Andarine 10mg/tab 60 Tabletten by Elbrus Pharmaceuticals

4.5 (2 reviews)

Andarine (S-4) is a non-steroidal SARM developed to selectively activate androgen receptors in skeletal muscle and bone, making it a primary choice for athletes seeking simultaneous fat loss, muscle hardness, and enhanced vascularity during a caloric deficit. Each 10 mg tablet provides exact, repeatable dosing — removing the measurement variability common with liquid S-4 formats and enabling clean titration across a split-dose schedule. Potency and purity are confirmed at the finished-tablet level: every production batch passes HPLC concentration analysis and LAL endotoxin testing, with both outcomes recorded against a lot number before distribution begins.

  • Promotes skeletal muscle hardness by upregulating AR-dependent protein synthesis pathways — no aromatisation, no oestrogen-related water retention
  • Enhances vascular visibility on a cut by preserving lean mass while subcutaneous fat decreases
  • Delivers precise 10 mg increments per tablet, enabling clean dose titration across a split-dose schedule
  • Does not convert to DHT, eliminating a key driver of scalp and prostate-related androgenic side effects
  • Maintains bone mineral density signalling via selective AR activation — relevant for athletes in prolonged caloric deficit
  • Each production batch carries a lot-referenced HPLC potency report and LAL endotoxin certificate before release
  • Blister strip packaging protects individual tablets from moisture and light degradation throughout the 60-tablet supply period

Key takeaways

  • Choose Andarine S-4 for a harder, drier aesthetic without water retention.
  • Split your daily dose to reduce peak plasma levels and limit vision side effects.
  • Expect visible vascularity improvements as subcutaneous fat decreases on a cut.
  • Verify each batch: Elbrus documents HPLC potency and LAL endotoxin results per lot.
  • Discontinue or reduce dose promptly if yellow-tint vision becomes disruptive.

What Andarine (S-4) Actually Does — Hardness, Vascularity, and the Mechanism Behind Both

Andarine (S-4) is a non-steroidal selective androgen receptor modulator that preferentially activates AR-dependent transcription in skeletal muscle and cortical bone tissue, producing a dense, "dried-out" aesthetic that users describe as muscle hardness without the water retention associated with anabolic steroids. Unlike broad-acting androgens, S-4 does not aromatise to oestrogen and does not convert to DHT, two processes responsible for subcutaneous water retention and the soft look many cutting athletes try to avoid. The hardness effect is not cosmetic illusion — Andarine promotes myofibrillar density by upregulating protein synthesis genes downstream of AR activation, a mechanism confirmed in preclinical models using validated AR-reporter assays.

Vascularity improves alongside hardness for a related reason: as subcutaneous and intramuscular fat decreases and muscle fibre volume stays stable or increases, blood vessels lying close to the skin surface become more visible. S-4 accelerates this process compared to diet alone because it maintains lean mass during a hypocaloric phase — a significant advantage, because muscle loss on a cut typically reduces the very fullness that makes veins prominent. Elbrus Pharmaceuticals' 10 mg tablet format allows users to manage total daily exposure with precision, which matters for a compound where dose-dependent response is well documented.

The Vision Side Effect of S-4 — Explained Clearly

Andarine produces a distinctive, dose-dependent side effect: a yellow-green tint to vision and reduced adaptation to low-light environments. This occurs because S-4 and its metabolite (specifically metabolite M1) bind to the androgen receptor in the ocular retina, particularly in rod photoreceptors responsible for scotopic (low-light) vision. The effect is reversible — visual disturbance resolves when the dose is reduced or the compound is discontinued, typically within days to weeks. Most users report the tint is most noticeable when transitioning from bright outdoor light to indoor or dim settings. Managing this side effect is straightforward: splitting the daily dose into two administrations (morning and early afternoon) lowers peak plasma concentration and reduces retinal AR occupancy at any single point in the day.

Dosing Strategy and Lab-Verified Quality

The clinical and community evidence base points to 25–50 mg/day as the functional range for aesthetic outcomes, with vision sensitivity increasing meaningfully above 50 mg/day. Elbrus Pharmaceuticals manufactures the S-4 10 mg tablet under GMP-aligned conditions; every production batch undergoes HPLC-based potency analysis and LAL endotoxin testing before release — not as a marketing claim, but as a documented, lot-number-referenced gate. This batch-level traceability means the 10 mg declared on the label corresponds to a verified analytical result, not an assumed equivalence to a raw material certificate.

Usage

  1. Establish your baseline before starting: note any pre-existing visual sensitivities or low-light adaptation issues, as S-4 will temporarily affect rod photoreceptor function and you need a clear reference point.
  2. Start with one 10 mg tablet in the morning on Day 1 and assess your response for the first 48 hours before increasing — even if your target dose is higher.
  3. Once your introductory phase is complete, divide your total daily dose into a morning tablet and an early-afternoon tablet; avoid late-evening dosing as this is when low-light vision impairment is most noticeable and most disruptive.
  4. Take each tablet with a small meal or snack — S-4 is lipophilic and absorption consistency improves when administered with dietary fat.
  5. Monitor vision quality actively throughout your cycle: a mild yellow-green tint or slower dark-adaptation is expected at therapeutic doses; if the tint is severe or vision is compromised in normal lighting, reduce dose by 10 mg immediately.
  6. Plan your cycle length to a maximum of 8 weeks followed by a minimum 4-week off period and appropriate PCT; S-4 suppresses endogenous testosterone production and post-cycle hormonal recovery must be supported pharmacologically.

