Some guys like SonicTemples are actually reporting temple growth on topical duta.
What are your thoughts on the safety and efficacy of topical bica?
Very good. The amounts used are so small that liver toxicity does not play a role, and there are some reports available of very good results with topical Bica. The main problem is solubility, which is very poor. DMSO should not be used in my opinion (furthermore, it makes you and everything you excrete smell like rotten eggs), which leaves a pure ethanolic vehicle. Since the half-life is so long, a good protocol would probably something along the lines of:
1mg/mL Bicalutamide in 98% ethanol (maximum solubility)
Once or twice per week, light needle the scalp with 0.3-0.5mm needles. Apply Bica solution generously. Scalp should be dry within a minute again. Should not take very long either, maybe 5 minutes give or take.
Even if we assume that DHT alone causes baldness, we have no way to completely suppress it besides HRT. Bicalutamide with a 5AP blocker does not stop baldness. If we cannot block the receptors or it does not have an effect, all that remains is to completely get rid of T and DHT. I don't think it is possible to locally destroy DHT in the scalp. Moreover, it is difficult, because people go bald not only at the temples, but also on the sides and even the back of the head, like me
The idea of HRT cycles seems to me the most feasible
Perhaps we can replace T with nandrolone, which is not converted to DHT. But the idea of HRT cycles seems to me better and safer than experimenting with substances for bodybuilders.
This is simply not true. You are projecting your n=1 case to all male pattern baldness sufferers, which is not only wrong but also dangerous. Bica may not have "worked" for you (although I still think you terminated the experiment
way too early), it can and will still work for many others. I feel sorry for you that you have had to resort to HRT to get your desired results, but fact is that the majority of people will not need it to get very satisfactory results. We do not know if we can completely eliminate DHT in the scalp, but topical Duta (possibly in conjuction with oral Duta) should come pretty close. I also disagree that HRT cycles would be safer than Nandrolone. Nandrolone is actually a bioidentical compound, found in minute amounts in the body. The skin metabolizes Nandrolone to DHN which is much less androgenic than DHT or Nandrolone itself. You cannot use 5AR inhibitors on Nandrolone monotherapy, because this conversion would be inhibited. HRT cycles are not safer because:
1. E2 is used in supraphysiological amounts; E2 is dose-dependently carcinogenic
2. Large hormonal shifts are unhealthy for literally every structure in your body
Cycles are not sustainable and should not be done. If you want to get on HRT, use physiological dosages and stay on it for life. Nevertheless, I admire your willpower and consistent documentation.
By the way, eliminating all gonadal androgens does not get rid of adrenal androgens. There will always be conversion to DHT.
