that's dumb as hell and these kinds of "articles" are really why bro-science gets such a bad rap.
if someone wants to have continued endogenous test production while on cycle, they can just run HCG and blast 4 grams a week or whatever. running a pct for 1 month and then an extra 4 months during a "bridge" (using an oral to bridge nonetheless) just so the body can spurt out a fraction of normal test production, is pointless, and a good way to lead to long term htpa impairment/suppression
when you see people basing mathematical numbers and reaching "scientific" conclusions off of unfounded broscience, it's called a compounding error and a gaurenteed way of determining that the hypothesis is a bunch of manure
