## Key points

- An **FDA-approved generic** — the same active ingredient, at the same strengths, as brand-name Viagra.
- One flat monthly price with the clinician review included, rather than a consultation fee stacked on a medication fee.
- Cheaper than the large men's-health platforms for the identical molecule.
- Still dearer than the same tablet bought at a pharmacy with a [free discount card](https://www.edtreatmentguides.com/goodrx-reviews) — the premium buys convenience, not potency.
- Take it 30–60 minutes before sex; a heavy meal delays it noticeably. See the [dosage guide](https://www.edtreatmentguides.com/guides/dosage-guide).

## Scores

| Criterion | Score | Note |
| --- | --- | --- |
| Clinical quality | 4/5 | Asynchronous clinician review with a working pharmacy and reachable pharmacists behind it. |
| Transparency | 4.5/5 | One flat monthly figure with the consultation included, visible before you enter medical history. No introductory rate that later doubles. |
| Value | 4/5 | Among the cheapest subscriptions for this molecule. The same tablet at a pharmacy with a free discount card is still cheaper. |
| Experience | 4.1/5 | Plain, quick and free of upsells. Establish the cancellation route before you start. |
| Privacy | 4/5 | Standard telehealth and pharmacy handling under an established retail parent. |

**Overall: 4.1/5**

## Pros

- FDA-approved generic — the identical molecule to brand-name Viagra
- Flat monthly price with the clinician review included
- No compounded formulation and no proprietary blend on offer
- Pharmacists available to answer questions about the fill
- Meaningfully cheaper than the large men's-health platforms for the same tablet

## Cons

- Still costs more than the same generic at a pharmacy with a free discount card
- Recurring by design — it keeps charging until you stop it
- No video appointment, no blood pressure check, no bloods
- Not available in every state
- Delivery timing means you cannot start today

## Pricing

| Plan | Price | Includes |
| --- | --- | --- |
| Monthly supply | Verify current pricing | Medication, clinician review and shipping in one flat figure |
| Dose change | Verify whether the price moves with strength | Worth confirming, since 25 mg and 100 mg are not always priced alike |

## Verdict

Sildenafil is the cheapest genuinely effective ED drug there is, which makes the price of the wrapper around it the only real variable. This wrapper is a thin one: a flat monthly figure, the consultation folded in, no compounded alternative being steered towards you. Against the well-known platforms that is straightforwardly better value for the same tablet. Against the pharmacy counter it is not, and never will be — what you are buying is the absence of admin. Buy it for that, knowingly, or [take a prescription and fill it yourself](https://www.edtreatmentguides.com/goodrx-reviews) and keep the difference.

## What the money actually buys

Generic sildenafil is a commodity. Multiple manufacturers make it to the same FDA-approved standard, and no service on this site has a better version of it. The price differences between routes are differences in overhead and margin, not in the drug.

- The tablet itself: identical wherever you buy it.
- The clinician review: required by law, and included here rather than billed separately.
- Delivery and reordering: the actual product being sold.
- Brand and marketing: the component that varies most between services, and does nothing for you.

> **Check the 90-day arithmetic**
>
> Per-tablet cost usually falls on longer supplies, at retail and on subscription alike. If you are on a stable dose, ask what a three-month supply costs before defaulting to monthly — and compare that figure with a [discount card price](https://www.edtreatmentguides.com/goodrx-reviews) for the same quantity.

## Getting the dose and the timing right

- [ ] Take it 30–60 minutes before sex, not immediately before.
- [ ] Avoid a large or fatty meal beforehand — it delays absorption substantially.
- [ ] Sexual stimulation is still required; the tablet does not work on its own.
- [ ] Give any dose four to eight proper attempts before calling it a failure.
- [ ] If 50 mg is not enough, that is a conversation about titration, not a reason to give up.
- [ ] Never combine it with any nitrate. Run the [safety check](https://www.edtreatmentguides.com/tools/pde5-safety-check) if you are unsure what counts.

> **A monthly box is not a review**
>
> Refills arriving on schedule is convenient and it is also how three years pass without anyone measuring your blood pressure. ED is an early marker of cardiovascular and metabolic disease — arrange those checks separately, whichever route supplies the tablets.

## Frequently asked questions

### Is this the same as Viagra?

Yes — the same active ingredient, sildenafil citrate, at the same strengths, meeting the same FDA standard for a generic. The difference is the price.

### Is it cheaper than Hims or Ro?

For this molecule it generally undercuts the large men's-health platforms. It does not undercut a retail pharmacy with a free discount card.

### Can I change the strength?

Yes, through the platform's clinician. Confirm whether the price changes with strength before you assume it does not.

### How quickly does it work?

Typically 30–60 minutes, with effect lasting roughly four to six hours. A heavy meal beforehand delays it noticeably.
