this is not the only problem I had with this batch.... curious to see @Primal_Pharma response.
either way i think im going to bin all this test don't want to risk it....

It's Test P 200mg?

That’s just the game we play with high concentration gear brother

That's not necessarily the case

It depends whether one specific ester is pushing it's solubility limit
You could have a 1,400mg/mL blend of Test D 500 + EQ 500 + Tren E 200 + Mast E 200 and it theoretically would give no PIP worse than any of the individual compounds alone.

For instance, the WWB/GGB Test 600 blend has fucking 180mg/mL Test Ace and that cripples me.

But JY Pharma Test 600 = 300 E/C, and it's perfectly smooth.

Thread 'Mythbusters #1: High Dose Blends: PIP + Solubility'

Welcome to the "Mythbusters" Series: Discussing common misconceptions/folklore about AAS!

---

In this first edition, we're tackling high-concentration steroid blends and the infamous PIP. We will cover:

• How solubility and crystallization actually work.
• Why a well-formulated blend isn't the problem.
• What really causes high-dose blends to "crash" in the muscle.

---

One of the biggest myths in this space is that high-dose blends are inherently more painful than their individual components.
This is fundamentally incorrect. Let's...

What problems are you having? I have MCT test C from a source on a different board i havent gotten into yet, and its slightly yellow. Only other MCT test c I have had was Stans and his is clear as day.

Glad to see you're dropping the concentrations on the top 2 compounds with the highest solvent content.

Absolutely. It improves stability and it's just better all around.

Way to go guys. That is teamwork that benefits the community. Nice to see everyone get a win in the end.

let's just say inspect your vials maybe with a flashlight

Any reason not to disclose the details? Sounds like information the community would benefit from.

I will do once home later tonight and report back, curious now… because I didn’t see anything when I first got them. Bought two 100ml vials so would suck if stuff shows up under flashlight.

ordered some TC250 a few weeks back . vials arrived with particles floating in them. primal resent and those vials too had fibers floating in them.

If youre talking about S** then im pretty sure thats normal for larger vials. My 50ml test c was like that too, slightly yellow.

TC250

Trashing it seems like a waste, I'm sure someone would take it off your hands for more than $0...

That's concerning

 

[anabullic]

That's concerning

i was informed it was from overused filters and that it has been rectified. have been keeping eye out to see if anyone had similar experience

Chem's right. No sense in binning it when you could make a buck or two @anabullic

yea probably just could use some filtering and itll be g2g

 

[anabullic]

you guys right times like this we aint trashing shit where's that espresso tren im buying it lol

 

[readalot]

For the light source, we use a 450nm blue LED inspection lamp. Every vial is checked under it.

Comments @Primal_Pharma? I was really impressed when you mentioned every vial was getting checked before release and your team was being very careful with filter life IIRC?

 

[readalot]

We typically limit each filter to around 3,000–4,000mL, depending on the viscosity of the compound and carrier oil. Higher viscosity brews (like DHB or higher concentration esters) are filtered in smaller increments or with more frequent filter changes to avoid over-pressuring the membrane.

This was a one-off with one filter run for too long? Any root cause analysis to ensure you eliminate floaters for future batches?

 

[Jonboy]

Here is my stock when it first came in. It was over a couple or maybe 3 orders. Everything is nice and clear. Except the deca and NPP is a tad bit yellowish. Also here is my current stock now. I actually used this vial of yellow Test Cyp 250. I was told it just oxidized differently than the others. Idk? Opinions?

 

[BigDadd7]

That's not as yellow as I thought it would be
