No: Propecia (finasteride) will not lower testosterone levels. It will, however, lower DHT levels and can raise estradiol levels. Elevated estradiol levels can lead to gynecomastia and/or breast tenderness, and/or decreased libido. ...Read more

What happens if propecia (finasteride) blocks testosterone, doesn't this mean that propecia (finasteride) will turn a man physically weak like a boy?

What happens if propecia (finasteride) blocks testosterone, doesn't this mean that propecia (finasteride) will turn a man physically weak like a boy?

5ARI & DHT: So let's get this right. Finasteride, sold as Proscar & Propecia, along w/its competitor, Dutasteride, sold as Avodart, (dutasteride) do not block testosterone but rather conversion of T into dihydrotestosterone (DHT). Therefore, neither 5 alpha reductase inhibitor (5ARI) will make a man physically weak like a boy. However, by blocking T's conversion into DHT, it may raise one's estradiol (female hormone) ...Read more

Where I'm taking Propecia (finasteride) for hair loss would I still be able to build muscle lifting since Propecia (finasteride) lowers dht and testosterone?

Where I'm taking Propecia (finasteride) for hair loss would I still be able to build muscle lifting since Propecia (finasteride) lowers dht and testosterone?

Propecia (finasteride): Hi RHyde, There have not been any significant studies that I have read that show any correlation between propecia (finasteride) and decreased ability to build muscle.

It is possible that other side effects may interfere with your muscle building activities. These include, but are not limited to, dizziness, drowsiness, and swelling. ...Read more

I’m on testosterone replacement therapy. Will asking my dr for finasteride for hair loss offset any gains from supplemental testosterone?

I’m on testosterone replacement therapy. Will asking my dr for finasteride for hair loss offset any gains from supplemental testosterone?

Not exactly: Finasteride prevents the conversion of testosterone to dht. This only occurs in certain tissues (scalp/skin ; prostate). It is thought that too much Dht causes hair loss. Using Finasteride shouldn't effect your energy level or muscle mass, however there are reports that it can effect your libido. ...Read more

I want to build muscles; training; testosterone pills, safe or dangerous?

I want to build muscles; training; testosterone pills, safe or dangerous?

Dangerous: All oral prescription anabolics have been banned for production and distribution in the U.S. Except I believe anadrol, which is fda indicated in aids accompanied with wasting syndrome. All oral anabolics are extremely hepatotoxic, meaning they will adversely affect your liver. Almost all oral anabolics available domestically would be black market drugs, from mexico, europe, or china. Avoid them. ...Read more

My 17 yo son has purchased: Test 600c (testosterone), Tren 75 (Finabolan), Var 10 (Anavar) and d-Anabol 25 (metandesenolone). Dangerous? Pls advise

Dr. Alvin Lin Dr. Lin
1 doctor agreed:

Yes, very!: If your son has "purchased" these anabolic steroids, in all likelihood, he is not under the management of his physician. Excess T from unsupervised use is very dangerous and can increase risk for heart attack, stroke, mood changes, etc. It can also render men infertile as well as shut down T production. Best to see family doc for evaluation. If he truly has low T, need to find cause first. ...Read more

Keep seeing TV ads, preaching the dangers of testosterone. My PCP has me on TRT. Should I be worried?

No free lunch: Always keep in mind that there is no such thing as a free lunch. As a corollary, no diagnostic test, surgical procedure or even medication is without risk. It's up to you & your family doc to decide if said potential risk is greater than hope for benefit. If so, don't do it. Regarding testosterone, think of Goldilocks. Not enough is bad but too much is also risky. Work w/your doc to get it right. ...Read more

Can avodart (dutasteride) stop hairloss? It reduces DHT level but it also increases testosterone. Which one is worst for the hair? Is it dangerous for the brain?

Can avodart (dutasteride) stop hairloss? It reduces DHT level but it also increases testosterone. Which one is worst for the hair? Is it dangerous for the brain?

Like finasteride: Avodart (dutasteride) is similar/in the same class of meds as Proscar (finasteride) which is the same medication as rogaine, (minoxidil) but at four times the dose. Avodart is relatively more potent, and so you can't consider adjusting the dose similarly. Avodart is not indicated for reversing hair loss, and because of its indications for the prostate, should not be taken by a 27 yo male. ...Read more
