I remember it was only recently that a large number of SST US dom vendors were caught with floaters. Earlier this month I think, or was it last month. Either way they still treated that batch as having no issues and continued selling it, honestly no different from Chinese vendors.

most of SST is just chinese resellers
theyve shown testing of their oils that are overdosed the same amounts as ive seen from specific chinese sources
its also heavily censored im sure you know

First time dealing with this company. Got a price list on monday and asked if mast e was in stock and was told itd he in Wednesday. Ordered a kit and some aromasin. Also ordered some test d raws from another source just so id have a good amount of TRT to survive what appears to be an impending extension of a drought. Gonna send a sample of both out to jano when they show up and ill post the mast e here. Hopefully its all good, love me some mast

I kit of Mast E would be lovely. I'm too broke at the moment though dang lol.

 

[Mastedon]

What kind of filters do you use.

I think sterile PES hydrophilic 0.22um pore, 33mm membrane but I'm sure others will chime in

What kind of filters do you use. I normally source all my test domestically and never use a filter. It seems the general consensus here is that all Chinese oils ought to be filtered. I happen to order 20 bottles of cyp through SSA before they went away and just ordered 10 Test C and 10 Test E through GGB thinking my order from SSA wasn't going to arrive because tracking never changed from shipping label created. Then of course the it shows up right after I place a decent order here lol

1 filter allows you to filter ~100ml.

All UGL injectables should be filtered. Chinese or domestic. Visible contaminants or not

 

[Mastedon]

Are the ones I have ok for peptides?
Then use the ones you shared for oils?

Yes but for peptides, in general u don't want 33mm because there's quite of wastage as stuff is left behind in the filter. I see @Ghoul here, I'm sure he can link you better ones..

For carnitine, glutathione, etc urs is fine.

Well I guess I probably should have known that. Lol now that I'm about 2000 ml of oil deep probably a good time to start. I suppose I ought to be filtering my GH as well? Any recommendations on the appropriate filter for that?

What's your test d source

 

[trismegistus]

What's your test d source

Its not kosher to post another source in a sources thread, being as they sell peptide products also

 

[didleyr6]

Any NZ/AU buyers from this vendor? Not a whole lot of guys willing to ship here….

 

[Liter O' Test]

are these guys takingorders

 

[BigDadd7]

are these guys takingorders

I sent an email several days ago and never heard back. They're either down, or just too busy. Not worth tracking them down and hoping for a good experience right now.

Might also have to do with the chinese holiday starting tomorrow. No sense accepting orders if they wont ship until after the 8th, plus another source said itd be safer to wait until after since customs gets tight right before and during the holiday. I had the option to have them send it anyway but they wouldn't do a reship if it was seized if I did
