Delivered via LG Sciences' liposome tablet technology for improved absorption, it is a cycle-based supplement designed for experienced adult men pursuing serious muscle and strength goals, with mandatory post-cycle therapy following each cycle.\u003c\/p\u003e\n\u003ch2\u003eWhat Is LG Sciences 4-Andro?\u003c\/h2\u003e\n\u003cp\u003eLG Sciences 4-Andro is a non-methylated prohormone supplement containing 75mg of 3β-hydroxy-androst-4-ene-17-one, commonly referred to as 4-Androsterone or 4-DHEA per tablet. It comes in a 60-tablet bottle delivering 60 single-tablet servings, or 30 servings at the two-tablet advanced dose.\u003c\/p\u003e\n\u003cp\u003eA prohormone is a compound that the body converts into a target hormone through enzymatic processes. In the case of 4-Andro, the conversion target is testosterone. It is not testosterone itself, it is a precursor that the body processes into testosterone after ingestion.\u003c\/p\u003e\n\u003cp\u003e4-Andro is a DHEA-derived compound. DHEA (dehydroepiandrosterone) is a steroid hormone naturally produced by the adrenal glands and serves as a precursor to both testosterone and estrogen in the body. The 4-Andro molecule is a structural modification of DHEA specifically oriented toward the testosterone conversion pathway.\u003c\/p\u003e\n\u003cp\u003eThis is a cycle-based supplement. It is not a daily wellness product used indefinitely. Each cycle of 4-8 weeks must be followed by post-cycle therapy. This distinction is critical to using it safely.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThese statements have not been evaluated by the Food and Drug Administration.

The compound does not bypass or override this process it enters the body's existing steroid hormone synthesis pathway and is processed accordingly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis two-step conversion has two practical implications for users:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConversion rate is not 100%. A portion of the 4-Andro dose is metabolised through other pathways or excreted without completing full conversion to testosterone. The actual testosterone yield from a given oral dose depends on individual metabolic factors, which is one reason why the liposome delivery system LG Sciences uses is relevant.\u003c\/p\u003e\n\u003cp\u003eAromatization is possible. Testosterone can convert to estrogen through the aromatase enzyme. 4-Andro has a wet-gains profile meaning estrogen conversion is a real consideration, and users who are estrogen-sensitive may benefit from monitoring this during a cycle.\u003c\/p\u003e\n\u003ch3\u003eLG Sciences' Liposome Delivery Technology\u003c\/h3\u003e\n\u003cp\u003eMost 4-Andro products on the market are basic powder-in-capsule formats.

Understanding the difference is important.\u003c\/p\u003e\n\u003cp\u003eMethylated prohormones contain a methyl group at the 17α position of the steroid molecule. This modification makes the compound resistant to first-pass liver metabolism, improving oral bioavailability but the cost is significant hepatotoxicity. Methylated prohormones place a direct, documented burden on the liver and require liver support supplementation and shorter cycle lengths as a result.\u003c\/p\u003e\n\u003cp\u003e4-Andro is non-methylated. It does not have this structural modification. This means it does not carry the same direct liver toxicity risk profile as methylated prohormones. For users who want the performance support a prohormone offers without the hepatotoxic risk of methylated options, non-methylated compounds like 4-Andro represent a meaningfully different risk profile.\u003c\/p\u003e\n\u003cp\u003eThis is also why LG Sciences' liposome delivery system is particularly relevant for non-methylated compounds as it compensates for the lower natural oral bioavailability that comes with not having the methylation modification, without introducing liver strain.\u003c\/p\u003e\n\u003ch3\u003eWho Is LG Sciences 4-Andro Designed For?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eMinimum age: 21.

The endocrine system continues developing through the early twenties. Introducing exogenous hormone precursors during this period can interfere with the natural hormonal maturation process and cause disruptions that are not easily reversed.

