The applicable batch documentation should therefore identify the chemical form and whether the stated vial content is expressed as total acetate material or parent peptide equivalent.\n  \u003c\/span\u003e\n\u003c\/p\u003e\n\n\u003cp\u003e\n  \u003cspan style=\"color: #000000;\"\u003e\n    For the majority of routine analytical, investigative and general laboratory work, the Regular Larazotide Acetate specification remains highly suitable. The premium black-and-gold ULTIMATE Larazotide Acetate option provides an additional preparative high-performance liquid chromatography purification stage and a more stringent bacterial endotoxin and lipopolysaccharide testing specification for scientific projects requiring enhanced quality-control parameters.\n  \u003c\/span\u003e\n\u003c\/p\u003e\n\n\u003cp\u003e\n  \u003ca href=\"https:\/\/researchscientific.co.uk\/coa\/PEP034.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\n    View Certificate of Analysis\n  \u003c\/a\u003e\n\u003c\/p\u003e\n\n\u003cp\u003e\n  \u003ca href=\"https:\/\/researchscientific.co.uk\/msds\/PEP034.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\n    View Safety Data Sheet\n  \u003c\/a\u003e\n\u003c\/p\u003e","brand":"Research Scientific","offers":[{"title":"2mg","offer_id":50022206865746,"sku":"PEP034\/2mg","price":108.29,"currency_code":"GBP","in_stock":false},{"title":"5mg","offer_id":50022206898514,"sku":"PEP034\/5mg","price":253.8,"currency_code":"GBP","in_stock":true},{"title":"10mg","offer_id":50022206931282,"sku":"PEP034\/10mg","price":473.76,"currency_code":"GBP","in_stock":true},{"title":"20mg","offer_id":50022206964050,"sku":"PEP034\/20mg","price":879.84,"currency_code":"GBP","in_stock":true},{"title":"50mg","offer_id":50022206996818,"sku":"PEP034\/50mg","price":2030.4,"currency_code":"GBP","in_stock":true},{"title":"5 x 5mg Lab Pack 1","offer_id":51243458396498,"sku":"PEP034 \/5mg x 5 Lab Pack","price":1057.5,"currency_code":"GBP","in_stock":true},{"title":"10 x 5mg Lab Pack 2","offer_id":51243459445074,"sku":"PEP034 \/5mg x 10 Lab Pack","price":2115.0,"currency_code":"GBP","in_stock":true},{"title":"5 x 10mg Lab Pack 3","offer_id":51243459674450,"sku":"PEP034 \/10mg x 5 Lab Pack","price":1974.0,"currency_code":"GBP","in_stock":true},{"title":"10 x 10mg Lab Pack 4","offer_id":51243460034898,"sku":"PEP034 \/10mg x 10 Lab Pack","price":3948.0,"currency_code":"GBP","in_stock":true},{"title":"5mg - Ultimate","offer_id":54656970752338,"sku":"PEP034U\/5mg","price":368.01,"currency_code":"GBP","in_stock":true},{"title":"10mg - Ultimate","offer_id":54656970785106,"sku":"PEP034U\/10mg","price":686.95,"currency_code":"GBP","in_stock":true},{"title":"20mg - Ultimate","offer_id":54656970817874,"sku":"PEP034U\/20mg","price":1275.77,"currency_code":"GBP","in_stock":true},{"title":"50mg - Ultimate","offer_id":54656970850642,"sku":"PEP034U\/50mg","price":2944.08,"currency_code":"GBP","in_stock":true},{"title":"5 x 5mg Lab Pack 5 - Ultimate","offer_id":54656970883410,"sku":"PEP034U\/5mg x 5 Lab Pack","price":1533.38,"currency_code":"GBP","in_stock":true},{"title":"10 x 5mg Lab Pack 6 - Ultimate","offer_id":54656970916178,"sku":"PEP034U\/5mg x 10 Lab Pack","price":3066.75,"currency_code":"GBP","in_stock":true},{"title":"10 x 10mg Lab Pack 8 - Ultimate","offer_id":54656970948946,"sku":"PEP034U\/10mg x 5 Lab Pack","price":2862.3,"currency_code":"GBP","in_stock":true},{"title":"5 x 10mg Lab Pack 7 - Ultimate","offer_id":54656970981714,"sku":"PEP034U\/10mg x 10 Lab Pack","price":5724.6,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/9769\/7362\/files\/nupex-larazotide-acetate-research-peptide-ultra-pure-powder.png?v=1767865921","url":"https:\/\/nupex.co.uk\/products\/larazotide-acetate-research-peptide","provider":"Nupex","version":"1.0","type":"link"}
