I'm far from an expert but their gh and peps are what I'm least sus of. I was running 5ui ed for like 3-4 months without doing enough research and at the end I was experiencing pretty much every sign of too much gh. Super high bp and cholesterol, carpel tunnel in hands and starting in feet, thyroid more than double the normal range etc etc. I stopped it and 4 weeks later all my shit was back to good so I feel like it's what it says it is and I know for a fact the bpc is at least real as well as semaglutide and sema seems to be dosed correctly because both the people I've gotten it for said they experienced exact same sides as pharma grade they were taking before. The test cyp 250 though..... I was taking 750mg per week for months, developed severe acne on back and not a severe other places and then labs came back at only 1699. Switched to Ultima AND lowered dose to 350mg pw and 4 weeks later my shit was 2797! So about 3xs more potent! So got me real hesitant use these bottles of deca, win, npp......
