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

Just to correct myself from the original post. I had run 2 vials of primo and started on the 3rd - my apologies for the mistype
