Nice job Scepticore.
The accepted half life theory never completely satisfied me. What showed on paper never seemes to pan out in reality. My one criticism, or maybe curiousity is the better word, is why you used Sustanon. The prop in sus will cause a rapid hgh level of T -- far greater than cyp or enhanthate and the Isocaproate will keep BL's elevated longer. I think it would be interesting to do this testing with a single test with a supposed half life of 10-14 days. I believe it would show that multiple dosing, even with supposed "long acting " esters provides a more even BL of test.
This is why I recommend several smaller shots for HRT and why long acting compounds such as Primo still work well in a short cycle.
