Consider dropping the HCG dose to see the effect on serum DHEA. I doubt that the T-cyp is driving it up. However, we do know that HCG will stimulate steroidogenesis in both the testicles and adrenals. DHEA is an upstream hormone in the steroid pathways, so HCG may be the root stimulus. Why it's getting stuck at DHEA and not converting to Androstenedione, I don't know.
