O.P.M.S. (Optimized Plant Mediated Solutions) is a veteran in the kratom industry and a name you’ve likely seen in smoke shops and convenience stores. But is its long-standing presence a sign of consistent quality—or just good marketing?
We took a deep dive into the brand’s history, reputation, and product lineup to bring you an honest, no-hype review. Below, we break down everything you need to know about O.P.M.S., including its pros, cons, and top alternatives.
O.P.M.S. has been around since 2005, making it one of the first kratom brands to break into the U.S. market. While it gained initial popularity through headshops, the company expanded into online sales by 2009. Today, O.P.M.S. is widely recognized and often featured in retail displays at physical stores nationwide.
Though there are two prominent O.P.M.S. websites—OPMSKratom.com and BuyOPMS.com—it’s unclear if both are officially run by the brand itself. Either way, non-wholesale customers can purchase O.P.M.S. products online through various third-party retailers.
Notably, O.P.M.S. is one of the early adopters of the American Kratom Association’s GMP (Good Manufacturing Practices) program, which promotes safer manufacturing standards and third-party lab audits. That said, transparency around testing remains somewhat limited.
Product Selection: What Does O.P.M.S. Offer?
O.P.M.S. keeps its kratom selection relatively narrow but focuses on highly concentrated extracts. Its current product lines include:
• O.P.M.S. Black (strongest extract line)
• O.P.M.S. Gold Capsules
• O.P.M.S. Liquid Shots
• O.P.M.S. Silver Capsules and Powder
Popular strains include Maeng Da, Malay, and Silver Thai, though you won’t find the wide strain variety offered by vendors like Golden Monk or New Dawn Kratom. Still, the O.P.M.S. extract line is favored by those seeking potent, fast-acting effects.
Pricing for O.P.M.S. varies depending on the retailer. Fortunately, the brand publishes suggested retail pricing online:
• Liquid Extracts: $16.95–$17.99 per shot
• Kratom Powder (1 oz): ~$7.19 to $8.49
• Capsules: Prices depend on strain and size
While these prices are competitive compared to many headshop vendors, they’re often higher than bulk kratom suppliers online. For example, Amazing Botanicals sells 30g of powder for just $5.99, while Kratom Bloom offers 1,000g for $79.95.
Before purchasing, always check what payment methods are accepted by the seller—some accept credit cards, while others may require cryptocurrency.
Reactions to O.P.M.S. are deeply divided, especially on platforms like Reddit. Some users swear by the potency of its extracts, while others express serious concerns:
Negative feedback includes:
• “Did nothing for me.”
• “I regret ever using O.P.M.S. Black… I’ve spent thousands and feel like a shell of myself.”
• “Results are inconsistent. Sometimes it feels like something other than kratom.”
Positive feedback includes:
• Users who prefer O.P.M.S. over other headshop options
• Strong praise for O.P.M.S. Liquid and Black extract lines
Despite some praise, recurring issues include high prices, product inconsistency, and lack of detailed lab testing transparency.
O.P.M.S. has history and name recognition on its side, but that doesn’t necessarily make it the best option. While its extracts are among the most potent on the market, prices are steep, and feedback on quality is mixed.
If you’re loyal to headshop kratom or seeking a strong extract, O.P.M.S. might suit you. But if you’re looking for better value, more variety, and clearer lab results, other GMP-certified vendors like MIT45 or Golden Monk are worth your attention.
