Lower numbers = closer to natural. Higher numbers = more enhanced.
Why this rating?
Telmisartan is an FDA-approved angiotensin-receptor blocker (ARB) for hypertension. It is not a performance enhancer. It controls blood pressure and improves insulin sensitivity/lipids. In the PED world it is a support medication run alongside a cycle to manage the blood-pressure rise that androgens (especially trenbolone and high-dose testosterone) cause. Not WADA prohibited. Rated 1 (basically natty): it manages blood pressure and metabolic markers but does not build muscle, burn fat, or raise anabolic hormones, so it does not move the physique/performance ceiling at all.
Overview
A long-acting angiotensin II receptor blocker (ARB) used to lower blood pressure. Among ARBs it is uniquely also a partial agonist of PPAR-gamma, the target of the 'glitazone' insulin-sensitising drugs. That dual action: blood-pressure control plus favourable effects on insulin sensitivity and lipids, is exactly why it became the community-favourite blood-pressure drug for people on cycle, where androgens routinely drive blood pressure up.
Important Warnings
- •ARBs are teratogenic, contraindicated in pregnancy (fetal toxicity); women who could become pregnant must use reliable contraception.
- •Do not stack multiple blood-pressure drugs without monitoring. Combined hypotension can be dangerous.
- •Can raise potassium. Avoid potassium supplements/salt substitutes and potassium-sparing diuretics without labs.
- •Caution with NSAIDs and dehydration (contest prep), additive kidney strain.
- •Telmisartan controls blood pressure but not hematocrit; high red-cell count still needs to be managed (e.g. blood donation).
- •It is not an AI or hormonal drug. It does nothing for estrogen; treat estrogen and blood pressure as separate problems.
Purpose & Use Cases
On-Cycle Blood Pressure Control
The reason it is the community pick. Aromatizing and androgenic compounds raise blood pressure via water retention, altered vascular tone, and rising hematocrit; telmisartan brings it back down with once-daily dosing.
Insulin Sensitivity
Its partial PPAR-gamma agonism improves insulin sensitivity and raises adiponectin, a genuine advantage over other ARBs, and useful during high-calorie bulks or growth-hormone/insulin protocols.
Lipid / Metabolic Support
PPAR-gamma activity favourably influences triglycerides and metabolic markers, helpful given that many oral steroids and AIs worsen the lipid profile.
Cardiovascular / Renal Protection
As with other ARBs, blood-pressure reduction confers cardiovascular and kidney protection, relevant to anyone applying chronic cardiovascular stress with androgens.
Benefits
- Effective once-daily blood-pressure control (longest-acting ARB)
- Improves insulin sensitivity via partial PPAR-gamma agonism
- Favourable effect on triglycerides/lipids vs other ARBs
- No ACE-inhibitor dry cough
- Raises adiponectin; metabolically 'friendly' for lifters
- Well-studied, inexpensive, non-hormonal
Good to Know
The go-to on-cycle blood pressure tool
Telmisartan is an ARB (blocks angiotensin II) that lowers the blood pressure anabolics reliably raise. It is favored over other BP meds because it is also a partial PPAR-gamma agonist, so it can improve insulin sensitivity and lipids, useful on cycle.
Why it beats older ARBs here
Its long half-life gives smooth 24-hour coverage, and the PPAR-gamma activity is a metabolic bonus most other ARBs lack. Dose it to your actual blood-pressure readings, not by default.
Not a doping agent
ARBs are not diuretics and are not on the WADA list, so telmisartan is a legitimate health-support tool rather than a prohibited substance.
Dosage Guidelines
| Experience Level | Dosage Range |
|---|---|
| Beginner | 20 – 40 mg/day |
| Intermediate | 40 – 40 mg/day |
| Advanced | 40 – 80 mg/day |
Usual starting dose is 40mg once daily; the effective range is 20-80mg. Doses above 80mg give little extra blood-pressure reduction. Most of the effect appears within 2 weeks and is maximal by ~4 weeks, so titrate against actual cuff readings rather than chasing it day to day. Blood pressure is the number that matters, buy a home monitor and dose to keep it in range, not by feel.
Terminal half-life ~24 hours: the longest-acting ARB, giving true once-daily, full 24-hour coverage.
Side Effects
Dizziness / Hypotension
commonLightheadedness, especially on standing, if blood pressure drops too far or when combined with other antihypertensives.
Start at 20-40mg; stand up slowly; do not stack multiple BP drugs without monitoring.
Hyperkalemia
uncommonARBs can raise potassium, particularly with potassium supplements, potassium-sparing diuretics, or kidney impairment.
Avoid potassium supplements/salt substitutes without monitoring; check labs if using long-term or with renal issues.
Reduced Kidney Function (contextual)
uncommonBy altering intrarenal pressures, ARBs can raise creatinine, especially with dehydration or NSAID use, a real consideration for lifters who run dehydrated (contest prep) or use a lot of NSAIDs.
Stay hydrated; be cautious combining with NSAIDs; monitor renal function on longer runs.
Angioedema
rareRare swelling of face/lips/throat; a medical emergency if it affects the airway.
Stop immediately and seek care if swelling occurs.
General Mitigation Strategies
The main risk is over-shooting blood pressure downward, so titrate from a low dose against home cuff readings. Watch potassium (avoid potassium supplements/salt substitutes) and stay hydrated, especially if also running diuretics or an aggressive cut. Telmisartan lowers blood pressure but does NOT lower hematocrit, if a high red-cell count is driving your pressure, that is addressed by donating blood, not by the ARB.
Post Cycle Therapy (PCT)
Not hormonal. No PCT required. May be continued indefinitely for blood-pressure management.
How It Works
As an ARB, telmisartan selectively blocks the angiotensin II type-1 (AT1) receptor, preventing angiotensin II-driven vasoconstriction and aldosterone release. Arteries relax and blood pressure falls, without the dry cough seen with ACE inhibitors. Separately, and unusually for its class, telmisartan is a selective partial PPAR-gamma agonist (activating the receptor to roughly 25-30% of a full agonist). Through PPAR-gamma it improves insulin sensitivity, raises adiponectin, and favourably shifts triglycerides/lipids, metabolic effects most other ARBs largely lack. It is highly lipophilic with a ~24-hour half-life, so one daily dose covers the full day.

Legal Status
FDA-approved prescription medication for hypertension and cardiovascular risk reduction.
Legal status varies by country and changes over time. This is a general summary, not legal advice.
WADA Status
Telmisartan is an angiotensin-receptor blocker (antihypertensive). ARBs are not on the WADA Prohibited List and are permitted in and out of competition.
