Understanding THC and THCa numbers on Persy product labels
Persy Diamonds Store carries Persy by 710 Labs products across concentrates, infused flower, carts, rosin, pre-rolls and related formats. Names such as Persy Diamonds, Snowcaps, Snowballs and Slabs make the catalogue easy to browse, but the figures beside each item tell the more technical story. THC and THCa numbers describe different compounds and should not be treated as interchangeable.
A label percentage normally reports how much of the product’s weight is cannabinoid, while a milligram figure usually describes a defined amount or serving. Those units answer different questions. A 70% concentrate can deliver a very different quantity than a 10% flower, yet a 500 mg cart may be labelled across its whole contents rather than one inhalation. Reading the unit before the number prevents most confusion.
THCa, often written THCA on testing documents, is the acidic precursor of delta-9 THC. It is usually treated as non-intoxicating in its raw acidic form and may remain after extraction or manufacturing. Heat can convert THCa into THC, so a product’s cannabinoid profile may depend on how it was made and whether it has been heated. A Persy label is therefore a snapshot of a specific formulation, not a universal measure of effect.
For Australian readers, that label knowledge should be paired with local law. Cannabis for medical use is accessed through an authorised prescription and a lawful supply pathway, while recreational cannabis remains illegal nationally. Persy Diamonds Store is based in Los Angeles, so an Australian consumer should not assume that a US checkout page, discounted price or visible age gate makes importing or purchasing these goods lawful.
What THC and THCa mean
Start by identifying what the producer means by THC. On cannabis product testing, THC normally refers to delta-9 THC, the intoxicating compound commonly sought by consumers. Some listings also state total THC, which may combine measured THC with the THC equivalent derived from THCa. The wording and units need to be read together because a percentage, milligrams per gram and milligrams per serving cannot be compared without conversion.
| Label term | What it represents | Common unit shown | Key distinction |
|---|---|---|---|
| THC | Delta-9 THC, the cannabinoid generally associated with intoxication | Percent by weight, mg/g or milligrams | A potency figure is not automatically a dose |
| THCa | Tetrahydrocannabinolic acid, the acidic precursor to THC | Percent by weight, mg/g or milligrams | Heating can convert it into THC |
| Total THC | Measured THC plus THC calculated from THCa | Milligrams or percent | Check whether the laboratory calls it total THC equivalents |
Where a laboratory reports both THC and THCa separately in the same unit, a common estimate for total THC is the measured THC value plus 0.877 times the THCa value. The factor reflects the change in molecular weight when THCa becomes delta-9 THC. For example, 20% THC combined with 2% THCa produces an estimated total THC of about 21.8%, subject to rounding and the method used.
Some documents print a total value already calculated by the laboratory, while others provide both components for customers to compare. Always check the stated method rather than reverse-engineering an unexplained figure. A collection name such as Snowcaps or Slabs does not replace the compound, unit and batch details needed for a proper interpretation.
Percentage and milligram labels
Percentage labels are most natural for dense flower, rosin and other concentrates because they express cannabinoid mass as a share of total weight. A result shown as milligrams per gram can be converted: 60 mg/g equals 6% by weight. If a rosin is labelled 60% THC, a 100 g sample would contain about 60 g of THC. That does not mean a 60 mg dose. The serving weight is still needed: 0.1 g would contain roughly 60 mg, while 0.2 g would contain roughly 120 mg.
Cart labels often use milligrams per cartridge and sometimes add milligrams per serving or per puff. The net amount can be shared over several uses, so dividing the total by an assumed puff count is only an approximation. A 500 mg cart consumed in five equal portions would average 100 mg per portion, but draws vary in size and some material may remain. The label organises the product; it does not make every serving identical.
Flower and pre-roll packaging introduces another layer. Flower may show a combined percentage for THC and THCa, a THC percentage for a specific amount, or the total milligrams in the bag. Pre-rolls commonly list milligrams per joint, yet the actual distribution through the paper can vary. Across formats, the fair comparison is milligrams in the portion used against THC plus any converted THCa, rather than comparing the largest headline number.
Why heating changes THCa
THCa and delta-9 THC are chemically different compounds. Decarboxylation removes a carboxyl group and turns the acidic compound into THC. The process occurs during smoking, vaping or other heating, and it may occur partly during curing, extraction or product preparation. This is why raw flower and a manufactured concentrate can present different balances even when they came from related source material.
Temperature and time influence the conversion, but neither a home method nor a device setting creates a reliable personal dose. Hardware instructions can clarify operation and safety; manufacturer information such as Geek Bar Pulse guidance should never be used to estimate the THC produced from a Persy cart. Persy’s own directions and the laboratory result are the relevant sources for a particular cannabis product.
A label may list a small THCa percentage because testing found a little of the acid alongside THC, or because the extract deliberately retains it. If the product is already decarboxylated, THCa may be minimal even though the label gives a high THC figure. Total THC is often more informative for heated products because it estimates what may be present after conversion, subject to the test method and the degree of heating actually reached.
Reading Persy product formats
Concentrates from collections such as Persy Diamonds and Snowcaps require close attention to both net weight and percentage. Two products can show the same 70% THC while weighing different amounts, so package totals may differ sharply. The word “Diamonds” in a collection name does not encode a laboratory result. THC remains the clearest potency figure, while terpene percentages and aroma descriptions address different attributes.
Infused flower should not be confused with naturally dried flower carrying its own cannabinoid profile. An infused product may have THC added through a carrier oil or another infusion process, which can produce a higher or more uniform number than the base material alone. Look for wording that identifies the format and explains whether the percentage describes the combined product. Rosin and carts may likewise be made from different starting materials and extraction methods.
Pre-roll packaging makes size and serving count especially important. A multi-pack may print a total THC amount, a per-joint amount or both, and the joint may not deliver an even share. Carts can carry THC and THCa in one formulation, while some products report almost entirely THC. A high number also cannot predict the intensity or duration of effects because dose, tolerance, inhalation and other product characteristics vary. For every format, compare net weight, tested cannabinoids, stated unit, batch and serving guidance.
A practical buying lens for Australia
Australian cannabis terminology can make familiar packaging easier to decode. A “script” is the prescription used for medical cannabis, and many patients speak of meds, flower, concentrates or vape carts rather than laboratory terms. Authorised prescribers and lawful dispensary or pharmacy supply pathways also mean that THC percentages may appear alongside product names, serving sizes and strain information. State and territory arrangements differ, making local health information more reliable than an overseas retail page.
Metric habits matter too. Australians buy flower by the gram and may see 0.5 g or 1 g quantities, while US products can use ounces, eighths and pounds. A label using milligrams per serving may be useful in a local clinic discussion, but it does not establish that a US concentrate is lawful to import. For some patients, the Specialist Evaluation and Exclusion Scheme provides a legal route for prescribed medicinal cannabis, governed by Australian rules rather than an American checkout.
Persy Diamonds Store advertises Bitcoin payments and a 15% checkout discount, as well as wholesale pricing for bulk buyers. Bitcoin is familiar to many Australians, but its price can move between quotation and settlement, a US-dollar quote adds an Australian-dollar conversion, and discount language can hide exchange-rate or network costs. Payment method does not change destination rules. Australia’s federal Interactive Gambling Act restricts interactive gambling services, and authorised online pokies are governed by state licensing; a page about online live dealer games may concern offshore operators rather than a local venue.
Whichever figure appears, the most defensible interpretation is the one tied to a named compound, explicit unit, tested batch and lawful local purchase route. Persy product names and headline percentages are useful identifiers, not substitutes for product-specific information or Australian regulatory checks.
