What to check when buying Testosterone
Five things worth confirming before an order, and why each one changes what you receive.
Reference only. This page covers what the compound is, how it is presented and how it is handled. It does not give dosing protocols or administration schedules, and it is not medical advice.
| Check | Why it matters |
|---|---|
| Batch documentation | A certificate of analysis should name the batch, the method and the date. For Testosterone the certificate is the only thing that ties a stated purity to the vial in front of you, so a certificate with no batch number is not evidence about your item. |
| Presentation | Testosterone is supplied as an oil solution for intramuscular injection, supplied as single esters or blends. Common esters: propionate, isocaproate, enanthate, cypionate, undecanoate. Confirm the listing matches that before comparing it against anything else. |
| Stated strength | Compare on cost per milligram rather than cost per unit. Where a listing states no strength, no cost per milligram can honestly be calculated for it. |
| Storage on arrival | Stated storage for Testosterone is: Room temperature, out of direct light. Crystallisation in cold conditions is a physical change, not degradation, and redissolves with gentle warming. Anything supplied refrigerated should arrive cold, and the batch documentation rather than the listing is the reference for what the conditions were. |
| Where it ships from | Stock held in the UK clears no customs and carries no import step. For Testosterone that is the single largest difference in how quickly an order arrives. |
