What OptiPin's sourced rule file says about Anavar with Winstrol (two 17α-alkylated orals): the combination first, then what each one adds alone, then one bloodwork plan for both. It names markers and red flags, never doses.
This page describes a pair, not you. If you have chest pain, trouble breathing, weakness or numbness on one side, yellowing of your skin or eyes, or shaking, sweating and confusion that could be low blood sugar, get urgent medical care now. Nothing here is a dose, a protocol or a safety verdict.
What the rules say about the combination
2 rules fire only when both compounds are present. Each card is rendered from OptiPin's public, sourced rule file. Its labels show the evidence behind each claim (how we label evidence).
Organ load · each compound affects the same organ or marker; the combination is inferred
More than one 17α-alkylated oral at once Clinical evidence
Flagged by: Anavar, Winstrol
Two or more 17α-alkylated compounds put their liver load on the same organ at the same time. Reviews note that running several compounds together raises the risk of adverse effects.
No study measures this exact combination, so the only read on it is your own liver panel.
Markers to check
ALT, AST, GGT and bilirubin before starting and partway through
How this is usually handled Clinical evidence
Liver injury on these orals usually resolves once the compound is stopped under a clinician's care; for established injury some clinicians add ursodeoxycholic acid (UDCA), though its benefit is unproven. Speak to a clinician.
Get medical care for
Yellow skin or eyes
Dark urine, pale stools or persistent itching
Pain under the right ribs
Evidence
Low for the combination itself (inferred from class effects); moderate for each compound's class.
Several compounds pushing hematocrit at once Clinical evidence
Flagged by: Anavar, Winstrol
More than one compound in this stack is associated with rising red cell mass. For testosterone the effect is dose-dependent, so a second compound plausibly adds to it; that is an inference, not measured.
Nothing has measured these combinations directly, so the CBC is the only read.
Markers to check
CBC (hematocrit and hemoglobin) before starting and partway through
Ferritin and iron studies, if you give blood repeatedly
How this is usually handled Clinical evidence
A high hematocrit needs a clinician, who usually reviews the androgen first. Some doctors recommend therapeutic phlebotomy or blood donation, though evidence that it helps is limited and in one blood-service study repeat donation often did not bring hematocrit down. Repeated draws can also run iron down, so ferritin and iron levels matter.
Get medical care for
Severe headache, vision changes or confusion
Chest pain or sudden shortness of breath (emergency services)
A painful swollen leg
Evidence
Low for the combination (inferred from dose-response data); strong for testosterone alone.
The modification that lets these compounds survive being swallowed also slows their clearance through the liver. Liver injury, cholestasis and lipid changes are documented with this class.
Injury with this class is often cholestatic, which is why bilirubin and GGT sit on the panel alongside ALT and AST.
Markers to check
ALT, AST, GGT and bilirubin before starting and partway through
Heavy weightlifting alone can raise ALT and AST for at least a week; bilirubin and GGT were not raised in the same study
How this is usually handled Clinical evidence
Liver injury on an oral usually resolves once the compound is stopped under a clinician's care; for established injury some clinicians add ursodeoxycholic acid (UDCA), though its benefit is unproven. Speak to a clinician.
Get medical care for
Yellow skin or eyes
Dark urine, pale stools or persistent itching
Pain under the right ribs
Evidence
Moderate: consistent case series and reviews for the class.
In a small crossover study, oral stanozolol cut HDL cholesterol far more than injected testosterone did and raised LDL. Oral 17α-alkylated compounds as a class are known for this.
A lipid shift like this adds to cardiovascular risk while it lasts.
Markers to check
Lipid panel (HDL, LDL, triglycerides; ApoB if available) before starting and partway through
Get medical care for
Chest pain or pressure (emergency services)
Evidence
Moderate: small crossover study (11 male weightlifters, 6 weeks) plus consistent class data.
This stack suppresses your own testosterone production while it runs. Recovery after stopping usually takes 6–18 months; in one study some former long-term users still had low testosterone up to two years later.
In one study of former users, 29% had a major depressive episode during withdrawal.
Markers to check
LH, FSH and total testosterone before starting and again after stopping
How this is usually handled Clinical evidence
Low testosterone after stopping is usually managed under a clinician with a SERM such as clomiphene, hCG or testosterone therapy depending on the case; speak to a clinician.
Get medical care for
Low mood, low libido or erectile problems that persist months after stopping (see a doctor)
Every marker the rules above name, listed once. Take it to your clinician or lab.
ALT, AST, GGT and bilirubin before starting and partway through (17α-alkylated compound: liver load; More than one 17α-alkylated oral at once)
Heavy weightlifting alone can raise ALT and AST for at least a week; bilirubin and GGT were not raised in the same study (17α-alkylated compound: liver load)
Lipid panel (HDL, LDL, triglycerides; ApoB if available) before starting and partway through (Oral compound: HDL drops sharply)
CBC (hematocrit and hemoglobin) before starting and partway through (Several compounds pushing hematocrit at once)
Ferritin and iron studies, if you give blood repeatedly (Several compounds pushing hematocrit at once)
Estradiol (sensitive assay) partway through (Nothing here converts to estradiol)
LH, FSH and total testosterone before starting and again after stopping (Own production shut down)

What each compound is
Anavar (oxandrolone). An oral anabolic steroid that is 17α-alkylated. That modification lets a steroid be taken by mouth. Its slower clearance through the liver also makes it more toxic to the liver. More on Anavar.
Winstrol (stanozolol). An anabolic steroid taken orally or as an injectable suspension. Both forms are 17α-alkylated. More on Winstrol.
Log a cycle in OptiPin and it shows whether the stack converts to estradiol, which compounds are 19-nors or 17α-alkylated, when red cell count tends to climb and when your own production is shut down, each with the marker that reads it. All on-device.
