{"title":"PCT Blends","description":"\u003cp\u003ePCT blends, also listed as post-cycle therapy blends, post-cycle support or PCT capsules, are multi-ingredient products sold under a product name rather than the name of a single established compound. This page lists every PCT blend stocked at Free Muscle, compared on stated ingredients, capsules per pack and whether the batch has been assayed by an independent laboratory. We do not give cycle, protocol or post-cycle advice of any kind. These products are supplied for laboratory research to adults only.\u003c\/p\u003e\n\n\u003ch2\u003eWhat is a PCT blend?\u003c\/h2\u003e\n\u003cp\u003ePost-cycle therapy is a term from bodybuilding forums rather than from clinical medicine. It refers to the notion, discussed on those forums, of products used after a course of hormonally suppressive compounds. A PCT blend is a capsule or tablet that combines several ingredients under one label aimed at that market. Because there is no single molecule called PCT, there is no pharmacology of PCT, no receptor for it, no development history and no trial data on any blend as a product. Each blend is only the sum of what is in the capsule, which is a question for the label and the batch certificate.\u003c\/p\u003e\n\u003cp\u003eAcross the market, products sold under the PCT label draw from a few ingredient categories. Some contain prescription-class molecules such as selective oestrogen receptor modulators or aromatase inhibitors. Some contain botanical extracts, vitamins and minerals of the kind found in products marketed as testosterone boosters. Some contain both. Which of these a specific product contains, and in what quantity, is stated on its label and confirmed only by the certificate of analysis for that batch. For our own blend, what the capsules contain is set out on the label and confirmed by the batch certificate, and we make no claim about what it does.\u003c\/p\u003e\n\u003cp\u003eNo PCT blend is a licensed medicine in the UK or EU. Where a blend contains a SERM or an aromatase inhibitor, that ingredient is a prescription-only medicine when sold as such, and the blend is not authorised as a food supplement either. Suppressed hormone production is a medical condition that is diagnosed with blood tests and managed by a clinician.\u003c\/p\u003e\n\n\u003ch2\u003eWhat the published research reports\u003c\/h2\u003e\n\u003cp\u003eThere are no clinical trials on any PCT blend as a product. The closest published evidence looks at the ingredients such blends draw from, at the drugs used as post-cycle therapy, and at what products sold under the name actually contain.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnalysis of online testosterone-boosting supplements (2019).\u003c\/strong\u003e Researchers traced the 19 unique ingredients of the five best-selling testosterone-boosting supplements on a major online retailer through 191 published studies. Of the 37 human studies, about 30 per cent reported an increase in testosterone and about 46 per cent reported no effect. Once suspicious customer reviews were filtered out, reported benefits fell sharply. Balasubramanian A, et al. Testosterone Imposters: An Analysis of Popular Online Testosterone Boosting Supplements.

Ninety per cent claimed to boost testosterone, but only about a quarter of the ingredients had any supporting data, and about 10 per cent of components had published evidence of a potentially negative effect on testosterone. Several products exceeded the tolerable upper intake for certain vitamins and minerals. Clemesha CG, et al.

Both recovered after about three months, and the authors concluded that the SARMs, the post-cycle substances or both may cause such injury. Koller T, et al.

Where a blend contains a prescription-class molecule such as a SERM, the trial data for that molecule exists only in medically monitored patients, and is discussed on the relevant compound page, for example \u003ca href=\"\/en-ro\/collections\/enclomiphene\"\u003eenclomiphene\u003c\/a\u003e. None of the above is a claim about any product on this page.\u003c\/p\u003e\n\n\u003ch2\u003eBrands of PCT blend we stock\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Muscle PCT, Post Cycle Therapy, 60 capsules.\u003c\/strong\u003e Our own brand blend, 60 capsules per pack, in capsule form.

Start with the ingredient list and ask, for each ingredient, what it is and how many milligrams of it a pack contains: strength per capsule multiplied by capsules per pack. Then set that against the price for a cost per milligram of each named ingredient, and ignore proprietary blend totals that do not break out the individual amounts. Finally, check the batch certificate: a certificate for a multi-ingredient product should identify and quantify each listed ingredient, not just report a single purity figure.\u003c\/p\u003e\n\n\u003ch2\u003eBatch testing and certificates of analysis\u003c\/h2\u003e\n\u003cp\u003eA certificate of analysis (COA) reports what an independent laboratory found when it tested a sample from a specific batch. For a blend, that means the identity of each named ingredient and the measured amount of each, together with the laboratory name, method, batch number and date. Every Free Muscle batch is tested by Janoshik Analytical, which we neither own nor control. To request a certificate, email us with the batch number printed on your pack.\u003c\/p\u003e\n\u003cp\u003eA generic PDF with no batch number, no date or no named laboratory is not a batch certificate, and a certificate that reports only one ingredient of a multi-ingredient blend tells you very little.
