SkinnyRx vs MyFastRx
Two GLP-1 programs on the bench, scored on the same six factors. Here's how their real cost of ownership compares — and which one we'd start with.
SkinnyRx
Shoppers who have already decided on a long commitment and want the term priced openly rather than hidden behind an intake — not price-first shoppers comparing on the advertised figure.
Visit SkinnyRxMyFastRx
Cost-first shoppers who want cash-pay shoppers comfortable prepaying several months upfront to reach the lowest per-month compounded-GLP-1 rate on the market.
Visit MyFastRxThe verdict
MyFastRx takes it, leading the Cost-Efficiency Index 73 to 71. MyFastRx is a cash-pay compounded-GLP-1 platform with a full published price ladder: a $139/mo semaglutide and $199/mo tirzepatide standing month-to-month rate, a discounted first month with a promo code. SkinnyRx still earns a C — Shoppers who have already decided on a long commitment and want the term priced openly rather than hidden behind an intake — not price-first shoppers comparing on the advertised figure.

SkinnyRx
71/100Where the value is
- A complete four-term ladder for both molecules is published rather than gated, so the cost of not committing is knowable before signup
- Both compounded molecules are offered, with the same term structure on each
- The twelve-month rate is genuinely low for the category if a year is a commitment you were going to make anyway
The tradeoffs
- The '$199/month' it advertises everywhere is the TWELVE-MONTH rung. The rate you can stop after a month is $349 — 75% higher — and the figure appears without that term attached
- An FDA warning letter is on public record against Lean Rx, Inc. dba SkinnyRx, issued 20 February 2026. We disclose it and we do not treat it as disqualifying
Regulatory note: the FDA issued a warning letter to Lean Rx, Inc. dba SkinnyRx in February 2026. We still list and link to SkinnyRx; you should know the letter is on the public record before you decide.
MyFastRx
73/100Where the value is
- Publishes a full, specific price ladder (1/3/6/12-month) rather than a single vague 'starting at' figure
- LegitScript certified
- Flat pricing across all doses — no dosage upcharges as you titrate
The tradeoffs
- The true no-commitment monthly rate ($139 sema / $199 tirz) is meaningfully higher than the deep prepay-bundle rates the marketing emphasizes ($79-99 / $124-166) — those low numbers require paying for 3, 6, or 12 months upfront
- The lowest first-month price ($69 / $129) requires entering a promo code and applies to one month only
