[QUOTE="BigTex, post: 228809, member: 43589"] Seems I remember seeing that MCT has significantly less viscosity than castor oil. Behre HM, Abshagen K, Oettel M, Hübler D, Nieschlag E. [B]Intramuscular injection of testosterone undecanoate for the treatment of male hypogonadism: phase I studies. [/B]Eur J Endocrinol. 1999 May;140(5):414-9. doi: 10.1530/eje.0.1400414.

[HEADING=1]Abstract[/HEADING] [B]Objective: [/B]In the search for long-acting testosterone preparations suited for substitution therapy of hypogonadal men, testosterone undecanoate (TU) dissolved in either tea seed oil or castor oil was investigated. [B]Design: [/B]In study I, 1000 mg TU in tea seed oil (125 mg/ml) were injected in equal parts into the gluteal muscles of seven hypogonadal men.
