GG4 vs. OG Kush: Two Chemdawg Descendants, Same Terpenes in Opposite Order

GG4 and OG Kush are two of the most recognized strains on Vermont dispensary menus. Both trace to Chemdawg, both run heavy and earthy, and both get reached for at the end of the day. But they're not the same strain, and the difference matters more than the similarity.

The key: both carry the exact same three terpenes — Caryophyllene, Limonene, and Myrcene — in opposite dominance order. GG4 is Caryophyllene-first. OG Kush is Myrcene-first. That inversion is where the strains diverge: different onset speeds, different body-lock character, different potency ceilings, different aroma signatures — all from the same three terpenes rearranged.

TL;DR

GG4 — Caryophyllene → Limonene → Myrcene. 23–28% THC. Chem Sister × Sour Dubb × Chocolate Diesel. Fast onset, heavy couch-lock, chemical-diesel aroma. Evening-only; experienced consumers. The heavier commitment of the two.

OG Kush — Myrcene → Limonene → Caryophyllene. 19–26% THC. Chemdawg × Hindu Kush × Lemon Thai. Progressive body settling, hunger-forward, pine-lemon-fuel aroma. Afternoon to evening; broader use window; more forgiving for moderate-tolerance consumers.

COA fingerprint: Caryophyllene leading the terpene panel = GG4 profile (plus the higher potency). Myrcene leading = OG Kush profile.

The shared terpene architecture

Chemdawg's signature terpene trio — Caryophyllene, Myrcene, Limonene — passed to both descendants. It's the same set of terpenes that also defines Sour Diesel, GSC, and most of the major Chem-family strains that came out of the early 1990s Northeast underground.

Limonene stays fixed in position two in both strains — its mood-elevation contribution is consistent across the Chemdawg family. The inversion is between Caryophyllene and Myrcene in positions one and three.

Why the dominance order matters

Terpenes don't exist in isolation. The dominant terpene — the one the plant produces most of — shapes the character of the high more than the presence of any single terpene in trace amounts.

Caryophyllene-first (GG4): Caryophyllene is the only terpene with documented cannabinoid receptor activity — it binds to CB2 receptors, which are concentrated in the peripheral nervous system and immune tissue. A Caryophyllene-dominant strain hits the body-tension component faster and harder. In GG4, this translates to a fast onset where the body component arrives earlier and settles deeper. The Myrcene in position three extends the sedation without softening the initial hit.

Myrcene-first (OG Kush): Myrcene is associated with earthy-herbal character and the progressive body component — the classic "couch-lock" mechanism in traditional Kush landraces runs on high Myrcene expression. But a Myrcene-first onset is also slower and more gradual than a Caryophyllene-first one. OG Kush builds. The body settles progressively over the first 45–90 minutes rather than arriving in a single heavy wave. This makes the experience more manageable for most consumers — you can feel the progression and calibrate before it's too late to adjust.

Effect arc comparison

GG4:

• Minutes 5–20: Euphoric, elevated headspace. The Chem Sister parentage contributes a cerebral clarity early — you feel it behind the eyes first, with distinct mood lift. This is the most functional phase.
• Minutes 30–60: Caryophyllene-driven body lock sets in. Muscle tension releases completely. Limbs feel heavy. The mental component becomes spacious and less structured, the physical component dominant.
• Hour 1.5+: Full couch-lock for most consumers. Appetite kicks in strongly. The arc tends naturally toward sleep within two to three hours at normal doses.

OG Kush:

• Minutes 10–25: Mild cerebral lift and mood elevation — quieter and less pronounced than GG4's opening. The Limonene component is there, but it's not leading.
• Minutes 30–60: Myrcene-driven body settling begins. Warmth. Physical relaxation. The classic Kush hunger arrives in this window — OG Kush is more reliably hunger-inducing earlier in the high than GG4.
• Hour 1.5+: Progressive body heaviness increases. Not a hard lock in most consumers, but sustained relaxation with limited motivation to move. Sleep arrives naturally for many at two to three hours.

The practical difference: GG4 takes you to a deeper physical place faster. OG Kush gets you to a similar place, but more gently and over a longer ramp. If you've ever consumed OG Kush and thought it wasn't doing much before suddenly feeling very stoned, that's the Myrcene-first profile doing exactly what it's supposed to.

Aroma comparison

Both strains are pungent. Neither is the sweet-dessert territory of Gelato or the tropical-citrus territory of Mimosa. They share a common Chemdawg-family earthy-fuel foundation — but they've diverged from it in different directions.

GG4: Chemical-diesel-earth. The Chem Sister parent contributes a sharp, acrid, funky edge — something between burning rubber and gas station. Sour Dubb adds a sour diesel lift. Chocolate Diesel contributes a grounding earthiness with a faint coffee-dark note that's most apparent in the aftertaste. If you've ever smelled a bag and immediately thought "Chem" — heavy, industrial, chemical — that's GG4. It's not subtle. It fills a room.

