Safety and Authenticity of Pürblack Live Resin

Pürblack shilajit Live resin jar opened showing contents.

At Adaptive Energy, we take authenticity and safety seriously. Pürblack Live Resin is tested under both Shilajit and Mumie standards for authenticity, purity, and safety by independent laboratories in both America and Europe.

Pürblack shilajit resin is processed at low temperatures, to protect the natural integrity of some of its more delicate biochemical constituents. We do not use harsh processing methods, and our product contains no fillers. Pürblack shilajit is an elite Live Resin exceeding all Shilajit, Mumie and Salajeet Resins in efficacy, range of effect and quality due to our unique patent-pending manufacturing process.

We publish the details of our proprietary manufacturing method, along with all information relevant to our Certificates of Analysis, establishing quality, authenticity, and elemental makeup and microbiological safety.

Close comparison of the results of our own, internal testing and analyses with those from an independent domestic laboratory will show that some of the external lab results are more favorable than our own. Such differences may be the result of our use of more stringent methodologies or differences in techniques and equipment employed.

The authenticity of Pürblack shilajit

We offer Pürblack shilajit only in the authentic and natural resin form. We intentionally do not powder our product, even though some users might consider a powdered form more convenient to use. We feel that the purity, authenticity and natural integrity of the product are ultimately more important than convenience. We believe that those serious about their health and well being agree with us on the genuine resin form. We never add powdered fulvic acid, soil extractions or dilute the product with gums or clays, for economic or any other reasons. We offer Pürblack only in its pure and unadulterated Resin form.

For a more detailed understanding of how our Pürblack Live Resin is made, you are welcome to review our patent application. Below, we will briefly outline and explain the authenticity and safety data related to our Certificate of Authenticity (COA).

Independent Lab Test features data that confirms the authenticity of the product, in particular, its pH level, solubility, percentage of ashless humic acids (by mass), non-soluble ashes (by mass) and total ashes, authenticity (acid/alkali) test, and glycine content.

The potency of Pürblack shilajit

Sometimes we receive a question about Shilajit potency, with regards to some elements being below the USDA’s RDA (recommended daily allowance). From the perspective of consumption, it is important to understand that in natural products, individual elements do not occur in their isolated forms. They are always present as part of larger molecules, which are themselves part of the makeup of vitamins, enzymes, and other nutrients. What is relevant is not the quantity of an isolated element or mineral, but rather the cumulative effect produced by the molecules containing that element or mineral.

Safety and testing results

COA and independent tests feature radiological, toxic elements, microbiological and elemental testing.

The following chart details and interprets testing results for standard and maximum doses of Pürblack dissolved in water, for the four most significant metallic elements tested:

ANALYTE Mg. in 0,5 g. serving Compared to EPA MCL Mg. in a 1 g. Serving Compared to EPA MCL for Drinking water Compared to EPA MCL for Drinking water EPA MCL mg./l Water Standard
Lead (Pb) 0.000294663405 50.9 times lower than EPA MCL 0.00058932681 25.4 Times lower 0.590 0.015
Mercury (Hg) 0.0000054937245 364 times lower than EPA MCL 0.000010987449 182 times lower 0.011 0.002
Arsenic (As) 0.00004994295 200 times lower 0.0000998859 100 times lower <0.1 0.010
Cadmium (Cd) 0.000004994295 1000 times lower 0.00000998859 500 times lower <0.01 0.005


These results and calculations demonstrate that the consumption of Pürblack Live Resin is safer than drinking water from some public sources in the US as allowed by the US Environmental Protection Agency (EPA).

Pürblack Live Resin is substantially safer than most Shilajit Resins currently offered on the US marketplace. We fully disclose all safety parameters, follow CGMP guidelines and file prior notices with the US FDA. Additionally, we present findings for some further metallic constituents, found in significant concentrations in Pürblack:

ANALYTE Milligrams per 0.5 gram serving EFSA reviewed / USDA standards Milligrams per 1 gram serving EFSA reviewed / USDA standards PPM Within normal dietary intake level?
Aluminum (Al) 1.529 (1 mg 529 µg) yes 3.059 (3 mg 59 µg) 1.6 to 13 mg. per day daily dietary / environmental exposure 3062.5 yes
Iron (Fe) 0.788 (788 µg) yes 1.577 (1 mg 577 µg) 6 – 8.1 mg. 1579.5 yes
Magnesium (Mg) 2.815 (2 mg 815 µg) yes 5.630 (5 mg 630 µg) 200-265 mg. 5637.00 yes
Phosphorus (P) 1.101 (1 mg 101 µg) yes 2.202 (2 mg 202 µg) 580 mg. 2205.50 yes

Microbiological Safety

Bacteria harmful to humans (E. coli, salmonella, staphylococcus or others) was never found in Pürblack, under stringent testing. Microbiological markers such as total aerobic bacterial count, Enterobacteriaceae, and total yeast and mold counts were all found to be below industry-standard norms.

A word on aluminum:

One asks us sometimes about the “high” aluminum content of our product, in light of the Adya Clarity scare. 

With regards to this point, it is important to note that:

Aluminum is an abundant element, occurring naturally in many foods that humans have enjoyed for millennia. If you eat lettuce, mushrooms, spinach, radish, Swiss chard, cacao, chocolate or many spices, you are exposed to dietary aluminum.

Shilajit resin has been proven safe over centuries of human consumption, and its safety has been confirmed and validated by modern research. It is quite true that some synthetically-derived aluminum-based compounds such as aluminum chloride and aluminum lactate have been proven harmful in in-vivo studies. These studies only examined synthetics, however. Aluminum from natural dietary sources is considered safe.

Pürblack shilajit is a natural dietary source of aluminum, with aluminum levels lower than the normal, day-to-day exposure experienced in many modern, developed (“first-world”) countries.
