Indica-dominant hybrid

MAC Stomper Strain

MAC Stomper combines sweet grape, orange-like citrus and an earthy undertone with a happy, euphoric and relaxed reputation. Consumer and producer descriptions bring a mental lift together with a settled body feeling. The brighter mood and physical calm are complementary parts of its character, rather than a promise that it will feel either stimulating or sleepy.

Capulator's cross pairs MAC 1 with Grape Stomper OG. Its richer grape sweetness and sharper orange edge give the fruit profile definition. Limonene leads the individually reported terpenes in the flower sample featured below, providing a measured comparison with the citrus descriptions while leaving room for a different balance in other batches.

What it is known for

MAC Stomper effects and experience

  • Euphoric
  • Relaxed
  • Happy

Euphoric, relaxed and happy are recurring consumer descriptions. Producer accounts describe a similar combination of mental brightness and a more comfortable, settled body feeling.

Those qualities can coexist: relaxed does not necessarily mean immediately sleepy, and a mental lift does not necessarily mean stimulation. Reports also include dizziness and paranoia, which matter alongside the more appealing descriptions. The name is a starting point for understanding the strain’s reputation, not a prediction of an individual response.

Aroma, flavor and appearance

  • Grape
  • Citrus
  • Orange
  • Earthy

MAC Stomper combines grape sweetness with a brighter citrus edge. Orange gives the fruit a fresher character, while earth adds depth beneath it. The contrast between richer grape and sharper citrus is more useful than a simple sweet-fruit label.

Limonene is the leading individually reported terpene in the flower sample below, giving a measured point of comparison with those citrus descriptions. Its concentration does not describe the whole aroma: the grape and earthy character also matter when comparing how actual flower smells and tastes.

Understanding this sample

What this terpene profile means

Limonene has a clear lead. This sample contains more than twice as much limonene as the next-largest reported terpene, caryophyllene. Alpha-pinene and linalool follow at lower concentrations.

Leading terpenes Reported concentration in flower

Open a terpene to explore its aroma and the research on effects.

Limonene0.75%Citrus

Citrus is a useful family reference; the d-limonene flavor reference describes orange and lemon notes. A flower’s fruit character also depends on compounds beyond limonene.

Could it change THC-related anxiety?

Early human research

A small controlled study found that added d-limonene reduced some anxiety-related effects of THC. This is an early finding under specific conditions, not evidence that limonene-rich flower is reliably calming or energizing.

Research context & sources

The study enrolled 20 adults; the strongest finding came from a higher-limonene condition completed by 12. It tested isolated vaporized compounds, not these flowers. This report names limonene without specifying its form.

Caryophyllene0.31%Form not specified

The report uses the general name “caryophyllene.” Beta-caryophyllene is associated with spice and wood, but this result does not explicitly identify that form.

Can we apply beta-caryophyllene research here?

Compound identity incomplete

The commonly discussed receptor research concerns beta-caryophyllene. We keep that distinction visible rather than assigning its findings to a lab result with an unspecified form.

Research context & sources

More precise identification from the laboratory would be needed before linking this measurement to research on a particular form. No predicted body effect is assigned.

Alpha-pinene0.14%Pine · cedarwood

Pine and cedarwood provide a familiar way to picture this compound’s sharp, woody character. The aroma reference is separate from claims about mental clarity.

Does it protect memory or improve clarity?

Human study: benefit not found

A controlled study in 19 adults did not find that added alpha-pinene prevented THC-related memory impairment or meaningfully changed the other acute effects measured. A pinene result should not be read as a promise of clearer thinking.

Research context & sources

The study tested isolated vaporized alpha-pinene with and without THC. Its result addresses the tested memory-protection claim; it does not prove that the compound has no possible biological effects.

Linalool0.12%Floral · lavender

Floral and lavender-like are useful reference points for this compound. They describe an aroma association, not a claim that the flower will smell exactly like lavender.

Could it contribute to relaxation?

Animal research

An inhalation study found reduced anxiety-like behavior in mice under some exposure conditions. This makes a calming role worth investigating, but does not show that the amount in this flower causes relaxation or sleepiness in people.

