I should have specified as you seem confused by my wording. If IM administration of methylated compounds nullified the liver toxicity by that great of a margin then there wouldn't be an oral methylated steroid market as everyone would be injecting their methylated compounds as then they could do it for a longer duration. The difference would most certainly be negligible in my opinion which is why people still orally take methylated compounds vs injecting them.
The methyltrienelone is more than likely dissolved in oil for injection because it makes dosing things on a microgram scale easier as a solution is homogeneous, same distribution of hormone throughout where as making a powder capsule or pressed pill could yield "hot spots" where the concentration is higher. That could end disastrously for something active and potent in the microgram dosing range.
