100 mg per ml in a 10 ml Vial

The concentration is 100 mg per ml. Other npp steroids in this catalogue reach 150 mg per ml or higher, which changes the volume needed per milligram. The Gomeisa Labs npp steroid vial is labeled at 100 mg per ml as well, across the same 10 ml volume. Xeno Labs offers the same strength and size under its own Npp 100 listing. Where a buyer is weighing presentations at this concentration, the difference lies in maker, packaging finish and batch consistency rather than in what the label states.
