I saw on one thread someone recommending to cycle the DHT blocker as well, but that does not make any sense to me. In what way would having increased DHT for a week mimic a womans cycle?

Hmm, this a coincidence… I made the whack-a-mole statement years ago in happyme's (bobbie) DHT thread.

In my experience, Reishi and Green Tea are an effective combination for NBE. The anti-androgens in both have strong anti-cancer fighting properties that block DHT production. Androgens (& DHT) production doesn't take a break, so cycling anti-androgens seems pointless… unless you've suppressed them enough to below female range then I'd say you might be able to skip a day. And following (or mimicking) the female menstrual cycle and approach when used with NBE (or HRT) doesn't make sense either because we don't have ovaries, in other words it's pointless.
There's additional information to address when dealing with androgen production like the negative feedback loop and how it relates to extreme androgen production and how it relates when first starting any NBE/HRT production.
If you're planning on using HRT meds I've provided two anti-androgens to consider.
Bicalutamide and Dutasteride are used in HRT programs, and their side effects are listed below. Bica doe

ISBN 978-3-319-42622-8. Bicalutamide is the most widely used antiandrogen in the treatment of prostate cancer. [...] Common side effects [of bicalutamide] include breast enlargement, breast tenderness, hot flashes, and constipation as well as feminization and changes in mood and liver as well as lung toxicity; monitoring of liver enzymes is recommended during treatment (Schellhammer and Davis 2004).
Adverse events of bicalutamide, such as hot flushes (9.2% vs 5.4%), decreased libido (3.6% vs 1.2%), impotence (9.3% vs 6.5%) and abnormal liver function tests (3.1% vs 1.7%), Wellington K, Keam SJ.

The two predominant naturally occurring androgens are testosterone (T) and dihydrotestosterone (DHT). DHT is the more potent androgen in vivo and in vitro. All androgen-responsive genes are activated by androgen receptor (AR) bound to either T or DHT and it is believed that AR is more transcriptionally active when bound to DHT than T. The two classes of antiandrogens, presently available, are the steroidal derivatives, all of which possess mixed agonistic and antagonistic activities, and the pure non-steroidal antiandrogens of the class of flutamide and its derivatives.

It looks like it has a surge (of T) in the first 30-45 days, most likely from negative feedback of luteinizing hormone. This surge (or flare as they say) also happens to a lesser extent when starting PM, and from my experience BO did the same thing at first. Lower T can have a strong impact on libido, lower Total T (& freeT) can affect penis size too. I have found success in using testosterone cream or gel applied directly on the penis, if used correctly (1x per week). It doesn't impact T levels like you'd think because the application is absorbed directly to penile skin. What T does get into the bloodstream is negligible. Results vary, I can say the application has a definite impact on libido and penis size and girth.
Adrenal DHT has some impact, SRS would make them more apparent though.
Long term?, imo it's a top tier anti-androgen. I wouldn't use it just for NBE unless you seek the kinda of results as in hrt. My experience with dutasteride was approximately 12 months. Though my hrt doctor (Dr. Powers) put me on dutasteride two days a week recently because my DHT went up a bit from my last blood test. However, the rise in my DHT had no impact on my estradiol (or my free E2 percentage @ 2.0% which is considered optimal).
Dutasteride: A Review of Current Data on a Novel Dual Inhibitor of 5 Reductase
http://www.ncbi.nlm.nih.gov/pmc/articles...4_0203.pdf
Dutasteride: How Does It Work?
DHT synthesis is catalyzed intracellularly by 5 reductase types 1 and 2 enzymes. Dutasteride is the first dual inhibitor of both 5 reductase isoenzymes. This leads to near-complete suppression of serum DHT—more than 90%, compared with the 70% seen with finasteride. Type 2 5 reductase is the predominant isoform in normal prostate and in BPH tissues. Type 1 5 reductase is present in BPH tissue in lower quantities, but it predominates in prostate cancer cell lines and seems to be over-expressed in some prostate cancers. Theoretically, the greater suppression of DHT arising from the dual 5 -reductase inhibition could result in greater efficacy than is observed in selective type 2 inhibition, and this dual inhibition could prevent type 1–mediated synthesis of DHT.
