You’ve got questions? We’ve got answers!
Where are you located?
We are currently located on the west side of Colorado Springs in the Old Colorado City area at 2501 W. Colorado Avenue, Suite 204. Our building has both stairs and an elevator for easy accessibility.
How does The Good Lab test?
For potency we use a Thermo Finnegan High-Performance Liquid Chromatograph (HPLC) with a Photo Diode Array (PDA) for enhanced detection. We continually monitor our methods, processes and procedures for results you can rely on. HPLC is considered to be the preferred method for testing potency because it can differentiate between acid and active cannabinoids.
What do you test for?
We offer a 10-Cannabinoid Potency Profile (THC, THCA, THCV, CBD, CBDA, CBDV, CBN, CBG, CBGA & CBC), expressed as a percentage by weight. We will be expanding to include terpene testing in the near future.
How accurate are your results?
Our adherence to rigorous methodological standards provides the most accurate results obtainable; however, the precision of the result is always tied to the quality of the sample provided.
What sets you apart from other labs and why should I use your services?
As a consulting lab, we are dedicated to providing information our clients can use. We provide testing services with easy-to-read results, and we talk with you about what those results mean and where to go from there. We are not required to report results to the state.
How long does it take to get my results?
Our typical turn-around time is 7-10 business days. Additional rush charges apply for faster processing.
How do I get my samples to you?
Our preferred method is to arrange a drop-off at our location (courier deliveries accepted). Currently, we can schedule a pick-up within the metro Denver-Boulder-Longmont-Castle Rock area for an additional fee. If neither of these options is workable, hemp samples can be shipped to our location. Procedures for preparing samples for shipping will be provided when you sign up as a customer.
For hemp or CBD, we prefer that customers use FedEx or UPS, then text or email the tracking number to us so that we can watch for delivery. Please select the NO SIGNATURE REQUIRED option.
What about the U.S. Mail?
With the passage of the 2018 Farm Bill, the US Postal Service (USPS) has stated that it will allow hemp and CBD products to be transported through the mail if they follow specific criteria. Postal customers must provide a signed self-certification statement and documentation confirming the hemp producer is licensed through a state agriculture department. (We have incorporated this into our Chain of Custody.) Hemp mailed through USPS should have THC levels at or below 0.3 percent to comply with federal law.
Read the official statement from the United States Postal Service at Marijuana Moment.
Federal law prohibits the transfer of marijuana products through the U.S. mail system, requiring all samples of marijuana to be hand delivered to us. However, the only way to really know if a sample is hemp or marijuana is to test it. Please do not knowingly ship marijuana or marijuana products to The Good Lab.
How much does it cost?
Cost depends on the type of test and the type of sample we’re testing. Check out our current prices here. We offer discounts for bulk sample submission and ongoing testing plans. For more information, please contact us.
How do I pay?
Payment is due when samples are submitted. We will not release test results until payment has been received. We accept cash, checks, credit/debit cards or Paypal and offer bulk discounts, patient pricing and seasonal specials.
What size sample of industrial hemp do you need?
Best Bud – 2-3 grams
It is what it says it is. Pick your best bud, at least 2 grams, dried and cured the way you would consume it, and submit it for testing.
Plant Average – 3-5 grams
Take several small samples from the top, middle and bottom of the plant, as well as from all sides. Make sure they are dried and cured to level at which you would use them. Grind them, mix together well, and submit at least 2 to 3 grams from that homogenized sample batch.
Crop Average – 3-5 grams
Take several small samples from plants that are the best representation of your crop. Make sure they are dried and cured to level at which you would use them. Grind them, mix together well, and submit at least 2 to 3 grams from that homogenized sample batch.
Biomass – 1 ounce
Take multiple samples from throughout the batch or bag. Take samples not only from the top but also from several spots in the middle. Grind and homogenize it in the same way it will be processed and submit one ounce from that homogenized sample batch.
Extracts, Concentrates, Isolates – 1 gram
Be sure your batch is fully homogenized before you take a sample. As some concentrates sit, they may separate causing inconsistent results due to inaccurate sampling.
Liquids, Tinctures, Infused Oils* – 5 milliliters minimum (about a teaspoon)
We prefer to sample tincture products from the original bottle to reduce the risk of leaking or contamination and ensure better homogenization. We will return any unused portion to you upon your request. If you take the sample, please shake/stir the container well to be sure the cannabinoids are evenly distributed for an accurate sample.
Edibles, topicals, salves, exotics
Please contact us to discuss your product and the best sampling technique and sample size to achieve the most accurate test result.
