Question Please help, what am I doing wrong? The reaction does not work

[Pajmon]

I would need some advice. I'm already desperate. Some time ago, I reacted normally and it was always good as a result. Then I didn't do it for a while and when I came back the results are very bad and I don't know what I'm doing wrong. I'm using Nurofen Stop Grip. The pesudeoephedrine I get is white, it probably won't be a problem. I cook in an oil bath and use a ratio of pseudo-1g/0.5g phosphorus/1g iodine and 0.4ml H3po4. I heat the pseudo phosphorus and H3PO4 to a temperature of 110C, then I start throwing in the iodine, which I divide into 10 equal parts and throw in every two minutes. I finish after 20 minutes at a temperature of 130C. then I hold the reaction for another 20-30 minutes at a temperature of 130C, the reaction happens there, the bubbles are there. Everything looks like before, but the result is weak and the smell is different. I tried replacing the chemicals with new ones.. It didn't help, I tried a different ratio of substances, it didn't help either. I've been struggling with this for a long time, so if anyone can advise me I'll be very grateful

Looking at nurofen stop-grip, it has both enantiomers of pseudoephedrine in it, 1R,2R and 1S,2S, so you are making racemic meth. I've never heard of such a thing, and I don't kmnow if that is new or it's aleways been that way. 1R,2R is referred to as psuephedrine (not a typo) and isn't used to make meth because it makes that weak kind

I'm sure it had to change because before that Nurofen was the best. Thank you very much for the advice. Do you know how Paralen Stop grip is? Modafen is also sold but I can't get it out of it.
