Second batch of MTS test e 300 pins way smoother than my first, anyone tracking batch to batch?

Just cracked open my second order of MTS test e 300 and the difference in the pin is night and day, first batch had a bit of a sting to it and these new vials go in like water. Nothing else changed, same delt, same 25g, so its got to be the brew itself. Got me wondering how many of you actually track this stuff batch to batch or whether im overthinking a bit of pip. I know the smoothness mostly comes down to the carrier oil and the BA content rather than the actual dose, and MTS have always been solid on dosing for me, bloods climbed exactly where id expect last run. Anyone else compare their vials order to order or do you just pin and get on with it?

Smoother pin batch to batch is nearly always the carrier and the BB/BA ratio, not the actual dose. A batch with a touch less BA in it will sting a lot less while pinning the exact same mg. The only honest way to know a batch is legit is bloods, MTS run the test e correctly dosed and usually a bit over so your numbers should climb reliable regardless of how it feels going in. Filtration plays into it too, a proper 0.22 micron job runs clearer and cleaner than a coarse filter. Id not read too much into one batch feeling nicer, get bloods at the same mg per week on both and youll see the dose is consistent even when one stung more.

Good to see this discussed properly. Every batch goes through the same 0.22 micron filtration and the raws get tested, so if one pins a touch smoother its the solvent ratio not the dose. Bloods will show you the test lands the same either way. Appreciate you lads keeping it honest.

Good thread. The honest way to compare batches is bloods at the same mg per week. Pin feel comes down to the solvent ratio and BA content, not the dose, so any smoothness difference you're seeing is the carrier oil rather than potency. Test e has held up well through the supply squeeze.

Second batch pinning smoother almost always comes down to the solvent ratio not the dose, a touch less BA in the mix and it stings less going in. The only real proof a batch is legit is bloods, if your total test climbs the same on both then the dose is consistent even if one stung more. MTS runs correctly dosed and often a bit over so I wouldnt read too much into how a pin feels. If you want to track it properly just log your mg per week and your numbers each panel, thats the honest comparison batch to batch.

Smoother pin does not mean a stronger or weaker batch, that is all down to the carrier oil and how much BA is in it, a gentler solvent ratio just stings less going in. The only thing that actually tells you a batch is legit is bloods at the same mg per week, if your total test climbs the same on both then the dose is consistent even if one pinned rougher. MTS has always run correctly dosed and often a touch over, so I would not read too much into how the second lot feels. Clarity in the vial is a rough proxy for a proper fine filter but that is about as far as feel gets you.
