So ? is On S4 50mg to 75mg ED for 4to6 weeks is an OTC PCT proper? Ive read some logs saying No need for a SERM Just a Natty Test Booster after and on cycle support and your good to go. While others say you need a SERM. If you do need a SERM Im assuming Clomid/Novla but havnt seen a single log showing what the dosage would look like. Any Feedback?
