What are the side effects of bremelanotide? The factsheet by Palatin (the makers of Pt-141) says they "include facial flushing, nausea, aftertaste and post-nasal drip". Headaches also get mentioned, particularly in women.

Chemgasm describes the flushing like this:

At 20 minutes post-dose, it peaked. Face had flushed scarlet red, my chest was somewhat red too, little pricks of red (allergy-like) appeared on my arms and chest and face. I experienced that hot-from-the-inside feeling one gets the night after being in the sun all day. Over the next ten-twenty minutes, the flush subsided.

All this might not sound so bad compared to, say, Viagra's "priapism, severe hypotension, myocardial infarction, ventricular arrhythmias, sudden death, stroke and increased intraocular pressure".

But remember that it's early days yet, and more side-effects are going to be coming out of the woodwork pretty soon.

Now, it's time to meet the enthusiasts. Let's go on a quick tour of the people who are already using Bremelanotide, or who are dreaming of it.

First stop is social network site Tribe, where the aphrodisiacs group are more than a little sceptical of the sites claiming to sell Bremelanotide.

The forums over a melanotan.org have been buzzing about the power of PT-141 for a good six months now. Several of them have been actively experimenting with the drug, and they're pretty positive about it.

If you want to know what blogs are talking about bremelanotide, you could do worse than searching Technorati. You'll find a lot of dross, but you'll also run into gems like Menz News, a blog which is actually (for once) trying to provide serious, honest information about using "science for better sex". Heartily recommended. He already has a couple of posts on PT-141, including a financial analyst's report on it.

Note: this is probably as good a time as any to make it very clear that I'm not a doctor, and I can't say what bad things trying Bremelanotide could do to you. I'm certainly not advising anybody to try it before the end of the clinical trials.
