Thanks for reaching out and looking into purchasing the Red Growth & PCT Bundle. No you do not need to buy a 2nd bottle of Red-PCT.
If you take 1 capsule of Red-PCT everyday with your Red Growth then that will equal 30 capsules. There are 90 capsules in each bottle of Red-PCT.
When you begin your PCT cycle after Red Growth, you will be able to take 3 capsules of Red-PCT a day for 20 days–finishing off the remaining 60 capsules.
That's just about 3 weeks of PCT, which combined with the 4 weeks of pre-PCT that you took while you were on Red Growth should be totally sufficient to help you maintain your gains and keep your hormones balanced.
