If you have just opened your latest order and found the oil inside looks solid, cloudy, or separated, you are not alone. We receive dozens of messages about steroid oil crystallization winter every year when temperatures drop. It looks alarming, but we promise your gear is not ruined.
Understanding Steroid Oil Crystallization in Winter
Why does this happen? Steroid oil crystallization winter events occur because high-concentration products like NPP (Nandrolone Phenylpropionate), EQ (Boldenone Undecylenate), and Sustanon contain a high amount of hormone dissolved in the oil. When these vials sit in a freezing delivery truck or a cold porch for hours, the low temperature causes the hormone particles to “crash” or fall out of the solution.
This phenomenon is actually well-documented in pharmaceutical science. Research into injectable oil vehicles, such as this study on Virgin Coconut Oil Containing Injectable Vehicles, specifically notes that “the wax formation dispersed in this oil during storage at cool environment makes it not homogenous and opaque.” The study confirms that this is a “problematic behavior” of oil-based solutions exposed to cold—exactly what you are seeing in your vial.
It is the exact same science as honey crystallizing or olive oil solidifying in a cold fridge. The cold changes the physical state, but it does nothing to change the chemical potency or safety of the compound.
Does Steroid Oil Crystallization in Winter Ruin the Product?
Absolutely not. This is purely a cosmetic issue. The vial remains sterile, and the hormone is still active. Once you return the oil to room temperature (or slightly warmer), it will dissolve back into a perfect liquid ready for use.
This is a widely discussed topic within the community as well. For example, this discussion thread on EQ Crashed shows real-world experiences from users who encountered the same issue. In the thread, members share photos of their vials and confirm that gently heating the solution resolved the problem completely.

This is what steroid oil crystallization winter looks like. It’s just the hormone crashing from the cold.
How to Reverse Steroid Oil Crystallization in Winter
If you are dealing with steroid oil crystallization winter, do not panic and do not throw the vial away. Here is the simple, safe method to fix it:
- Heat Some Water: Boil water and let it cool slightly, or run your tap until it is hot (but not scalding). You want it warm enough to dissolve the crystals, but not boiling, as extreme heat can damage the compound.
- Warm the Vial Gently: Place your sealed vial into the hot water. Crucial Warning: Keep the water level below the rubber stopper. You do not want water seeping into your sterile oil.
- Swirl to Dissolve: After a minute, gently swirl the vial. You will see the crystals slowly melt away. Avoid shaking aggressively, as this creates air bubbles.
- Check for Clarity: Once the solution is completely clear and uniform, the steroid oil crystallization winter issue is resolved. Your product is good to go.
Preventing This in the Future
While we package shipments carefully, we cannot control the weather. To minimize the risk of steroid oil crystallization winter, try to have your packages held at the local depot for pickup, or ensure you are home to bring them inside immediately upon delivery.

The Bottom Line
If your NPP looks like a snow globe or your EQ is separated, don’t worry. Steroid oil crystallization winter is completely normal. A little warmth is all it needs to get back to 100%.

Frequently Asked Questions About Steroid Oil Crystallization
What exactly is steroid oil crystallization in winter?
Steroid oil crystallization winter refers to the process where the hormone particles in injectable steroids separate from the oil solution due to cold temperatures. When vials are exposed to freezing or near-freezing conditions during transit, the oil thickens and the dissolved hormone precipitates, forming crystals or a solid mass. This is a physical reaction, not a chemical one, meaning the product's potency remains intact. As noted in pharmaceutical research on injectable oil vehicles, this "wax formation" is a known behavior of oil-based solutions stored in cool environments.
Which steroids are most affected by winter crystallization?
While any oil-based injectable can crash in extreme cold, steroid oil crystallization winter is most common with high-concentration products and heavy esters. These include:
- NPP (Nandrolone Phenylpropionate)
- EQ (Boldenone Undecylenate)
- Sustanon
- Trenbolone Enanthate
- Masteron Enanthate
These compounds hold more hormone per milliliter, making them more susceptible to crashing when temperatures drop.
Is crystallized steroid safe to inject?
No—never inject crystallized gear. If you attempt to inject a vial suffering from steroid oil crystallization winter, the hormone concentration will be uneven, and the crystals could cause pain, irritation, or even tissue damage. However, once you reverse the crystallization using gentle heat, the product becomes perfectly safe and effective. The crystallization process does not compromise sterility or potency; it simply requires restoration before use.
How do I fix crashed gear at home?
Fixing steroid oil crystallization winter is simple and safe if done correctly:
- Heat water to hot but not boiling (around 140-160°F or 60-70°C).
- Place the sealed vial in the water, keeping the level below the rubber stopper.
- Let it sit for 2-3 minutes, then gently swirl.
- Repeat until the solution is completely clear.
- Wipe the stopper with alcohol before drawing.
This method is widely used and confirmed effective by users in community discussions like this thread on crashed EQ.
Can I use a microwave or stove to heat my vial?
Absolutely not. Never use a microwave, open flame, or direct stovetop heat to fix steroid oil crystallization winter. Microwaves heat unevenly and can create "hot spots" that degrade the hormone or even cause the vial to crack or explode. Direct flame can burn the oil and destroy the compound. Always use the gentle warm water bath method described above.
How long does it take for steroids to crystallize in cold weather?
Steroid oil crystallization winter can happen surprisingly fast. If a vial sits in freezing temperatures—such as inside an unheated delivery truck or on a cold doorstep—for just 2-4 hours, crystallization can begin. Overnight exposure almost guarantees a fully crashed vial. This is why we recommend tracking your shipment and bringing it indoors immediately upon arrival during winter months.
Does crystallization mean my steroids are underdosed or fake?
Not at all. In fact, steroid oil crystallization winter is often a sign of a properly dosed, high-quality product. Underdosed or heavily diluted oils contain less hormone and are less likely to crash because there isn't enough concentration to precipitate out. While not all quality products crash, seeing crystallization is actually a reassurance that your gear contains the hormone content it claims.
Can I prevent my steroids from crystallizing during shipping?
While we cannot control weather conditions during transit, you can take steps to minimize steroid oil crystallization winter:
- Request hold for pickup: Have your package held at the local post office or courier facility and pick it up yourself.
- Schedule delivery: Arrange for delivery on a day you know you'll be home.
- Insulated packaging: Some customers reuse insulated thermal bags or request additional insulation during checkout (where available).

What if gentle heating doesn't fix my crashed vial?
In rare cases, steroid oil crystallization winter may be stubborn, especially with very high-concentration compounds. If multiple gentle heating attempts don't fully restore clarity, contact our support team. We stand behind every product we sell. Do not attempt to use the vial if it remains cloudy or crystallized, and do not try more aggressive heating methods, as this can damage the hormone.
