Hey!
Don't worry, Lymecycline (Tetralysal) won't 'kill' your gains.
It works by inhibiting protein synthesis in bacteria, but it doesn't affect human muscle protein synthesis.
Studies on healthy individuals show that tetracycline-class antibiotics have no negative impact on muscle strength, enzyme activity, or 𝑉𝑂2 max.
A few things to keep in mind:
Gut Health: The only way it might indirectly affect your progress is through your gut microbiome. If your digestion gets hit, it might slightly affect nutrient absorption or your energy levels. Adding a probiotic to your routine can help mitigate this.
Supplements: If you're taking Zinc, Magnesium, Iron, or calcium supplements, make sure to space them out. Take them at least 2–3 hours apart from the Lymecycline, as they can significantly decrease the antibiotic's absorption.
Transitioning to Accutane: This is the part where you need to be more careful. Isotretinoin is known to cause joint and muscle pain in some lifters. It also puts stress on the liver, which is a major factor if your 'cycle' includes any orals.
CRITICAL SAFETY: Do NOT overlap Lymecycline and Accutane.
Combining them can cause a dangerous spike in intracranial pressure (pseudotumor cerebri). Make sure there is a clear gap between finishing the antibiotic and starting the isotretinoin.
Bottom line: You’re good to keep training hard.
Lymecycline won't mess with your hypertrophy.
Good luck with the skin!
