is one of the most-cloned cuts of the last decade. In a Leaf Magazines profile marking ten years of the strain, Capulator describes Starfighter × Colombian seeds that got run through a washing machine by accident; every survivor died except number 15, and crossing that plant with Alien Cookies F2 produced MAC. That cookie-dough-and-citrus top note is its fingerprint, and it's the first thing you taste here.

The Grape Stomper side: where the dark fruit comes from

Grape Stomper is a Gage Green Genetics release. SeedFinder lists it as Purple Elephant × Chemdog Sour Diesel — so the grape traces through Chemdawg and Sour Diesel, which is why a dessert strain still has a sour edge on the exhale. SeedFinder also notes it circulated as Sour Grapes, with 51 direct descendants. Grape Stomper OG is the OG-crossed selection of that line.

MAC Stomper Terpene Profile

We found no published terpene panel for MAC Stomper with real percentages attached — worth saying out loud rather than inventing numbers. What exists is two sources naming an order and disagreeing about first place.

Leafly's data panel puts myrcene most abundant, then caryophyllene, then linalool. Joint Commerce's grower guide leads with beta-caryophyllene, limonene and myrcene behind, and pegs total terpenes at 1.5–3.5% by weight — above 4% on the best craft runs. Both describe the same result: sweet grape and citrus up front, pepper underneath, herbal weight at the end.

• Caryophyllene — the pepper-clove note that keeps a grape-candy strain from tasting like soda.
• Myrcene — the usual suspect behind that heavy-limbed second half.
• Limonene — the sour citrus lift, and why the first twenty minutes feel brighter than "70% indica" suggests.
• Humulene — a secondary per Joint Commerce; hoppy and dry, under the pepper.

Appearance

AllBud describes dense, rounded buds in olive green with deep purple undertones, thin orange hairs and tiny purple-tinted white trichomes. Joint Commerce is more specific: tight node stacking, bulbous trichomes with a glassy sheen, pistils from tangerine to deep copper over lime-to-forest-green calyxes.

Those violet streaks aren't guaranteed — per the same source they appear mostly in cooler late-flower rooms around 65–68°F, so a purple bag and a plain green one can be the same cut grown two ways. The resin is non-negotiable: if a jar doesn't leave your fingers tacky, something went wrong in the dry.

Aroma and Flavor

The nose is sweeter and more floral than the smoke. AllBud describes a rich, wine-like grape with a hint of earth — tagged berry, citrus, earthy, flowery, sour, spicy. Joint Commerce's dry-pull notes go further into dessert: vanilla shortbread or powdered sugar, grape peel, orange zest, then brighter citrus and pine once you grind it.

Flavor arrives in sequence: cookie and sweet grape first, sour lemon-lime through the middle, then a peppery finish that doesn't match the smell at all. Leafly's top tags are apple, grape and berry; AllBud reads it as fruity berries and spicy grape with a tingly sour citrus end. Vaping at 350–375°F keeps the citrus forward; past 390°F you get spice and caramel.

Recreational Effects

MAC Stomper opens friendlier than it finishes. Leafly readers report euphoric, relaxed and happy; Theory Wellness describes an initial boost toward positive, creative thinking before cozy, full-bodied relaxation takes over. Phat Panda's listing is blunter: giggles and a better mood, then deep physical relaxation and a strong appetite.

• Euphoric — the opening act, short and genuinely cheerful
• Relaxed — the main event, heavier the longer you sit still
• Happy — mood lift that outlasts the head change
• Sleepy — AllBud's tag, and why this is an evening strain
• Hungry — AllBud and Weedmaps reviewers flag the appetite specifically
• Stony — AllBud's word; at higher doses expect couchlock

How the high unfolds: onset, peak and duration

• 0–3 minutes: fast inhaled onset, per Joint Commerce. Pressure behind the eyes, a little giddy.
• 5–15 minutes: the cerebral part — brighter and more talkative than the indica label suggests.
• 20–30 minutes: peak. Body weight shows up, head quiets down. Decide now whether you're going anywhere.
• 45–90 minutes: deep relaxation, strong appetite, low ambition. Pleasant and immovable.
• 2–3 hours: total duration inhaled, per Joint Commerce. Most people slide into sleep off the tail.

How Strong Is MAC Stomper?

Every published number we found: 20.7% THC / 0% CBD on Grant Pharms' Smalls and 21.46% / 0% on their #7 and #9 cuts, both via Weedmaps · 16–25% (AllBud) · a 15% header on Leafly that the same page contradicts with "unknown% THC" while calling it "higher THC than average" · above 20% on most batches, mid-20s ceiling, 22–30% total cannabinoids (Joint Commerce) · no figure at all on SeedFinder, Theory Wellness or Phat Panda.

