It sucks that those links are broken, but I'm just gonna copy and paste part of a post I wrote a while back regarding this topic.
"the percent change of DHT for placebo and .01 mg finasteride were identical and essentially zero within a reasonable statistical estimate. The change dropped by 60 % for a .05 mg dose and stayed that way for all dosages up to 5 mg. Thus a 20 times smaller dose than PROPECIA had the same effect on the DHT."
"Thus the fact that the dosage has been set by the manufacturer at a level far larger than the level measured as necessary for the main function, has not been reported publicly. Yet, the vastly lower dosages, reported in the data submitted to the FDA, would be expected to reduce the chance of side effects."
So, if such a small dosage of Fin has the same inhibiting effects on DHT, why would Merck recommend such a higher dosage??? Especially on a person who is just starting out on it. It makes no sense to me, seems like they are not only condoning, but recommending their consumers to take a USELESS risk.
Any thoughts on this would be appreciated!
Now, there were no efficacy tests done for dosages of 0.05mg-0.2mg (not sure why), but there were for 1mg and 0.2mg. However, the sample of participants (100) was small and the differences between the .2 and 1.0 dosages in the first two cases were not apparent and, in the photographic assessment, which showed a larger mean improvement for 1 mg, the values overlapped statistically at the 95% confidence level. ---> 68.7
+/- 17.3 and 54.9 +/- 17.
From the looks of it, Merck/FDA did not care to thoroughly look into the effectiveness of a lower dose. Why? Beats me.
Another excerpt from one of the articles which basically sums up the whole situation nicely.
"I cannot understand why saving money ``cannot be condoned'' when the cost is approximately $1000 per year, not covered by insurance, and the drug must be taken forever in order to preserve any hair growth.
There are no data proving that the lower dosages are ineffective while the physical T to DHT conversion measurements are flat from .05 to 5 mg. Considering the cost to take the drug for the rest of one's life and
that the drug is too expensive for most young men, an intelligent user might want to do a few month trial at lower dosage. Nothing to lose but some fuzz."
I've been reading about hair loss for about a month, I'm no expert, but so far this is what stuck out to me the most. I know for sure if I go on propecia, I'm starting at 0.25mg and taking it days apart to start.
If you didn't read it all, I guess the most importnat piece of info relating to your thread, is, if you are going to go on a low dosage, do you go for 0.05 or 0.2??? It should have a similar effect right? But atleast we know 0.2 yielded good results, and personnaly i rather take that so i can cut up the pills instead of dissolving them.
