Gorilla Glue #4 (GG4)
High-THC resin-heavy hybrid now legally marketed as Original Glue.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
GG4 is a real, well-documented strain with genuine competition wins and distinctive resin production. But most cuts sold today are not the original GG Strains clone—they're seed-grows or different cuts entirely. Lab THC readings are reliable; specific medical claims tied to this strain are not. It's a high-THC option for experienced users, not beginners.
Overview
Gorilla Glue #4—now legally marketed as Original Glue—is a high-THC hybrid bred in the United States by Joesy Whales and Lone Watie, who founded GG Strains LLC. The strain became widely recognized after sweeping the High Times Cannabis Cup in Los Angeles and Michigan in 2014, and again at the World Cannabis Cup in Jamaica in 2015.
The name reflects the strain's defining trait: extreme resin production dense enough to gum up trimming scissors and tools. Buds are typically chunky and pale green, frosted with cloudy trichomes. The aroma combines diesel, sour chocolate, coffee, and pine notes.
In 2017, the Gorilla Glue Company (the adhesive manufacturer) sued GG Strains for trademark infringement [1]. The case settled, and GG Strains agreed to retire the 'Gorilla Glue' name by 2020. The cultivar is now officially called Original Glue, and the company rebranded as GG Strains [1].
Lineage and authenticity
GG Strains' official lineage for GG4 is Chem's Sister × Sour Dubb × Chocolate Diesel [2]. According to the breeders, GG4 emerged from a chance pollination: a Chocolate Diesel hermaphrodite pollinated a Sour Dubb plant, and phenotype #4 from the resulting seeds became the mother cut [2].
Important caveats:
- Clone-only authenticity: The original GG4 is clone-only. Seeds sold as 'GG4' or 'Original Glue' are selfed (S1) or crossed plants, not the original cut. Phenotype variation is significant.
- Lineage is not DNA-verified: Cannabis cultivar pedigrees are typically breeder claims, not laboratory-confirmed records. Genetic tools have revealed that many named strains on the market don't match their stated parentage [3] Disputed.
- What you buy may not be the original: Most 'GG4' found in legal dispensaries is likely a seed-grown phenotype, a different cut, or in some cases a different strain relabeled entirely. Genetic verification in the retail market is rare [3].
Chemistry: cannabinoids and terpenes
Cannabinoids
GG4 is a THC-dominant Type I cultivar with negligible CBD expression. Licensed testing labs consistently report total THC in the 24–28% range, occasionally higher, with CBD typically below 0.1% Strong evidence[4]. There is minimal CBG, THCV, or other minor cannabinoid content in the standard cut.
Terpenes
Published lab data and aggregated terpene profiles indicate β-caryophyllene as the most abundant terpene, followed by myrcene, limonene, and humulene; some phenotypes express notable α-pinene [4][5] Weak / limited. Total terpene content is typically moderate-to-high (1.5–2.5% by mass), which correlates with the strain's distinctive, loud aroma.
A note on terpene mythology: The widely repeated claim that myrcene above 0.5% makes a strain 'indica' or 'couch-locking' is not supported by controlled human research No data. See The Myrcene 0.5% Threshold for details. Terpene profiles correlate with aroma and flavor, not reliably with subjective effect categories.
Reported effects
There are no strain-specific clinical trials of GG4. What follows is aggregated user report and anecdote, not clinical evidence Anecdote.
Commonly reported:
- Fast, heavy onset; strong body relaxation
- Early euphoria and talkativeness; later sedation
- Significant appetite stimulation
- Dry mouth and red eyes (typical for high-THC flower)
Likely overstated or unsupported:
- Specific medical claims (pain relief, insomnia management, PTSD treatment)—observational and survey data show high-THC cannabis can correlate with self-reported short-term pain reduction and sleep improvement in some users, but no trial evidence is GG4-specific [6] Weak / limited.
- 'Couch-lock' as a guaranteed effect—depends heavily on dose, individual tolerance, and neurochemistry, not strain name alone.
- Relief from anxiety—while some users report anxiety relief at low doses, high-THC cannabis (including GG4) is more commonly associated with anxiety and paranoia, especially in high-dose contexts or for users with sensitivity [6] Strong evidence.
GG4 is not beginner-friendly due to its THC content and rapid onset. Users new to cannabis or with low tolerance should start with lower-THC options.
Growing Gorilla Glue #4
GG4 has a reputation among growers as vigorous, tolerant, and high-yielding, though it requires hands-on management.
Flowering and harvest
- Indoors: 8–9 weeks
- Outdoors (northern hemisphere): early-to-mid October
Structure and support
- Tall, stretchy in early flower (often doubles in height); topping or mainlining is common
- Colas are dense and heavy; stake or trellis early to prevent branch breakage
Feeding
- Tolerates moderate-to-heavy feeding but is prone to nutrient burn if pushed too hard late in flower
- Monitor leaf color and adjust accordingly
Environmental conditions
- Prefers a drier flower environment; dense buds are susceptible to botrytis (bud rot) in humid conditions (above 50% RH in late flower)
- Good air circulation is essential
Hermaphrodite risk
- The original line traces back to a hermaphrodite Chocolate Diesel parent. Stress-induced pistillate flowers ('nanners') are a documented risk, particularly in S1 seed plants
- Avoid severe heat or light stress during flower
Seed vs. clone Authentic GG4 is clone-only. Seeds sold as 'GG4' will produce variable phenotypes; if you want the original cut, source from a verified grower with the authentic clone.
Marketing vs. reality
What's real:
- GG4 is a genuinely distinctive, high-THC, resin-heavy cultivar with documented competition wins and a traceable breeder origin [1].
- The aroma profile and trichome density are consistent across legitimate cuts—not marketing hype.
- Lab-tested THC and terpene readings from licensed facilities are reliable Strong evidence.
What's marketing or folklore:
- 'GG4 on a dispensary shelf is almost certainly not the original clone.' It is likely a seed-grown phenotype, a different cut, or a different strain relabeled. Genetic verification in the legal retail market is rare [3].
- Specific medical-effect claims tied to GG4 (e.g., 'cures insomnia' or 'best for PTSD') are not based on strain-specific evidence No data.
- 'Indica-leaning hybrid' as a predictor of effect is folklore. The Indica/Sativa Myth has been repeatedly shown not to predict chemical profile or user experience reliably [7] Strong evidence.
- 'Myrcene makes it relaxing' is unsupported by controlled research No data.
If you see GG4 marketed as a 'pure indica,' 'guaranteed couch-lock,' or with hyper-specific medical claims, that is the seller's marketing, not science.
Frequently asked questions
Is GG4 an indica or sativa?
GG4 is classified as a hybrid, typically described as 'sativa-leaning' or 'balanced.' However, the indica/sativa distinction doesn't reliably predict effects or chemistry. See The Indica/Sativa Myth for why this classification is more historical than meaningful.
What is the THC level?
Licensed labs typically report 24–28% total THC, with CBD below 0.1%. These numbers vary by grower, harvest time, and testing lab, but are reasonably consistent Strong evidence.
How long does it flower?
Indoors: 8–9 weeks. Outdoors in the northern hemisphere: early-to-mid October. The exact timing depends on photoperiod and environmental conditions.
Who originally bred GG4?
Joesy Whales and Lone Watie, founders of GG Strains LLC. The strain is now legally marketed as Original Glue following a 2017 trademark settlement with the Gorilla Glue Company [1].