Call it low-to-mid twenties and ignore the 15% — Leafly's own copy disowns it. The two Colorado batches just over 21% are the most trustworthy figures here, because they're retail lab results rather than crowd-sourced averages.

One thing trips people up: a THCA flower COA and a dispensary THC COA don't measure the same way. Raw flower is almost entirely THCA, which only becomes delta-9 THC under heat. Some labs report total potential THC after conversion, some report THCA as-is, and identical flower looks wildly different either way. Our guide to reading a THCA COA shows which line matters; what counts as a good THCA percentage adds context.

MAC Stomper vs Similar Strains

• vs MAC: the parent, and the more balanced one. MAC keeps you functional; this bolts a sedative to the cookie-citrus top note.
• vs MAC 1: the selected, famously finicky version — brighter, more cerebral, harder to find grown properly.
• vs Banana MAC: the other well-known MAC cross — tropical and sweet where this goes dark and winey.
• vs Grape Gas: closest on the grape-plus-fuel axis, minus the cookie-dough layer.
• vs Purple Punch: both grapey and sedating — Purple Punch is candy-sweet and simpler.
• vs Ice Cream Cake: similar body weight, creamy vanilla instead of fruit-and-pepper.

Who MAC Stomper Is (and Isn't) For

It's an evening strain for people with some tolerance. Leafly says plainly that it suits experienced consumers, and reviewers on Leafly and AllBud describe a racing mind when they went in too hard. Flavor chasers will like it, and so will anyone who presses hash.

It isn't a workday strain and it isn't a first strain. To stay functional, go toward the MAC side of the family or a sativa-leaning option. And if you're anxiety-prone: anxiety is both the most common reason Leafly readers reach for this one and a recurring complaint in its reviews, which usually means dose is doing the deciding.

How to Use MAC Stomper THCA Flower — and How Much

Raw THCA isn't intoxicating. Heat converts it to delta-9 THC — the whole mechanism behind why THCA flower gets you high smoked and does nothing eaten cold. A lighter, a dry herb vape or an oven all do the job.

• Joint or pre-roll: two or three pulls, then wait — Joint Commerce advises 10–15 minutes between inhalations with this one.
• Dry herb vape at 350–375°F: the flavor route. You lose the toasty finish but gain the grape.
• Glass: small bowls. The fourth hit is the one you regret.
• Hash and rosin: where this cut shines. If you press, it's worth the trichomes.
• Edibles: decarb around 240°F for 30–40 minutes before infusing, or the THCA never converts.

Dosing, honestly: one or two pulls if you're new, three or four if you're not, then stop for a quarter hour. The 20-minute mark is when the body weight announces itself, and it's easier to add than subtract. Eat first — the appetite is not subtle.

Medicinal Benefits

These are consumer-reported uses, not clinical findings. Leafly's reader data puts anxiety at 32–33% of reports, depression at 15–16% and pain at 15–16%. AllBud lists chronic pain, depression, insomnia and stress; individual reviewers mention bipolar disorder, spinal cord injury and loss of appetite.

The pattern fits the profile — an indica-dominant, myrcene-and-caryophyllene cut with a strong appetite effect is what people reach for at night. None of this is medical advice and nothing here treats any condition. Talk to your doctor before using hemp for a medical reason, especially alongside prescriptions.

Side Effects and Cautions

Leafly readers name paranoia, dizziness and dry eyes as the top negatives — paranoia first, which is unusual and worth respecting on a strain this heavy. Dry mouth runs through the reviews. One AllBud reviewer reported heightened anxiety; another just got very hungry.

Practical version: water nearby, no stacked doses in the first half hour, skip the alcohol — Joint Commerce flags couchlock specifically when higher doses meet drinking. Don't drive. If you're prone to THC anxiety, a two-pull ceiling on the first run is cheap insurance.

Is MAC Stomper Top Shelf? How to Judge a Good Bag

MAC-family genetics reward careful growers and punish rushed ones, so the jar tells you more than the name does.

• Resin, first and always. Bulbous trichomes with a glassy sheen are the signature. A dry, dusty bag is a failed one.
• Stickiness. It should resist the grinder slightly.
• Nose through the bag. Grape and vanilla sugar should reach you before you open it. Joint Commerce notes hot or rushed drying can cut terpene totals by 30% or more, and that loss reads as flat, generic sweetness.
• Bud structure. Dense and tightly stacked, olive to forest green, copper-orange pistils. Purple is a bonus, not a grade.
• The COA, not the number. Check the test date and the terpene line. A 19% jar with 3% terps beats a 25% jar with 1% every time.

