Fellows - On Feb. 7th Dr. Crisler was interviewed by Carol Lanore on his Internet radio show Super Human Radio. Crisler has been interviewed by Lanore many times the past few years (see all interviews on the link below) and I find them all extremely interesting and another way to build knowledge.
You will hear Crisler speak to SQ vs IM testosterone injections by following the first link titled "Sub Q Injections: How, Where and How Much" on the link below. You will also see Crisler's other links to past interviews some of which are rich in learning as you will hear the insights of one of the leading Physician's in TRT. Make sure to close the space between the . and com when you past into your browser.
There are 3 interviews on this show and Crisler is the 2nd of the three so you might want to FF.
Crisler finally "gives in" to Shippen's pushing him to testing SQ with his patients. He also states clearly that there is no concrete studies on the effectiveness of SQ vs. IM especially not knowing half life via SQ.
Overall, he doesn't really see any significant issues, however, and admits to the smother levels vs the spikes "zig-zag" we see with IM and thinks SQ may be on the cutting edge of injections.
He'll even give you his injection protocol as well but what I found interesting is he recommends that a man not inject more then 40 mg at one time...which makes sense as SQ should be a more frequent injection cycle vs IM.
Enjoy my friends!
