At Power Anabolics we take product quality seriously. Every brand we list is subject to independent third-party laboratory testing so customers can be confident that what is on the label matches what is in the vial, ampoule or tablet. Testing covers three core areas: identity of the active ingredient, dosage accuracy against the stated label claim, and purity — meaning the absence of unexpected compounds, solvents or contamination.
We do not perform any testing in-house. All samples are submitted to accredited UK and EU laboratories that specialise in pharmaceutical-grade analytical chemistry. This separation between retailer and laboratory is deliberate: it removes any commercial incentive to influence the result, and it gives our customers an objective record of what they are buying.
How testing works
Our process is straightforward and intentionally boring — that is the point of good quality control. A typical batch follows the same path every time:
- Random batches are pulled from stock at irregular intervals — neither the brand nor the warehouse picker chooses what is sampled.
- Sealed units are shipped to an independent third-party laboratory under chain-of-custody documentation.
- The laboratory runs analytical techniques such as HPLC (High-Performance Liquid Chromatography) and, where appropriate, LC-MS (Liquid Chromatography – Mass Spectrometry) to identify and quantify the active compound.
- Results are returned as a formal Certificate of Analysis (COA) which we retain on file and reference against the batch number printed on the product.
What gets tested
A complete analysis is not a single test — it is a panel. Depending on whether the product is oral or injectable, the laboratory will report on:
- Active ingredient identity — confirming the compound present is the one named on the label.
- Potency — the measured dose expressed as a percentage of the labelled dose (e.g. 98% of 250 mg/ml).
- Purity and impurities — detection of residual solvents, degradation products or unknown peaks.
- Microbial contamination — bioburden screening on oral tablets and capsules.
- Sterility — sterility verification on injectables, where applicable to the laboratory's scope.
Reading a test certificate
A Certificate of Analysis can look intimidating at first glance. The key elements to focus on are:
- The HPLC chromatogram — a graph of detector response over time. A clean batch shows one dominant peak at the expected retention time and minimal background noise.
- The dosage match — the reported concentration expressed as a percentage of the label claim. Industry-acceptable pass thresholds are typically ≥95% potency, though our internal target is tighter.
- The conclusion line — most COAs end with a plain-language pass/fail or "within specification" statement.
Brands and batches we test
The following authorised brands are part of our rolling third-party testing programme:
- PharmaQO
- Proper Labs
- Balkan
- Evotech
Testing is performed on a rolling basis rather than batch-by-batch in real time — meaning at any given moment some batches will have a recent COA on file and others will be in the queue. We reserve the right to reject or withdraw any batch that does not meet our internal pass thresholds, regardless of brand.
Frequently asked questions
Do you test every single batch?
No. We operate a rolling sampling programme across all authorised brands. Testing every individual batch in real time is not commercially feasible for any retailer; what matters is consistent, randomised oversight over time.
Where can I see results for a specific product?
Batch-specific results are not published openly on the site. If you would like to see the COA for the batch you have received, contact us with your order number and the batch code printed on the product.
What happens if a batch fails?
Batches that fall outside our pass threshold are pulled from sale, the supplier is notified, and any affected customers are contacted. We would rather lose stock than ship something that doesn't match its label.
Are these tests UKAS / ISO accredited?
We work with laboratories operating to recognised analytical standards. Accreditation scope varies by laboratory and by test type — we are happy to confirm the specific accreditation status of the lab that handled a given COA on request.