Growing MAC Stomper

Grow data is thin. SeedFinder's only MAC Stomper entry is the F2 from Sunken Treasure Seeds: 9 weeks of flowering — about 63 days — indoor or outdoor, never released as feminized seed, no known distinct phenotypes. That's the one hard number we found, and it's the F2, not the original.

Joint Commerce adds framing without a flowering figure: predictable and indoor-ready, topped at the fifth or sixth node and trellised, with 14–21 days of veg from a rooted clone giving 24–30 inch plants ready to flip. SeedFinder puts Grape Stomper itself at about 72 days. No credible flower yield figure exists anywhere we looked — only that hash yields run above average for a dessert hybrid.

Is MAC Stomper THCA Flower Legal?

Hemp-derived THCA flower sits in the lane the 2018 Farm Bill opened. Hemp is defined by delta-9 THC content — not more than 0.3% dry weight — and raw, un-decarbed compliant THCA flower meets that threshold. The USDA's hemp program pages are the source.

State law is what varies. Several states have rules targeting high-THCA hemp, and they change — check yours. Diesel Hemp does not ship to Colorado residents.

For most people the drug-test point matters more: compliant hemp flower still produces THC metabolites once smoked, and a urine screen can't tell hemp from dispensary THC. If you're tested for work, don't smoke it — our page on THCA and drug tests covers why.

Frequently Asked Questions

Is MAC Stomper indica or sativa?

Indica-dominant hybrid. AllBud puts it near 70/30 indica, SeedFinder calls the F2 "mostly indica," Phat Panda files it as straight indica. Leafly just says hybrid.

What are the MAC Stomper strain's effects?

A short, talkative euphoric lift, then a heavy body stone with a strong appetite. Leafly readers report euphoric, relaxed and happy; AllBud adds sleepy.

What is MAC Stomper's lineage?

MAC × Grape Stomper OG. Theory Wellness specifies MAC 1; AllBud drops the OG. Grape Stomper itself is Purple Elephant × Chemdog Sour Diesel per SeedFinder.

Who bred the MAC Stomper strain?

Theory Wellness credits Capulator, the breeder behind MAC. Leafly lists the breeder as unknown, and Joint Commerce notes Capulator never confirmed the Grape Stomper donor — widely reported, not documented.

What is MAC Stomper's THC level?

Around 20–25%. Grant Pharms' Colorado batches list 20.7% and 21.46% THC at 0% CBD; AllBud gives 16–25%. Ignore Leafly's 15% header — the page's own text says "unknown% THC."

What terpenes are in MAC Stomper?

No published panel with percentages turned up. Leafly ranks myrcene, caryophyllene, linalool; Joint Commerce puts beta-caryophyllene first with limonene and myrcene behind, plus pinene and humulene as secondaries.

What does MAC Stomper taste like?

Sweet grape and cookie dough first, sour lemon-citrus through the middle, black pepper on the finish. Leafly's top tags are apple, grape and berry.

What is MAC Stomper's flowering time?

About 9 weeks — roughly 63 days — for the Mac Stomper F2 from Sunken Treasure Seeds, per SeedFinder. No source we read publishes one for the original clone.

Can you buy MAC Stomper seeds?

Not easily, and not the original. SeedFinder catalogs the Sunken Treasure Seeds F2 and notes it was never available as feminized seed. The original is clone-only in practice.

What is the MAC Stomper NEZ version?

NEZ is an Illinois craft cultivator, and a Leafly reviewer credited their MAC Stomper specifically. Same genetics, grown by a brand with a reputation — not a separate strain. Same reason people search Phat Panda's version in Washington.

Is MAC Stomper good for sleep?

It's used that way. AllBud lists insomnia among its tags and calls the strain sleepy; Theory Wellness describes cozy, full-bodied relaxation. Consumer-reported, not clinical, and not medical advice.

Is MAC Stomper the same as MAC or MAC 1?

No. MAC and MAC 1 are the parent cut; MAC Stomper is that crossed with Grape Stomper OG — heavier, grapier and more sedating than either parent.

Does Diesel Hemp sell MAC Stomper THCA flower?

Not right now. The closest cut in stock is Super Boof THCA Flower — dark fruit over a cookie base, same late-arriving body weight. The full lineup is in the THCA flower collection.
