Nerolidol versus terpinolene: Galaxy Walker OG and Lilac Diesel from the same three producers

How do these two strains really differ?

In composition and lineage, not potency. The terpene profiles of both strains list eight names, seven of which are common; only nerolidol stands alone on the Galaxy Walker OG side and terpinolene on the Lilac Diesel side. The lineages do not share a single common ancestor, and the recorded range of THC content is identical.

That one name on each side is also the leading terpene. Nerolidol leads in the Galaxy Walker OG profile, terpinolene in the Lilac Diesel profile, and both belong to the minority in this cluster: nerolidol is at the forefront in 6 cultivars out of 85 described, terpinolene in 7. The top three, namely caryophyllene, myrcene, and limonene, account for the remaining 66 entries. A pair where both sides carry a leading terpene outside of this trio is not the norm in this comparison.

The lineages diverge even more clearly. Galaxy Walker OG has two parents in the data, Skywalker OG and OG Kush, with the latter being a broad family of style and appearing in the lineage of four cultivars in this cluster, along with Galaxy Walker OG itself. Moreover, OG Kush is listed in the same comparison as a separate strain, one for which its own origin has not been established. Lilac Diesel originates from four breeding lines of Ethos Genetics. Its lineage includes Silver Lemon Haze and Forbidden Fruit, alongside NYC Cherry Pie and Citral Glue; none of these four names reappear in the lineage of any other strain from this cluster.

The genetic label is even inconsistent. For Galaxy Walker OG, one source describes it as a hybrid, while another refers to it as an indica strain. For Lilac Diesel, the records diverge into three variants, from hybrid to hybrid with a sativa dominance to pure sativa. The division into indica and sativa here is a commercial description, not a determination, and is not suitable as the axis of this comparison.

What connects them?

The shelf, not the origin. Both strains are supplied in Poland by the same trio of producers: S-LAB, Synoptis Pharma, and Tilray. Both have the same recorded range of THC content, share seven out of eight names in their profiles, and both have an empty sibling list. The pedigree graph connects them in no way.

The recorded THC content range for both strains, 16.2-24.2%, is not the range of a single declaration. It arises from the combination of several separate registry entries with different nominal strengths: on the Galaxy Walker OG side, there are four such entries, on the Lilac Diesel side, six, and each has its own tolerance around its declared value. The lower end comes from the weakest entry, the upper from the strongest, and no pharmacy entry covers the entire range by itself.

A common trio of producers also means that both strains follow the same approval path and have the same form. The complete listing of positions for each of them is on separate pages: in the strain description. Galaxy Walker OG oraz w opisie odmiany Lilac Diesel.

What is not common in this data is the ancestor. The parents of Galaxy Walker OG do not appear in the lineage of Lilac Diesel and vice versa, and the empty sibling list on both sides is not a gap to be filled. A parent that is a broad family of style, like OG Kush, does not generate siblings, as it is a breeding category, not a single identified strain.

Do both Polish databases describe these profiles the same way?

No, and this is true on both sides of the pair. Two Polish listings provide a different profile composition for each of these strains, so none of these profiles is confirmed consistently by the sources. For Galaxy Walker OG, the discrepancy concerns humulene, linalool, and pinene; for Lilac Diesel, bisabolol, humulene, limonene, and myrcene.

The direction of this discrepancy is not the same on both sides, and that is more interesting than its size. For Galaxy Walker OG, everything listed by one database is also on the list of the other: the shorter entry fits entirely within the longer one, and three names are added exclusively by the more extensive one. For Lilac Diesel, no entry contains the other, as each carries something that is not present in the other.

This leads to something that is not visible until both sources are compared separately. In the database describing the profiles more extensively, these two strains appear almost the same: they share seven names out of eight. In the other database, where the entries are shorter, two names remain common from five on each side. Thus, the same pair is once almost one profile and once two different ones, depending on which side is read. Competition does not show this, as it copies one source at a time.