OG Kush: Pine-lemon-fuel. The Limonene shift to position two is audible in the aroma: the characteristic OG Kush smell has a distinctive pine-and-lemon brightness layered over a Chemdawg-family fuel base. The Hindu Kush parent contributes an Afghani earthiness and a slightly skunky depth that rounds out the chemical edge. If you've smelled something and thought "that smells like the classic West Coast thing" — the pine-lemon-fuel combination — that's OG Kush. It's complex in a way that GG4 isn't.

The Chemdawg connection

Both strains descend from Chemdawg, the foundational 1991 strain grown from seeds found by the grower known as Chemdog in a bag of "Dog Bud" acquired at a Grateful Dead concert at Deer Creek Amphitheater in Noblesville, Indiana. Chemdawg's terpene profile — Caryophyllene → Myrcene → Limonene — is what both GG4 and OG Kush inherited and rearranged.

GG4's lineage through Chem Sister is the more direct path. Chem Sister is itself a Chemdawg phenotype — a sister plant to Chemdawg D, selected from the same 1991 seeds. When breeders Joesy Whales and Lone Watty crossed Chem Sister with Sour Dubb and Chocolate Diesel (an accidental cross caused by a hermaphroditic plant), the resulting GG4 retained Caryophyllene in position one — the same lead terpene as its ancestor Chemdawg. GG4 is, in terpene architecture, the most true-to-Chemdawg of the major Chemdawg descendants.

OG Kush's lineage is more hybrid. The cross of Chemdawg with Hindu Kush and Lemon Thai introduced a landrace Myrcene base from the Hindu Kush parent. That Myrcene influence was strong enough to overtake Caryophyllene in the dominance order — flipping the architecture to Myrcene-first. Limonene then rose to second position, producing the distinctive pine-lemon quality that defines OG Kush's aroma. The Caryophyllene didn't disappear; it just moved to third. It's still there on the COA — it's just no longer driving the onset.

Sour Diesel — the other major Chemdawg descendant — followed GG4's path rather than OG Kush's: it also runs Caryophyllene-first, making it more true-to-type in terpene architecture while taking the genetic expression in a sativa direction rather than GG4's heavy-indica direction.

When to choose GG4

• Full end-of-day decompression. You have nowhere to be for the rest of the evening. The couch-lock is the point, not a side effect. GG4 delivers reliably.
• Maximum physical relief. The Caryophyllene-first profile and high THC ceiling make GG4 one of the stronger body-effect options in Vermont's dispensary system.
• Pre-sleep (timed). Consumed 60–90 minutes before your intended sleep window, GG4 moves toward rest naturally. Don't time it too early — the high is too active in the first hour to be immediately restful.
• You've worked up to it. If OG Kush at 22–24% is already in your wheelhouse, GG4 is a reasonable step up. If you're still finding your footing with high-THC cannabis, start there instead.

When to choose OG Kush

• Earlier evening use (5–7pm). OG Kush's slower, more progressive onset fits an earlier evening window better than GG4. You can feel the build without committing immediately to full body lock.
• Dinner or before-meal appetite opening. The Myrcene-first profile makes OG Kush one of the more reliably hunger-forward strains — it tends to produce hunger earlier in the high, which GG4 also does but later.
• Classic West Coast experience. If you want the foundational pine-lemon-fuel aroma and the progressive Kush settle that defined a generation of California cannabis, OG Kush is the source. GG4 is Chem-family, not Kush-family.
• More versatile for social settings. The first 30–45 minutes of OG Kush's effect arc are more functional than GG4's. At low to moderate doses, it's possible to remain conversational and engaged. GG4 is harder to keep social.
• Moderate-tolerance consumers. The 19–26% THC ceiling and slower onset give you more room to find a comfortable dose. OG Kush is still a potent strain — not appropriate for day one — but it's more forgiving than GG4 at the same dose.

Reading the COA at a Vermont dispensary

Both GG4 and OG Kush list Caryophyllene, Limonene, and Myrcene on the terpene panel. The dominant terpene tells you which profile you're buying:

• Caryophyllene as lead terpene: GG4 architecture. Expect faster onset, heavier body lock, chemical-diesel aroma. Also cross-check the THC — genuine GG4-profile expression usually comes with the higher potency range.
• Myrcene as lead terpene: OG Kush architecture. Expect slower, more progressive settling, stronger hunger earlier in the high, the pine-lemon-fuel aroma signature.

If a batch labeled "GG4" has Myrcene as its dominant terpene, or if a batch labeled "OG Kush" leads with Caryophyllene, the phenotype expression is off — either the cultivar or the grow run diverged from the canonical profile. This happens; ask your budtender about the batch's lab data before choosing based on the name alone.

Vermont dispensary availability

Both strains are among the most reliably available at Vermont's licensed dispensaries. GG4 is widely carried in flower and appears frequently in concentrate and rosin form, given its exceptional resin production. OG Kush is a year-round floor staple — one of the first strains any new Vermont dispensary stocks and one of the last to go on sale.

Float On Dispensary (136½ Church St, Burlington), Upstate Elevator Supply Co. (699 Pine St, Burlington), and The High Bar (159 Pearl St, Essex Junction) carry both strains in regular rotation. Vermont cannabis law (S.278, eff. July 1, 2026): adults 21+ may purchase and possess up to 2 oz flower / 10 g concentrate.