Research context & sources

Responses differed with exposure pattern and sex. The study also tested combinations with CBD; it did not test this flower or establish a human effect threshold.

0%1% of flower by mass

Bar length shows amount, not strength of aroma or effect. These measurements use dry flower weight. Other measured terpenes appear in the full table below.

Limonene: about 44% of the reported terpene total. This describes its share of the measured mixture, not its share of the experience.

How does that relate to the experience?

Relaxed, happy and euphoric are common descriptions of MAC Stomper. Its limonene lead does not automatically make this sample energizing, and the pinene result does not promise clearer thinking. The individual research notes explain which proposed effects have been tested.

Make sense of the percentages
Amount in the flower
Limonene is reported at 0.75%, equivalent to 7.5 milligrams per gram of dry flower. This describes what is in the flower, not the amount a person absorbs.
Share of the terpene total
Dividing the 0.75% limonene result by the 1.7% reported terpene total gives about 44%. Both use the same measurement basis. This is a share of this report’s total, not a complete inventory of every possible aroma compound.
Contribution to the experience
A larger chemical share does not establish a larger effect. The research summaries explain what has been studied; none provides an effect score for this flower.
Why the chart cannot describe the whole aroma

The aroma notes are familiar references for the compounds, not a tasting report for this sample. Other volatile compounds also shape a flower’s smell, and a small amount of a potent odorant can matter more than a larger amount of another compound.

Sensory research on cannabis flower and extracts supports keeping aroma descriptions separate from a ranking by concentration.

The story behind the strain

Genetics and history

Reported parentage · accounts or versions differ

MAC 1Grape Stomper OG

MAC Stomper is a Capulator hybrid described as MAC 1 × Grape Stomper OG. Its character centers on grape and citrus aromas with an earthy undertone, alongside reports of relaxation and a pleasant mental lift.

It is a separate strain from MAC or MAC 1. The added Grape Stomper OG parent is part of its published identity, so descriptions and lab results for the other MAC names should not simply be carried across.

Sources & notes

Producer-attributed pedigree

Both producers name MAC 1 × Grape Stomper OG and Capulator. The laboratory report supplies product identity only.

For growers

Growing MAC Stomper

Published characteristics for the named versions below. Flowering time excludes the earlier growth period; seed-to-harvest estimates cover the full cycle.

Capulator MAC Stomper (archived description)

Flowering time
7–9 weeks
Starting material
Regular seeds
Source [3]

The archived Capulator release is described as regular seed with a 7–9-week flowering period. Regular seed identifies a seed format that can produce male and female plants; it does not mean that every plant has identical traits.

A commercial flower producer may work with a particular selection from that broader line. That helps explain why a producer’s MAC Stomper can have a recognizable presentation without defining every seed-grown example.

The published material supports the named cross more clearly than a universal height or yield specification. For this guide, the release description stays separate from the Northeast Laboratories results in the cannabinoid and terpene section. Those measurements document one product received in July 2025 and reported in August, rather than the expected chemistry of future plants.

MAC Stomper questions

What are MAC Stomper’s parents?

VIBE and Theory Wellness describe it as MAC 1 × Grape Stomper OG and attribute the cross to Capulator.

Is MAC Stomper the same as MAC or MAC 1?

No. MAC Stomper is a separate cross with Grape Stomper OG in its published parentage. A shared MAC name does not make the products interchangeable.

What does MAC Stomper smell like?

Grape and bright citrus are recurring descriptions, with orange and earthy notes in producer accounts.

What was the THC level of the tested MAC Stomper sample?

The August 2025 Northeast Laboratories report recorded 20.94% total THC on a dry-weight basis. That figure describes its identified flower product, not every MAC Stomper batch.

Which terpene was highest in that sample?

Limonene was the largest individual terpene result at 0.75% dry weight. The report’s full panel is available below; another producer’s flower may differ.

Does MAC Stomper’s limonene level mean it is energizing?

No. Limonene leads this sample’s measured terpene profile, but that is not an energy score. A small human study investigated d-limonene and THC-related anxiety; it did not establish that limonene-rich flower is stimulating or reliably calming.
