Just received my package from tanresearch today.  A little background info about me:
 
I'm 29, male, 5'8", 140 lbs.  I had surgery on a hernia/testicle issue when I was in my teens, and immediately after, lost most of my libido.  Testosterone levels are really good, hormones are good, everything checks out.  Just sexual sensations are not so good.  Erections are not really a problem for me, it's the libido.  Figured I'd give this a shot since I'm soon out of my 20s and libido should be going down even further...
 
I thought I'd start off with .5 IU, since it's a small amount and from what I've read, low side effects.
 
15 minutes after...
 
I injected myself about 15 minutes ago and took a little bit of pepto bismol immediately after, just in case.  My injection site is red and ever-so-slightly itchy, and at first I thought I felt nausea, but I think it was from the excitement.  I am starting to feel a little bit of that flush (feels like being out in the sun, not a terrible feeling.)
 
I'll see how the effects are after I notice a change.  
 
(Might I add that the injection itself was surprisingly easy and painless?  I know I read that it was painless but it makes things that much easier for the next time.  )

Didn't notice any huge changes.  Can't report any 'all-night erections' as some other posters have, just normal ones.  Maybe I should try .75 or 1?

Right, I'm waiting it out, either 24 or 48 hours.

This last time, I felt a reaction, tho it was a small reaction.  Felt like normal erection pattern during the night; none of the 'raging hardons' that a lot of the other guys get.  Yesterday, though, it was as if I had a semi all day.  I left the gym with no underwear and noticed my pants looked a little obscene, to say the least.
 
No other reactions tho; no increased feelings of libido.  It seems like it works just like Cialis, but instead of taken orally, it's injected.  I'm not sure what the benefits are over Cialis just yet.  I guess it remains to be seen.
 
I just took .8 again. After this time, I will probably try 1.

^ Yup.  See original post.  My problem isn't really with ED but with libido.  I had read a few posts where some men mentioned increased libido, tho I thought that could just be their way of describing their ED.  Figured worth a shot.
 
I'm gonna finish my bottle, tho.  It's mild fun, but it's not really making a difference libido-wise.  Going to try for 1.1 next time.

One thing is a bit unclear with respect to this drug and that is does continuos dosing help increase one's libido as time goes by in a regimen or does the effect not build up cumulatively?

Somehow, for me, the time of day had an effect on how well Bremelanotide would work.  In the afternoon, coming in after mowing the lawn, didn't work.  In the morning, a little sleepy, it was awesome.  Early evening was good too.
 
I recently tried using a small amount in the morning on a regular basis.  0.25 mg, maybe 0.5 mg on a weekend day.  It didn't exactly hit my libido, but it was hitting more than just ED.  I certainly produced more precum and sensations were enhanced.  I was also using a daily-dose amount of cialis (5mg) and some Maca root.  The Maca root has worked for me in the libido department, and nicely when combined with horny goat weed.  (Get the Maca in bulk and take a couple teaspoons at night.)  Takes a few days, but nice when it works.
 
However, the Bremelanotide, and/or the whole combo, seemed to have diminishing effects over time.  I probably tried a bit more Bremelanotide, a little (but very little) weed, some alcohol, and I ended up with my blood pressure spiking (not in the 'get to a hospital' range, but it was time to lay down and be quiet for a while).  I had some other stuff going on, and my BP has been running a little high, so there may be more at work, but its a thought to take your BP mornings and evenings for a while before and during trying anything out.
