From multiple professional athletes and people close to me with many years of continual use. Subq results in a 70% absorption rate. IM results in a 68% absorption rate. IV results in a 100 % absorption rate. SubQ hits much faster and IM is a slower steady release.
I am sorry but your statements are more and more unbelievable, if you are going to start quoting stats you better start listing references. BTW IM is much better at absorption than than subq just based on blood flow. Duhhhhhh. Sorry but you better start reading for yourself and thinking for yourself than believing the bs people tell you. Its your body treat it like you care and read, read and read more.
Pharmacology: intramuscular vs sub-cutaneous injections, absorption rate, steroid hormones
