ATS Labs Anabolic King Review

Anabolic King by ATS Labs is a dietary supplement sold as capsules. According to this page, the product contains twelve active ingredients, and the label presents it for muscle building and anabolic support. The label scan on file is from the NIH Dietary Supplement Label Database (DSLD ID 70566) and is dated February 24, 2017. The page lists a net content of 90 capsules, with a serving size of one capsule and 90 servings per container. The product is marked as on market, as an Other Combinations product type, with a Structure/Function dietary claim and an intended target group of adults aged 18 to 50 years. The active ingredients are grouped into three proprietary blends. Growth Matrix contains 300 mg in total across two ingredients, 5a-Androstan-3Beta-OL-17-One and Androst 3,5-Dien-7,17-Dione. Aromatase Inhibiting Complex contains 265 mg in total across eight ingredients, including Pomegranate extract, White Button Mushroom extract, Chrysin, Luteolin, Kaempferol, Quercetin, Soy Isoflavones and Stinging Nettle. Absorption Amplifier contains 50 mg in total across two ingredients, Black Pepper extract and 6,7-Dihydroxybergmottin. The page states that the label gives no exact amount for any of the twelve active ingredients, which is why its ingredient transparency is rated Low. The other ingredients listed are gelatin, rice, flour and cellulose. The page notes that the ingredient list names soy, and that gelatin is animal-derived. The label carries an FDA disclaimer stating that the statements have not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, treat, cure or prevent any disease. The label also states that the product is proudly made in the USA and is identified as a dietary supplement. On the interaction side, the page reports that 1,292 drugs have a documented interaction with the supplement, and the most serious rating on record is moderate. The interactions come mainly from the Quercetin, Black Pepper, Pomegranate, Chrysin, Stinging Nettle and Arimistane ingredients. The page lists categories such as CYP3A4 substrates, P-glycoprotein substrates, CYP2D6 substrates and antihypertensive drugs. For ingredient research, the page rates Pomegranate as possibly effective for hypertension and Stinging Nettle as possibly effective for diabetes. For pregnancy and breastfeeding, the page rates Stinging Nettle and Black Pepper as likely unsafe in pregnancy, and rates Epiandrosterone as possibly unsafe in pregnancy and breastfeeding. The page advises that people with hormone-sensitive conditions, prostate, liver, kidney or heart problems, and those who are pregnant or breastfeeding should be especially careful, and that users should speak with a doctor or pharmacist before starting. The page does not show a price, a retailer, customer ratings or written customer reviews.

Study, Trial or Testing Result Summary

Members OnlyHuman studies

Anabolic King is sold for muscle building. Its label lists three proprietary blends: a Growth Matrix at 310 milligrams, an Aromatase Inhibiting Complex at 265 milligrams and an Absorption Amplifier at 50 milligrams a day. Because each is a blend, the label does not say how much of any single compound is inside. The store listing says the Growth Matrix holds two hormone-like a med compounds. It says the aromatase complex holds pomegranate, white button mushroom, chrysin, luteolin, kaempferol, quercetin, soy isoflavones and stinging nettle, and the absorption blend holds black pepper extract and a grapefruit compound. We were given no human studies on any of these blends for muscle building, so we cannot say whether the product builds muscle, raises strength or changes hormone levels. With the amounts hidden inside blends, it is also impossible to compare any one ingredient with a dose that has been studied. Only one customer rating was counted. It was positive, but it came from a retailer's own site and reads like marketing, and no independent written reviews could be read. Anyone considering this product should know that the evidence for it is essentially missing, not just weak. Animal and cell studies are never counted.

I could not find a meaningful body of independent customer reviews for Anabolic King. Major retailers such as Amazon and Bodybuilding.com did not return reviews in my search. What exists is thin, so the themes below are tentative. The only on-page customer review I found was a glowing one. It was posted on a wholesale retailer's own site, and it mostly repeats the marketing: explosive strength, lean muscle growth and fat reduction. I treat it as promotional, not independent. The one independent blogger I found tested ATS Labs' sister product, Alpha Mass X, alongside Anabolic King. That blogger had never heard of the company before trying it. He was unimpressed by the Alpha Mass X label, calling several ingredients underwhelming in dose, and he didn't recognise some of the compounds. He said the deer antler velvet in the growth-hormone blend had been hyped but mainly shows promise for recovery. This suggests a wider theme. Buyers and reviewers are skeptical of "proprietary blend" labels that give little transparency on how much of each active is present. Across retailer copy and forum chatter about the category, several themes recur: - **Appeal:** Shoppers like the idea of a "dry," low-bloat product. They also like that it is sold as a stand-alone or as a stack with test boosters or other prohormone-type products. - **Skepticism:** Forum users are generally wary of brands that don't publish third-party testing. There is a perception that the label can't be verified. - **Formula changes:** The ingredient list varies between retailers, from epiandrosterone to HMB plus a flavone plus NMDA. This leaves buyers unsure what they will actually receive. - **Missing data:** I found no verified reports of specific outcomes, such as pounds gained, side effects, or taste or pill-size complaints. Forum posts that surfaced were about other brands, such as King Labs, and are not relevant. In short, there is limited evidence of real-world satisfaction or dissatisfaction. Anyone relying on this should look for current, verified-purchase reviews before drawing conclusions.

RAL Summary

Members OnlyTier 4 for Muscle and Strength

Tier 4 because no human studies were given for any of the three proprietary blends and only one promotional-looking review was counted, so the evidence is too thin to rank higher.

  • Emerging: not enough evidence to rank higher yet.
  • No human studies on this goal for its ingredients.

Body systems: Muscular system, Endocrine system

Combine with: For its actual muscle-building purpose, consider pairing it with creatine monohydrate (3-5 g daily), whey or plant protein to meet daily protein needs, and an EAA or BCAA blend around training. Add vitamin D3 with K2, magnesium, and zinc to support recovery and hormonal health. Because anabolic-type products can stress the liver, lipids, and hormone balance, consider liver support such as milk thistle or NAC, omega-3 fish oil for cardiovascular health, and periodic bloodwork. If the user's real interest is cellular and DNA repair, better-suited supplements include NMN or NR, resveratrol or pterostilbene, CoQ10 or ubiquinol, alpha-lipoic acid, quercetin, and astaxanthin, but these should be discussed with a healthcare provider.

Possible side effects: No major side effects reported.
