Hi Eidolon and Welcome to the Forum. Why don't you tell us a little about
yourself. Are you interested in PCa prevention, treatment?
Both of these compounds are new to me. Here is what a quick search turned up:AHCC
(Active Hexose Correlated Compound, a supplement from mushrooms)
I'm not seeing any studies on prostate cancer specific for AHCC. Here is an MSK page
(2020 update) about
"AHCC is taken to:
Improve liver function
While AHCC is used for these reasons, there isn’t enough research to say that it works. Talk with your healthcare provider before taking AHCC."
A rather expensive supplement.

"The effect of MCP on prostate-specific antigen (PSA) doubling time (PSADT) was investigated in a 2003 study. Prostate cancer patients with rising PSA levels received six PeS capsules 3 times a day (totaling 14.4 g of MCP powder/d) for 12 months. Following treatment, 7 of 10 patients had a statistically significant (P ≤ .05) increase in PSADT."
(See link for in vivo and animal studies for MCP and PCa.)
Looking at the prices online, 14 g/day for months would be extremely expensive, if we're talking about
the same strength compound.
