From the Guidelines

Testogel 50mg sachets contain 50mg of testosterone in 5g of gel, resulting in a concentration of 1% (10mg/g), and to accurately measure 1.25mg of testosterone daily, you would need to apply 1/40th of a sachet, which equals 0.125g of gel. According to the study by 1, Testogel 1% gel comes in gel packets with 50mg in 5-g packet, and the typical dose range is 50-100 mg/d. Measuring 1.25mg daily would be extremely challenging without specialized equipment.

Some key points to consider when using Testogel include:

  • The application site is the skin of the back, abdomen, upper thighs, and upper arms
  • The advantages of Testogel include easy application and good skin tolerability
  • The disadvantages include potential for transfer to partner or child by skin-to-skin contact and higher cost compared to other formulations

Given the difficulty in accurately measuring such a small dose, it may be beneficial to discuss alternative testosterone formulations with your healthcare provider that allow for more precise low-dose administration. The challenge with such a small dose is that testosterone gel is designed for higher dosing regimens, typically starting at 50mg daily for adult males with hypogonadism. If you require such a low dose (1.25mg), it may indicate you need a different treatment approach or formulation altogether. Improper measurement could lead to inconsistent hormone levels, potentially causing side effects or reduced effectiveness of your treatment.

From the Research

Dosage Concentration of Testogel

  • The dosage concentration of Testogel is 1% testosterone gel formulation, which means it contains 1% testosterone by weight 2.
  • A 50mg sachet of Testogel contains 1% testosterone, which is equivalent to 0.5mg of testosterone per 5g of gel 2.

Accurately Measuring 1.25mg Daily

  • To accurately measure 1.25mg of testosterone daily, it is essential to use a precise measuring device, as the standard application is 50mg or 100mg per day 2.
  • However, there is no direct information available on how to accurately measure 1.25mg of testosterone from a 50mg sachet of Testogel 3, 2, 4, 5, 6.
  • It is crucial to note that showering 15 or 30 minutes after application of testosterone gel can significantly reduce plasma testosterone levels 6, which may impact the efficacy of the treatment.