Therefore, we do not place numbers next to the names in the composition. The sum of entries in the share table is 58 for Lilac Diesel and 100 or 102 for Galaxy Walker OG, depending on the registry entry, and this is within one database. If these numbers were shares of the whole, no sum could exceed one hundred or fall significantly below. The denominator is unknown, so a number that looks like a measurement would be worse here than its absence.

Is a different leading terpene visible during vaporization?

Not in a form that could be verified on a device. The project database records for terpinolene entries around 184 degrees Celsius at atmospheric pressure, and for nerolidol, one entry at 275-277 degrees without specified pressure, so both numbers cannot be compared as two measurements of the same kind.

The gap between these entries reaches nearly ninety degrees, but we cannot draw a conclusion about vaporization from it. The vaporizer setting does not equal the temperature of the dried flower in the chamber, and the boiling point of a pure compound in a flask does not indicate when the same compound leaves the plant material in a mixture with dozens of others. The dried flower is dispensed by a doctor's prescription, so the method of administration is determined by the attending physician, not the informational side.

For the very question of the difference between these strains, something else is more important: no work compares the leading terpene with what the patient feels after vaporizing a specific pharmacy entry. The temperature records come from chemical databases and describe pure compounds, not pharmacy dried flower. This is the boundary of the data, not editorial caution.

What is known, and what is not known about the effects of both strains?

No clinical study has been published for either of them. Everything that can be cited relates to individual terpenes in animals or in vitro, and not to dried flower labeled Galaxy Walker OG or Lilac Diesel. Below is the state of evidence separately for both sides of the pair, along with its boundaries.

Nerolidol has two studies, both conducted on mice. Fonsêca et al. (2016, Fundamental & Clinical Pharmacology, PMID:26791997) described that at doses of 200-400 mg/kg, it reduced the number of abdominal cramps induced by acetic acid in mice and lowered the levels of pro-inflammatory cytokines, linking the mechanism to the GABAergic system. Hojjat et al. (2026, Arquivos de Neuro-Psiquiatria, PMID:42447923) administered it orally at doses of 25-100 mg/kg and noted a longer latency to seizures induced by pentylene tetrazole and lower markers of oxidative stress in the brain. It has not been shown that nerolidol alleviates anxiety or insomnia in humans; both available studies concern rodents and describe analgesic, anticonvulsant, and antioxidant effects, not sleep or mood.

Terpinolene also has two studies, and they are even further from the patient. Ito and Ito (2013, Journal of Natural Medicines, PMID:23339024) described a calming effect after inhalation in mice, which persisted even in animals with impaired olfaction, indicating the absorption of the compound, not just the perception of the smell. Okumura et al. (2012, Oncology Letters, PMID:22740904) worked on a human leukemia cell line K562, that is, in vitro, and measured the level of AKT1 protein. No effect of terpinolene on pain, anxiety, or sleep has been demonstrated in humans or in any animal pain model; available data only include a calming effect after inhalation in mice and an impact on the leukemia cell line in vitro.

These two sets cannot be transferred onto each other. The studies on nerolidol say nothing about Lilac Diesel, the study on inhaled terpinolene says nothing about Galaxy Walker OG, and none of the four examined dried flower, only the isolated compound in a dose that cannot be measured from the pharmacy.

How long does one last, and how long does the other?

Identically, because the rate and duration of the episode depend on how the raw material enters the body, not on what is on the label. Neither of these two strains has its own pharmacokinetic study, so the leading terpene does not provide a number that could be fairly compared.

The route of administration determines the course more than the variety itself. After vaporization, the substance passes from the lungs to the blood almost immediately, so the first sensations appear after a few minutes, the intensity increases for another ten to thirty minutes, and the whole effect lasts for two to four hours. After ingestion, the raw material first passes through the intestine and liver, so the first sensations are awaited from half an hour to two hours, and the episode can last six, sometimes eight hours. Hence the most common mistake with oral administration: anyone who thinks nothing is happening after thirty minutes and takes another dose will receive both doses at once. The above ranges describe the route of administration, not this variety; pharmacokinetic studies for a single cultivar have not been published.