This does not mean it is appropriate for athletes in tested sports see the drug testing section.\u003c\/p\u003e\n\u003ch3\u003e3. Is PCT really mandatory, or just recommended?\u003c\/h3\u003e\n\u003cp\u003ePCT is mandatory. During a prohormone cycle, the body's natural testosterone production is suppressed as it detects the elevated androgen environment. When the cycle ends, production does not automatically recover immediately. Without PCT, users face a period of below-baseline endogenous testosterone associated with muscle loss, fatigue, mood changes, and reduced libido. PCT signals the hypothalamic-pituitary-gonadal axis to resume normal function. Begin PCT the day after your last tablet.\u003c\/p\u003e\n\u003ch3\u003e4. Will 4-Andro cause water retention?\u003c\/h3\u003e\n\u003cp\u003e4-Andro has a wet-gains profile. Because testosterone the conversion product can aromatize to estrogen, water retention is a realistic side effect, particularly at higher doses or in users who are more sensitive to estrogen. Users who want to minimise water retention during a cycle often incorporate an aromatase inhibitor or estrogen management product alongside 4-Andro. This is standard practice for wet-profile prohormone cycles.\u003c\/p\u003e\n\u003ch3\u003e5. Can women use LG Sciences 4-Andro?\u003c\/h3\u003e\n\u003cp\u003eNo. 4-Andro converts to testosterone. In women, elevated testosterone causes virilisation effects including voice deepening, facial hair growth, clitoral enlargement, and disruption of the menstrual cycle. Some of these effects are irreversible. This product is not for women under any circumstances.\u003c\/p\u003e\n\u003ch3\u003e6. Why is the minimum age 21 and not 18?\u003c\/h3\u003e\n\u003cp\u003eThe endocrine system continues developing through the early twenties. The HPG axis the hormonal regulation system governing testosterone, LH, and FSH is not fully mature until approximately 21 years of age. Introducing exogenous hormone precursors before this developmental window closes risks disrupting natural hormonal maturation in ways that may not be easily corrected. Once hormonal maturity is reached post-21, this developmental risk is substantially reduced.\u003c\/p\u003e\n\u003ch3\u003e7. What makes LG Sciences 4-Andro different from generic 4-Andro capsules?\u003c\/h3\u003e\n\u003cp\u003eThe delivery system. LG Sciences uses a liposome tablet format incorporating Phosphatidylcholine 75% and Hydroxypropyl Beta Cyclodextrin (HPBCD) both bioavailability-enhancing technologies that protect the active compound during digestion and improve absorption at the intestinal level. Non-methylated prohormones have naturally limited oral bioavailability due to first-pass metabolism. The liposome system addresses this without introducing the liver toxicity that methylated compounds use the 17α-methyl modification to overcome.\u003c\/p\u003e\n\u003ch3\u003e8. Can 4-Andro be used in tested sports?\u003c\/h3\u003e\n\u003cp\u003eNo. WADA prohibits testosterone and its precursors, including prohormone compounds that convert to testosterone. Any athlete competing under WADA-compliant anti-doping rules including Olympic sports, most professional sports, and a significant number of amateur organisations must not use this product. The US Military also prohibits prohormone use. NCAA and most collegiate sport organisations ban anabolic agents in this category. If you are subject to any drug testing, do not use this product.\u003c\/p\u003e\n\u003ch3\u003e9. How long should the off-cycle period be?\u003c\/h3\u003e\n\u003cp\u003eA minimum of 4-8 weeks off after each cycle, with PCT running throughout the off-period. The off-period serves two purposes: allowing the HPG axis to fully recover natural testosterone production and allowing androgen receptors to restore sensitivity. Shortening the off-period or running back-to-back cycles without adequate recovery increases the risk of prolonged suppression and reduces the effectiveness of subsequent cycles.\u003c\/p\u003e\n\u003ch3\u003e10. Can 4-Andro be stacked with other compounds?\u003c\/h3\u003e\n\u003cp\u003eExperienced users sometimes stack 4-Andro with other prohormones for different synergistic effects for example, combining with 1-Andro for a dry-gains profile that offsets 4-Andro's wet-gains tendency. However, stacking multiple prohormone compounds in the same cycle significantly increases the complexity of the hormonal impact and the importance of proper PCT. Stacking is not appropriate for first-time prohormone users. LG Sciences offers their Bulking Andro Kit, which includes complementary compounds in a pre-designed cycle structure.\u003c\/p\u003e\n\u003ch2\u003eCONCLUSION\u003c\/h2\u003e\n\u003cp\u003eYou now have a complete and honest picture of what LG Sciences 4-Andro is what it does at the molecular level, why the liposome delivery system matters, the full side effect profile, the mandatory PCT requirement, the legal and drug testing context, and who this product is and is not appropriate for. It is a non-methylated prohormone with a well-understood conversion pathway, a superior delivery system within its category, and a usage protocol that demands commitment to the full cycle including post-cycle therapy. If you meet the eligibility criteria adult male, 21+, no relevant health conditions, not subject to drug testing and are prepared to approach it correctly, 4-Andro represents one of the more thoughtfully formulated options in the prohormone space.\u003c\/p\u003e\n\u003ch3\u003eFDA DISCLAIMER\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003e(Place at the bottom of the page, above the reviews section)\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDisclaimer:\u003c\/strong\u003e These statements have not been evaluated by the Food and Drug Administration.
