Like all oily solutions, Testoviron Depot must be injected intramuscularly, immediately after drawing up into the syringe, and extremely slowly (see Precautions).
For the development and stimulation of still underdeveloped androgen-dependent target organs and for the initial treatment of deficiency symptoms: 1 prefilled syringe i.m. every 2-3 weeks.
To maintain an adequate androgenic effect, 1 prefilled syringe i.m. every 3-4 weeks. Shorter injection intervals may be necessary depending on the individual requirement for hormone, but longer intervals of up to 6 weeks are also sufficient in many cases.
Serum testosterone levels should be measured before start of treatment and periodically during the treatment as recommended by current treatment guidelines.
The product should be inspected visually for particles prior to administration. Only clear solution free from particles should be used.
