🌿 What Is Gorilla Glue? A Quick Overview

Originally bred by crossing Chem’s Sister, Sour Dubb, and Chocolate Diesel, Gorilla Glue earned its name because of how sticky its resin is — it “glues” trimming scissors shut. Over time, breeders isolated different phenotypes: GG1, GG4, and GG5. While they all share the same lineage, their effects, THC content, and intensity vary considerably.

Because of its reputation, Gorilla Glue has become a go-to for both recreational and medicinal users alike.

💥 Comparison Chart: Gorilla Glue Strains by Potency

Strain	THC Content	Type	Key Effects
GG1	18–22%	Balanced hybrid	Uplifting, smooth high
GG4	24–30%	Indica-leaning	Full-body buzz, couchlock
GG5	27–32%	Indica-dominant	Heavy sedation, pain relief

✅ Top Pick: GG5 (New Glue) – the strongest Gorilla Glue strain, based on THC and user reviews.

🧬 GG1 – Smooth and Balanced

Although GG1 isn’t as widely available as GG4, it remains a solid choice for those who prefer balance over brute strength. It delivers a gentle cerebral lift followed by relaxing body effects. Because of its lower THC range (18–22%), GG1 is suitable for daytime use and new users.

Moreover, its clear-headed high makes it ideal for focus and creativity. If you’re looking for something mellow but still effective, GG1 won’t disappoint.

🔹 Best for: Socialising, creative focus, light relief
🔹 Avoid if: You want intense sedation

🧠 GG4 – The Classic “Original Glue”

Gorilla Glue #4 is the strain that put the Glue family on the map. Thanks to its balanced hybrid genetics, it offers a powerful yet versatile high. Typically testing between 24–30% THC, GG4 delivers a euphoric onset that quickly transitions into deep body relaxation.

Furthermore, GG4 is known for its strong diesel aroma with earthy, slightly sour notes. As a result, it’s beloved by both recreational users and those seeking stress or pain relief.

🔹 Best for: Evening use, stress, pain, winding down
🔹 Avoid if: You need to stay mentally sharp

🛌 GG5 – The Most Potent Gorilla Glue Strain (aka New Glue)

If you’re looking for sheer power, GG5 (sometimes called New Glue) is the clear winner. Engineered to boost THC content and dial up the indica traits, GG5 regularly tests at 27–32% THC. In some cases, it can even exceed that range with proper cultivation.

Right from the first inhale, GG5 brings on a wave of sedation. Your limbs may feel heavy, your mind will slow down, and sleep is never far away. Additionally, its strong body effects make it a favourite for managing chronic pain and insomnia.

🔹 Best for: Hardcore users, sleep, pain relief
🔹 Avoid if: You’re a beginner or need to stay active

🔍 Which One Should You Try First?

Here’s a quick cheat sheet to help you decide:

Goal	Recommended Strain
All-day focus with light effects	GG1
Balanced hybrid with a punch	GG4
Maximum sedation and potency	GG5

While each strain has its place, GG5 is the strongest Gorilla Glue strain overall. Nevertheless, GG4 offers a perfect balance of flavour, strength, and versatility which explains why it’s still the most popular.

🧠 Final Thoughts: It’s More Than Just THC

Although THC is a big factor in strength, it’s not the whole story. Terpenes, tolerance, and your personal endocannabinoid system all play a role. In many cases, a strain with slightly lower THC but rich terpene content (like myrcene or limonene) may feel stronger to you.

Still, if you want raw, knockout power, GG5 (New Glue) is your best bet in 2025.
