High e2 on recent UPA primo batch? was created by SORN
Hi Everyone,
Has anyone had any issues with a recent batch of UPA primo?
Had been running 300T 300P for the last 3 months of last year. Im a high aromatizer 1:1 works for me, E2 is in range.
I grabbed a final vial from a well trusted source(same ive used for the last 3) - the sticker on it, which im assuming hopefully indicates a batch reads
UPA-224I
Exp: 09-2029
8 days into this vial, skin broke out, nips got spicy and by day 12 I was carrying a bunch extra water. Switched over to eq for now but im wondering if anyone else has had issues recently?

In range confirmed with blood work?
8 days seems a little short as it will usually take about 30 day for a decent rise in blood plasma levels, so suddenly jumping to eq might be a false start. And eq to test 1:1 is going to crash your e2, ive got guys currently who have crashed e2 from equi.

Would be interesting if the new batches of primo and masteron in SA could have been tested.

8 days into the 3rd vial of primo so we talking around 2 months on the same cycle, issues only started on the last vial of primo which is a different batch. EQ is not 1:1 I've switched because the last vial of primo gave me spicey nips and water retention. Primo doesn't do that.
My question is specifically if anyone else has had issues with a recent batch/this batch.

I will make arrangements to send this vial off to Janoshik later in the year - January long.

My assumption is that UPA possibly got a crappy batch of raws. I know a lot of people use primo for e2 control, its fairly useless at that for me, but for anyone who it does work as an AI for, they will find that it may make their situation worse if its from this batch

Hi
I was actually on these forums to figure out what I’m going to do because I had the same experience. A ton of water in a very short timeframe. I suspected it was deca and not primobolan.
batch number UPA-225l
Did you test these vials? Is UPA usually good quality?

Just a thought, when you lower SHBG you increase free testosterone which then can aromatize higher on your base dose of testosterone you currently running with it.. It does NOT block estrogen and it doesn't inhibit aromatase or compete at the ER, so in theory you could indirectly get gynecomastia sides from legit primo... The old data around primo was DHT competes with estrogen at the tissue level, reducing some estrogen effects but not reducing estrogen, it also doesn't aromatize and then having a higher androgen to estrogen ratio reduces some estrogen symptoms. The old literature was sometimes worced wrong, but it certainly doesn't act like tamoxifen, aromasin, clomid, letro etc..
