Doesn't make sense OK - speaking as a chemist....2,4-dinitrophenol is 2,4-dinitrophenol. 1 g of DNP is a gram of DNP. What is this "crystal can be 5x stronger"? That's like saying I'll get more water from 100g of ice than 100g of liquid water. The *only* way that can be true is if the...

Well, they were a board sponsor at a couple of locations - had a good reputation initially, but have apparently gone bad since August :( Oh well, the good initial results mean that they got some of my money - I'll survive, I suppose. These things happen sometimes.

Lutalyse (PGF-2a) (Prostaglandin-like Growth Factor -type 2 alpha) I've tried it - the chemist in me was curious... 1) Used intramuscularly, it *essentially* triggers the chemical effect of exercise - in *theory* you could just site inject it and it would be as though you trained that muscle...

I know, have to be careful. But has anyone dealt with them? anyone?

Just wondering if anyone has dealt with this research chem supplier (substitute for the *, obviously) Opinions? Doctor9

As someone with an actual scientific degree - I will agree with all of the above - *except* the extrapolations at the end with respect to where the material is going. Cocaine is still (as far as I know) the anesthetic of choice for nasal surgery - the side effect of constricting the blood...

One quick comment, the Twilight series and Harry Potter are not even close to being in the same boat. Twilight is a gussied-up Harlequin romance with a vampire/werewolf twist. Harry Potter - well, you'd have to read the books. The earlier ones are more simplistic, but as the series goes on...

Follow-up on formulation variation Well, *technically* I should have done this one variable at a time, however, what's done is done. The good news is: The new prop formulation (see above) is *wonderful* no initial or delayed-onset pain so far (2 days of use at this point - will be doing 3rd...

Just in case anyone is interested... I just finished preparing a trial version based on my ideas above. Did not use MCT oil (didn't have any on hand) but did find out that peanut oil is absorbed more slowly than grapeseed oil, so: 50/50 GSO/Peanut Oil 2% BA, 2%BB (kept some in to maintain the...

Well - a one-person test would be easy - prepare prop using the standard formulation and the idea I had - try them on the same person, and see what happens. I may do just that, as I am currently experiencing prop pain myself - Homebrewed, but I'm a chemist, I know a thing or two about sterile...

Prop Pain workaround???? Now, if the above is taken as true, in conjunction with the statement that too much BB is also leading to the pain, does anyone see a logical flaw with the following: 1) Prepare test prop in an oil/BA mixture only (2-2.5% BA), *no* BB. 2) Use a oil, or oil mixture...

Minor correction :) Not to contradict anyone, but the dissolved powder accounts for some *volume*. Weight isn't the issue here, the volume is. If you dissolve something in a solvent, it takes up space - not always the amount expected, mind you - as an example - 50mL of water plus 50mL of...

The chemist speaks: For applications where Peg 300 was specified - Peg 400 should be fine - the viscosity difference is not significant. I'm not sure about Peg 600, though - if a formulation is calling for it, it's almost certainly because the particle density is such that it falls out of...

New to the board - but a chemist in real life - so let me add my $0.02 I would say that peristaltic pumps are almost *ideally* suited to this sort of work - any pump that relies on an air pressure differential - in my filtration experience - is at a distinct disadvantage with more viscous...
