Start with the trade-off: what pays you, and when
Most programs in this group pay you on completed sales, so the first comparison is what counts as a sale and what that sale pays. TestRX pays a share of every sale, VigRX Plus adds a per-sale amount on top of its share, ProSolution Plus works on a revshare, and Dr.Cash pays a fixed amount per nutra offer.
CashKaro sits apart from the rest of the group. It runs a referral scheme rather than a health offer, pays 10% of friend's cashback, and also carries a recurring commission, so the reward repeats for as long as the referral keeps earning.
Commission terms and what a sale is worth
TestRX pays 50% per sale and reaches publishers through SellHealth, so one network relationship covers the whole offer list.
VigRX Plus runs on cps and revshare models at 50% commission, with a per-sale amount of $245. A fixed amount alongside the share gives you two ways to read the same sale.
ProSolution Plus pays 40% revshare per sale and lists $172 per sale, a structure that rewards a publisher already selling that specific product.
Dr.Cash uses a cpa model and pays CPA per nutra offer, which suits publishers who would rather track a single amount per conversion than a percentage.
Check the cookie window before anything else
Across the offers tracked in this group, cookie windows run 30 to 45. The window sets how long a click stays credited to you, so compare it against how long your audience takes to decide rather than against commission size alone.
A shorter window suits traffic that converts on the first visit. A longer one gives a hesitant reader time to come back, which is why the same rate can be worth more or less depending on the traffic you already have.
Payout rules and how fast money moves
Dr.Cash pays twice daily and lists a minimum payout of $10 against a threshold of $50, so balances can be withdrawn often once the floor is passed.
VigRX Plus pays Bi-weekly, which means a smaller balance waits longer between withdrawals and needs to be planned for.
CashKaro sets its threshold at INR 250 and pays out by bank transfer and gift card, so the choice of payout route matters as much as the amount.
Where each program operates
CashKaro is the most local of the group. Founded in 2013, it covers retail, travel and health, lists its region as single country and keeps its headquarters in IN.
Dr.Cash is the broadest. Operating since 2016, it lists global as its region, keeps its headquarters in IE and sits behind the legal entity MARKETING IT WAY LIMITED. VigRX Plus also lists global as its region, so it travels further than a single-market program.
Support is worth weighing alongside reach. CashKaro offers help centre, while Dr.Cash offers email and chat and describes its offer style as direct.
How offers are accessed, and who else uses them
TestRX and VigRX Plus both sit on SellHealth, so a single network approval can open both. Dr.Cash instead runs on own in house platform and reports 173,455 publishers, which tells you how many others are bidding on the same offers.
Vertical fit narrows things further. CashKaro covers retail, travel and health, while health, health and health describe the focus of the health offers. A single-sector focus is a narrower proposition, and it is an easier one to write about accurately.
A workable way to decide
Start from your market and your payout rhythm. If your readers sit in the country CashKaro serves and you prefer a referral earn, its threshold of INR 250 tells you what balance you need before withdrawing.
If you sell health products directly, TestRX and VigRX Plus pay a share of the sale through the same network, VigRX Plus adds $245 per sale on a Bi-weekly schedule, and ProSolution Plus lists from 40% with $172 per sale.
If payout frequency matters most, Dr.Cash pays twice daily and runs on its own platform. The health and wellness programs ranking sets these options against each other, and the SellHealth review covers the network two of them sit on.