Warnings

Contraindications: Andarine S-4 is not suitable for individuals under 18 years of age, women who are pregnant or breastfeeding, or anyone with a history of retinal disease, photosensitivity disorders, or colour vision deficiency. Individuals with pre-existing hepatic impairment should not use S-4, as androgen receptor modulators require functional hepatic clearance.

Side Effects: The most characteristic side effect is reversible retinal binding causing yellow-tinted or greenish-tinted vision and impaired scotopic (low-light) adaptation — this is dose-dependent and resolves on dose reduction or cessation. Testosterone suppression occurs at therapeutic doses and is significant enough to warrant post-cycle therapy. Mild transaminase elevation has been observed in some users; liver enzyme monitoring is advised for cycles exceeding four weeks.

Monitoring: Monitor serum testosterone, LH, FSH, and ALT/AST at baseline and at cycle end. Track vision quality subjectively throughout the cycle — keep a simple daily note of whether the yellow tint is worsening, stable, or improving. Blood pressure should be checked periodically if cardiovascular risk factors are present.

PCT: Post-cycle therapy with a SERM (tamoxifen or clomiphene citrate) is recommended following any S-4 cycle of four weeks or longer. Begin PCT within 3–5 days of the final dose. Standard SERM protocols of 4 weeks are generally sufficient given S-4's short half-life and the relatively faster hormonal recovery compared to longer-acting compounds.

Frequently asked questions

What is Andarine (S-4) most commonly used for during a cutting phase?
Andarine is primarily used during a cut to preserve lean muscle mass while body fat decreases, producing a harder, more vascular appearance. Its partial agonist activity at androgen receptors in skeletal muscle prevents the catabolism that typically accompanies a caloric deficit, allowing users to maintain — and in some cases improve — muscle fullness and visible vascularity without retaining subcutaneous water.
Why does Andarine S-4 cause yellow or tinted vision, and is it permanent?
The visual side effect occurs because S-4's metabolite M1 binds androgen receptors in the retinal rod photoreceptors, impairing low-light and colour adaptation. This is a dose-dependent and fully reversible effect — the yellow-green tint and difficulty adjusting to dim conditions resolve within days to a few weeks after dose reduction or cessation. It is not a sign of permanent retinal damage.
How do you minimise the vision side effects of Andarine while still getting results?
Splitting the total daily dose into two smaller administrations — typically morning and early afternoon — lowers peak plasma concentration and reduces maximum retinal AR occupancy at any single time point. Most users who stay within 25–50 mg/day and divide doses this way report manageable or negligible visual disturbance. Doses above 50 mg/day significantly increase the likelihood and severity of visual symptoms.
How do the 10 mg tablets from Elbrus Pharmaceuticals make dosing Andarine more practical?
A 10 mg tablet format allows users to dial in their exact daily intake with one-tablet precision — 25 mg, 37.5 mg, or 50 mg per day can be approximated cleanly across split doses. This level of control is harder to achieve with liquid S-4 preparations, where volumetric measurement error is common. Each tablet's declared potency is backed by batch-level HPLC verification, so the dose on the label is the dose in the tablet.
Are Elbrus Pharmaceuticals Andarine tablets supplied in blister packs, and does that affect shelf stability?
Yes, the 60-tablet supply is presented in blister strip packaging, which provides individual compartment isolation from moisture and light — two primary factors that degrade SARM potency over time. Blister packs also make it straightforward to track daily consumption and maintain a consistent dosing schedule, which is particularly important for a compound like S-4 where consistent dosing intervals help manage peak plasma levels and minimise vision-related side effects.

Manufacturer

The quality commitment behind Elbrus Pharmaceuticals' S-4 tablet line is best understood not as a set of procedures, but as a response to a specific failure mode the brand's founders observed in the research-compound market: the systematic disconnection between raw-material certificates and finished-tablet reality. A supplier's certificate of analysis confirms what was in a drum of API — it says nothing about what survived granulation, compression, and blending to reach the individual tablet a user swallows. Elbrus treats this gap as the central quality problem to solve, not an administrative formality to paper over. For the Andarine 10mg tablet specifically, the solution is a two-checkpoint release architecture: incoming API is assessed for identity and purity before it enters the manufacturing process, and the finished compressed tablet — the actual product, not the bulk powder — is re-analysed by HPLC for confirmed potency and by LAL assay for endotoxin content before a lot number is assigned for distribution. Both results are retained as lot-referenced records. This structure means that when a user reads "10 mg Andarine S-4" on the label, the number corresponds to a documented analytical finding from the finished tablet matrix — not an extrapolation from upstream paperwork.

    Hardest I've looked on a cut

    8 week recomp at 25mg ed (split 10mg/10mg/5mg across the day). Came in at 88kg from 93kg and look considerably drier and more vascular. Heard about the yellow tint vision thing, got very mild at week 5 at sunset but went away quickly and wasn't an issue during training. Bloodwork showed test sat fine. Elbrus tabs are consistent, delivery was discreet and fast

    Solid but tabs hard to split evenly

    Running 25mg ed which means splitting tabs and these ones crumble a bit when you try to cut them. Results are decent though, noticeable hardness and vascularity from week 3 on a 500 cal deficit. Down 4kg over 10 weeks, kept all lifts. Would prefer scored tabs for accurate dosing at lower amotnts, hence the 4 stars, but the compound itself works 👍