From this comparison, one conclusion arises: the question of which of these two strains lasts longer does not have an answer based on strain data. It has an answer based on whether the substance reaches the lungs or the stomach, and that answer is the same on both sides of the pair.

What side effects have been reported for each of these two strains?

None, if you ask about the difference between these two names. Public data do not separate reports by cultivars, so there is no dataset from which one could read that something was reported more frequently after one of these strains than the other. Below is what is known about dried flower as a group of substances.

Reports of adverse effects are collected for medicinal products with a batch number, not for the strain name, so the following pertains to hemp dried flower as a group of raw materials. The most frequently reported symptoms are dry mouth, red eyes, and increased heart rate. Dizziness upon rapid standing, daytime drowsiness, and temporary worsening of short-term memory are less frequently described, as well as anxiety that increases with dosage. A separate issue is medications taken concurrently, especially sedatives and those affecting coagulation: their assessment requires knowledge of the entire list of preparations, not just the description of the plant. We do not provide the frequency of these symptoms numerically, as public compilations for hemp dried flower in Poland do not separate them by individual products.

One thing distinguishes these two products in a verifiable way: the number of registered products on the market. Lilac Diesel has six, Galaxy Walker OG has four. If someone were to count reports by strain name, this inequality alone would give a higher number to the strain that has more registered products, and it would not be evidence of a worse safety profile. The denominator, which is the number of packages issued, determines this, and that information is not publicly available.

Is either of them currently available at the pharmacy?

This changes from week to week, and no informational site can determine this. In a snapshot collected for this compilation, one of the four Galaxy Walker OG products was available and three of the six Lilac Diesel products, but shelf status depends on the batch, import, and validity of the permit.

Availability changes because each registered product is a separate batch introduced by a different manufacturer, and a gap from one of them does not close the strain in pharmacies as long as another has stock. With six products, the chance that at least one is currently available is often greater than with four, but this is a characteristic of the market, not the plant.

The current status of the entire compilation is maintained in a separate overview of available medical marijuana strains.Hemp flower is a pharmaceutical substance issued by a doctor's prescription in the Rpw category, so the choice of product is determined by the attending physician. The dried flower category is a different shelf: it includes dried flower from industrial hemp, available over the counter and with THC content below the legal threshold, and not the pharmaceutical substance described on this page.

Frequently Asked Questions

What is the difference between Galaxy Walker OG and Lilac Diesel?

The leading terpene and lineage. The profiles of both strains have eight names, of which seven are common; nerolidol stands alone for Galaxy Walker OG and terpinolene for Lilac Diesel. The lineages do not share a common ancestor, and the recorded THC content range is the same for both.

Which of them has more THC?

None. Both have the same recorded THC content range in the data, as they both appear in registered products with the same nominal strengths. Therefore, strength is not a criterion by which these two strains can be distinguished.

Does nerolidol or terpinolene change anything for the patient?

It is unknown. Research on both of these compounds has been conducted on mice or in vitro, on isolated compounds, not on dried flower. Neither indicates how the profile composition translates into effects in humans after vaporizing a specific pharmaceutical product.

Why don't you provide shares in the profile as numbers?

Because the denominator is unknown. The total of entries in the share table is 58 for Lilac Diesel and 100 or 102 for Galaxy Walker OG, depending on the registered product. A value that sometimes exceeds one hundred and sometimes ends well below is not a share of the whole.

Are these two strains related?

The data shows nothing that connects them. Galaxy Walker OG has two parents, Lilac Diesel has four, and none of these terms repeat on the other side. The sibling list is empty for both, which is a valid result given that the parents are broad families of style, not a lack of data.

Can they be purchased without a prescription?

No. Both are hemp flower issued by a doctor's prescription in the Rpw category. Industrial hemp with cannabidiol, available in stores without a prescription, is a different product from a different shelf and is not either of these two strains.
