Originally marketed by ErgoPharm, 6-OXO became widely known among performance supplement enthusiasts, bodybuilding forum users, and collectors of discontinued sports nutrition products. The product stood out for its focused single-ingredient formula, bold bottle design, and strong association with the hormone-support category of the early prohormone market.\u003c\/p\u003e\n\u003cp\u003eThis archive page is provided for historical and informational reference only. ErgoPharm 6-OXO is no longer available for purchase and is listed as out of stock\/discontinued. The information below reflects historical product details, label-style information, ingredient naming, and the role 6-OXO played in the old-school supplement landscape.\u003c\/p\u003e\n\u003cp\u003eThe original ErgoPharm 6-OXO formula featured 6-OXO, listed as delta-4-10,13-dimethylcyclopenta[a]phenanthrene-3,6,17-trione. The historical label information identified the amount of active substance in one serving of 3 capsules as 300 mg of 6-OXO. The product was commonly packaged in a 60-capsule bottle and became one of the best-known standalone products associated with post-cycle support and hormone-modulating supplement discussions from that era.\u003c\/p\u003e\n\u003cp\u003eUnlike many prohormone-era formulas that relied on multi-compound blends or broad proprietary formulas, ErgoPharm 6-OXO was built around one featured active ingredient. That simple and direct presentation made the product easy to identify, easy to discuss, and memorable within the discontinued bodybuilding supplement category. Today, 6-OXO remains a commonly searched legacy product name among users researching old-school prohormones, discontinued ErgoPharm products, and the history of performance supplementation.\u003c\/p\u003e\n\u003ch2\u003eProduct Status\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e Discontinued \/ Out of Stock\u003cbr\u003e\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Historical bodybuilding supplement archive\u003cbr\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ErgoPharm \/ Ergopharm\u003cbr\u003e\u003cstrong\u003eProduct Name:\u003c\/strong\u003e 6-OXO\u003cbr\u003e\u003cstrong\u003eFull Ingredient Name:\u003c\/strong\u003e delta-4-10,13-dimethylcyclopenta[a]phenanthrene-3,6,17-trione\u003cbr\u003e\u003cstrong\u003eBottle Size:\u003c\/strong\u003e 60 capsules\u003cbr\u003e\u003cstrong\u003eHistorical Serving Size:\u003c\/strong\u003e 3 capsules\u003cbr\u003e\u003cstrong\u003eHistorical Label Strength:\u003c\/strong\u003e 300 mg per 3-capsule serving\u003c\/p\u003e\n\u003cp\u003eThis product is not currently available for purchase.

During the early 2000s, 6-OXO became one of the most discussed ingredients in the hormone-support side of the sports nutrition market.\u003c\/p\u003e\n\u003cp\u003eThe ingredient was commonly associated with aromatase-inhibitor-style supplement positioning during the old-school prohormone era. In that market, products were often separated into several major categories: direct prohormone products, support products, post-cycle products, and formulas intended to complement the use of hormone-related bodybuilding supplements. ErgoPharm 6-OXO became strongly associated with the support side of that category.\u003c\/p\u003e\n\u003cp\u003eOne reason 6-OXO became memorable was its focused formula presentation. The label centered on one active ingredient rather than a long proprietary blend. This made the product visually and conceptually distinct from many other performance supplements of the same period. Its single-ingredient identity also helped it become a frequent topic in archived bodybuilding forums, supplement review discussions, and historical product databases.\u003c\/p\u003e\n\u003ch2\u003eHistorical Context\u003c\/h2\u003e\n\u003cp\u003eErgoPharm 6-OXO was released during a period when prohormones and hormone-related sports supplements were some of the most discussed products in the bodybuilding market. During this era, brands often created products around compounds associated with androgenic pathways, estrogen management, post-cycle support, and performance-oriented body composition goals.\u003c\/p\u003e\n\u003cp\u003eErgoPharm was one of the more influential brands in that space. Products such as 1-AD and 6-OXO helped establish ErgoPharm as a major name in the early prohormone and hormone-support supplement market. While 1-AD became closely associated with the prohormone side of the category, 6-OXO became one of the best-known products connected to the aromatase-inhibitor and post-cycle-support conversation.\u003c\/p\u003e\n\u003cp\u003eToday, 6-OXO is primarily remembered as a discontinued legacy product. It is often searched by users looking for information about old-school bodybuilding supplements, discontinued prohormone-era products, and the original ErgoPharm product lineup.\u003c\/p\u003e\n\u003ch2\u003eWhy ErgoPharm 6-OXO Became Well Known\u003c\/h2\u003e\n\u003cp\u003eErgoPharm 6-OXO became well known because it occupied a very specific place in the early-2000s supplement market. While many products from that era focused directly on prohormone compounds, 6-OXO became associated with the support and hormone-modulation side of bodybuilding supplementation.\u003c\/p\u003e\n\u003cp\u003eThe product’s simple formula helped reinforce its identity. Rather than being marketed as a large blend of multiple ingredients, 6-OXO was presented around one featured compound. This made it easy for users to recognize and remember. The name “6-OXO” itself also became a highly searchable legacy term within old-school bodybuilding supplement discussions.\u003c\/p\u003e\n\u003cp\u003eThe bottle design was also part of its legacy. Classic ErgoPharm packaging used strong color contrast, bold typography, and a straightforward scientific presentation. This gave the product a distinct look that matched the early 2000s performance supplement era and helped it stand out visually from more generic bodybuilding products.\u003c\/p\u003e\n\u003ch2\u003e6-OXO and the Old-School Prohormone Era\u003c\/h2\u003e\n\u003cp\u003eThe old-school prohormone era was defined by aggressive product innovation, compound-specific marketing, and intense discussion across bodybuilding forums and supplement communities. During this period, products were often evaluated based on their listed actives, perceived potency, label transparency, and brand reputation.\u003c\/p\u003e\n\u003cp\u003eErgoPharm 6-OXO fit into that environment as a specialized support product. While it was not positioned the same way as direct prohormone products such as 1-AD, it became closely connected to the broader category because of its association with hormone-support discussions. This relationship is one reason 6-OXO remains relevant in historical searches related to prohormones, post-cycle support, and discontinued bodybuilding supplements.\u003c\/p\u003e\n\u003cp\u003eFor collectors and supplement historians, 6-OXO represents a specific chapter in the evolution of sports nutrition. It reflects a time when single-compound formulas, science-heavy label language, and forum-driven product reputation played a major role in the success of bodybuilding supplements.\u003c\/p\u003e\n\u003ch2\u003eOut of Stock Notice\u003c\/h2\u003e\n\u003cp\u003eErgoPharm 6-OXO is no longer available for sale.
