The Whale, is, appropriately, Reta lol

The BPC - BPC/TB kind of unfairly diluted the vote though. If it was just one I think BPC would've won easily.

Fatties v. Cripples

You must be joking lol
Our pricing are always the cheapest.
Each time I made a promo for reta or tirz, it’s the cheapest ever done, other competitors they try to follow later by dropping a $5 from my pricing, i remember when I made the tirz 50mg $400/kit us domestic free shipping which was almost 50% off market price, I was contacted by a seller who told me don’t you plan to stop that price dropping?
At this point I can’t even remember when was the last time I updated reta pricing, the one I keep changing is the promo ones.
Doubt that? Np
You’ll see monday lol

Fml. I’m already stretched thin from the raw shortages…..

How is 40 cents per filter expensive? I want to see this much cheaper alternative!

You didn't understand my message my friend I said His link was expensive 85 euro for 100pcs.

Yours and mine are cheaper

Just don't get the one with the .65 prefilter. We don't need it for our purposes, and it will cost you some peptide.

The recent batches are exactly 10ml. I know since I refiltered my QSC oils today. From a 20ml syringe, through a 0.22um filter, a 23G needle, into a 20ml vial. Hard work (yes, I did use a venting needle, still). But the filtered oil looks beautifully clear.

Buy a caulk gun. Your hand will thank you.

How can you tell you've blown a syringe filter? Does the back pressure just suddenly let up, or does the case break before the filter does (I hope)?

The pressure in the plunger drops significantly. Caulking guns suck honestly. The weighted jigs that keep a constant pressure on the plunger are the way to go some people have made some out of wood and posted pictures on meso. The beauty of those is you can set it and forget it and walk away the caulking guns need constant babysitting

In my experience the syringe break before the filter and even if it doesn't blow and you blow the filter it goes from: this is fucking. Slow to... Ups it's flowing like water.

But I have to say after having tried the caulk gun I believe 10ml/5ml syringe could be faster. I have to retest it back to back but last time I was filtering 20/30ml of carrier oil with a 5ml syringe and it was quick as fuck.

I had a 3ml syringe that wasn't moving, then suddenly "gave"after pressing hard enough (still some pressure). Just wondering how I would know for sure I broke the filer, as there wasn't any other sign. With PES, if there's an air bubble, it apparently takes a lot to push it through so I assumed it was that,

The blowouts on those typically happen around the edge almost impossible to see. Something that may help and we use it on filtering cannabinoids in an ethanol solution is to pull a vacuum on the receiving flask and have head pressure on the feedstock. Did you pull a vacuum on the receiving vile? That can usually help as well. At least to get it started It's better to do that than to simply throw a needle in the receiving vial to aspirate to atmosphere

Should be super easy to filter with 3ml syringe. Like 20/30 seconds max. Strange

from my experience, it usually breaks at the luer lock joint where filter attaches to syringe, i just snapped one yesterday refiltering some q oil , it was at the end of the filtering process so i didn't make a mess , i usually filter 40 ml per syringe filter as to not overload the filter

Anyone get primo 100 in the promo? I emailed the rep and I am waiting for a reply. According to the skus the red tops are the primo but I noticed a couple of vials crashed which makes me think it may be the cyp and the primo 100 may be the green tops. I think the grey tops are the sustanon.

i use a 20 ml syringe and it seems to work pretty darn good ,

It usually is. Only "stopped" completely a couple of times, which is why I think it was a bubble.

Well these are tiny amounts, 1-3ml of reconstituted peptide, and the pressures I'm talking about were no where near breaking point of the 3ml syringe, just suddenly impossible to push without a "shove". I just don't know how "fragile" the syringe filters are. With breaking luer lock joins and exploding syringes, I assume much tougher than I imagine.
